Bone Metabolism Defects Common in Untreated Children With Celiac Disease
They compared serum levels of calcium, magnesium, 25(OH) vitamin D3, alkaline phosphatase and parathyroid hormone of CD patients. Compared with the controls, children with celiac disease had significantly lower concentrations of calcium and 25(OH) vitamin D3 and significantly higher concentrations of parathyroid hormone (p < 0.001). Twenty-nine subjects (53.7%) with celiac disease had hyperparathyroidism.
Of the 20 children with celiac disease who tested positive for two alterations on laboratory measurement and underwent dual energy X-ray absorptiometry (DEXA), 10 were osteopenic (z-score between –1 and –2.5).
"In line with other studies involving children diagnosed with celiac disease before 9 years of age," the authors note, all the laboratory findings returned to normal after 6 months of a gluten-free diet, with improvement in bone mineral density and resolution of osteopenia.
These observations, they say, confirm that in this population at least, "bone metabolism abnormalities are part of the gluten-dependent clinical picture of celiac disease."
Bonnie - what a well conceived and important study for the medical community to take note of. Of course bone metabolism will be an issue for those with celiac disease who are still eating gluten. Simply, the malabsorption issues one has with celiac or gluten intolerance will not allow minerals such as calcium to be adequately utilized. Hence, when gluten is removed, absorption becomes normal again.

What are Nutritional Concepts Action Plans?
Lack of B12 Linked to Brain Shrinkage
Failure to properly absorb vitamin B12, found in meat, milk and eggs, has been implicated in various neurological disorders. Now a British study suggests that low levels of the vitamin in older people may cause the brain to shrink.
The study, published Tuesday in Neurology, included 107 men and women, average age 73, who had no mental impairments. Researchers used M.R.I. scans to measure brain volume and blood tests to record vitamin B12 levels. They divided the subjects into three groups, based on their level of the vitamin, and followed them for five years with annual scans and physical and mental examinations.
The group with the lowest levels of vitamin B12 lost twice as much brain volume as those with the highest levels. The difference was significant even after controlling for initial brain size, age, sex, education, cognitive test scores and various measures of blood chemistry.
David Smith, an emeritus professor of pharmacology at Oxford and the lead author of the study, said the work established an association, but not a causal connection.

Bonnie - while this may be a surprise to the medical community, it is not to nutritionists who have been prescribing vitamin B-12 to the elderly for decades.

Tips on Switching to a Positive Outlook:
While working with unhappy clients, psychologist and author Dan Baker draws on the science that shows that half of our happiness is genetic, but as much as 40% is up to us. "That 40% is huge," says Baker, who is the founding director of the life enhancement program at Canyon Ranch, an upscale spa and resort in Tuscon and the author of "What Happy Women Know" (Rodale, 2008), a sequel to his bestselling "What Happy People Know" (St. Martin's, 2004).To help clients rewire their unhappy outlook, he offers this three-part prescription. For the next week, do these things daily:
1. Every morning when you wake up, think of someone or something that you have a deep and abiding appreciation for: a former teacher or coach, a neighbor, a parent or friend. Do the same just before lunch. At night, when you get in bed, think of something that occurred that day that you appreciate.
2. Do something for someone else. Call a friend or send her an e-mail. Give a toy to charity.
3. Curb your negative self-talk. When thinking of a forthcoming event, such as the birth of a baby or having the family over for Thanksgiving, don't focus on the pain or hassles. Focus on the possibilities -- and on what's good and special about the event.
"It only takes a couple minutes each day to eventually build up a new neural network," Baker says.
Keep up these new behaviors until they turn into habits.

FDA posts list of potential problem drugs
The government on Friday began posting a list of prescription drugs under investigation for potential safety problems in an effort to better inform doctors and patients.
The first list is a bare-bones compilation naming 20 medications and the potential issue for each. It provides no indication of how widespread or serious the problems might be, leading some consumer advocates to question its usefulness, and prompting industry worries that skittish patients might stop taking a useful medication if they see it listed.
Food and Drug Administration officials said they are trying to walk a fine line in being more open to the public while avoiding needless scares. Congress, in a drug safety bill passed last year, ordered the agency to post quarterly listings of medications under investigation.

Organic food to be cheaper than other produce
It is currently regarded as a luxury purchase by shoppers, who have been forced to turn to lower cost, intensively-farmed produce by the economic downturn.
But a study suggests that the price of oil could soon make cereal crops grown with fertiliers more expensive than those produced more naturally.
Industrial farming relies on fossil fuels to mine, manufacture and transport fertilizers which replace nutrients in the soil.
Organic farming, however, improves soil fertility through crop rotations and is less affected by oil prices.
Peter Melchett, policy director of the Soil Association which promotes organic farming, said: "This study suggests that as oil inevitably becomes scarcer and costs more, economic forces will increasingly favor organic farming.
August Research Highlghts
AJCN -
- Nutrition experts are now calling for B-12 fortification in addition to the already existing folate fortification in food. This will assure that B-12 deficiencies will not be created by excess folate.
- Regular consumption of soy protein foods had no significant effect on lowering plasma LDL cholesterol in mildly hypercholesterolemic subjects.
- Exclusive breastfeeding may be associated with lower blood cholesterol concentrations in later life.
- Previous associations between carotenoids (beta carotene) and increased risk of lung cancer are misguided and not seen as a causal risk factor.
- Diet and exercise under supervision of a health professional results in a significant decrease in body weight in women and men. However, this decrease was not maintained at one year follow-up. This supports the idea that periodic or sometimes intensive supervision is necessary for maintaining the positive results of a weight-loss program.
- Ingestion of ground flaxseed, flaxseed oil, or flaxseed powder, while know for its omega-3 content, did not increase EPA/DHA levels in this study's subjects. This echoes the fact that plant sources of omega-3 (flax, chia, hemp, etc.) are poor converters to EPA/DHA.
- Lower folate status in African-American women may also be associated with lower choline status.
- Body size should be taken into account when estimating the amount of vitamin D intake needed to raise 25(OH)D to the desired level.
- Internal medicine interns' perceive nutrition counseling as a priority, but lack the confidence and knowledge to effectively provide adequate nutrition education.
- Young children should receive at least 70-100 mg. of supplemental magnesium daily

High protein breakfast could aid weight loss
Eating more protein in the morning helps create the feeling of being full throughout the day and could help dieters lose weight. The timing of a meal is a key factor as a greater sense of fullness is experienced after a high protein breakfast compared to when more protein is eaten at lunch or dinner, the report published in the British Journal of Nutrition said.
The Purdue University study looked at overweight or obese men who ate a reduced calorie diet. The diet consisted of two variations of protein intakes, both which were within federal nutrition recommendations. The first was a normal protein intake (or 11-14 percent of calories) and the second was increased protein (or 18-25 percent of calories).
The researchers tested the effect of consuming the additional protein at specific meals, breakfast, lunch or dinner, or spaced evenly throughout the day.
They found that the feeling of fullness was greatest and most sustained throughout the day when the additional protein, from high-quality protein foods was eaten at breakfast.
The authors said that most Americans typically consume a relatively small amount of protein at breakfast, which is only about 15 percent of their total daily protein intake.
Bonnie - they're finally starting to catch on!!
Folate may protect colon from DNA damage
Low levels of dietary folate may increase the risk of DNA damage in colon cells, and ultimately the risk of cancer, suggests researchers in the United Kingdom and Texas who combined proteomic and biochemical approaches to show that proteins known to play a part in formation of cancer are affected by low folate levels. Such a relationship was “hitherto unrecognized”, wrote the researchers in the Journal of Proteome Research.
Previous studies have already suggested that folate deficiency may promote the risk of colorectal cancer. The subject of folate and colorectal cancer is controversial, however, with some studies reporting that the B-vitamin may in fact increase the risk of the disease. On the other hand, other studies have reported protective benefits from folate for colorectal cancer.
The Aberdeen-based researchers, in collaboration with scientists from the Incell Corporation in San Antonio, Texas, used functional biomarkers combined with proteomics to elucidate the mechanisms behind changes to DNA caused by folate deficiency in a human colon cells.
Proteomics is the study of proteins that carry out the biological functions in the biochemical pathway.
The cells were cultured in folate-deficient and folate-sufficient media, and proteins involved in proliferation, DNA repair, programmed cell death (apoptosis), and those linked to the transformation of cells into malignancies.
Proteins associated with all of these processes were altered, and the researchers specifically noted that proteins such as Nit2 and COMT associated with the malignant transformation had not previously been associated with low folate levels.
“This is the first study to describe how folate deficiency alters global protein expression and genomic stability in non-cancer-derived human colon cells in vitro,” wrote Duthie and co-workers.
Bonnie - this is exciting stuff. I mentioned in my State of the Nutritionist Speech back in December that utilizing proteonomic, metabolomic, and genetic assessments would give a much clearer picture of what an individual's nutritional needs may be. Here is one study that has utilized two of those techniques.

Study: Fish Oil Superior to Crestor
An Italian study found that fish oil supplements work slightly better than the cholesterol-reducing drug Crestor in helping patients with chronic heart failure. The study findings, published online Aug. 31 in the medical journal The Lancet and presented at a meeting of the European Society of Cardiology in Germany, reinforce the idea that treating patients with heart failure takes more than just drugs.
In the study, Italian researchers gave nearly 3,500 patients diagnosed with heart failure a daily prescription fish oil pill. Another group of approximately 3,500 patients received a placebo pill. Both groups were followed for four years. In the placebo group, 2,053 died of or were hospitalized for heart failure, while 1,981 people died of or were hospitalized for heart failure in the fish oil group. In parallel research, the Italian doctors gave 2,285 heart failure patients rosuvastatin (a prescription cholesterol drug sold under the brand Crestor) and 2,289 people placebo pills. These patients were also tracked for four years, and the researchers found little difference in heart failure rates between the two groups. Comparing the results of the studies—which were funded by an Italian group of pharmaceuticals including Pfizer Inc., Sigma Tau SpA and AstraZeneca PLC—the researchers concluded that fish oil is slightly more effective than Crestor.
Bonnie - This was a large, well-conducted study. If I were a long-time client who at one time had the choice of listening to me (take fish oil) or their doctor (take the med), I would be pretty angry if I had chosen the latter. Given the multitude of benefits fish oil provides besides heart health, along with the multitude of problems cholesterol meds provide, is there even a question which is the better choice?
High blood calcium tied to lethal prostate cancer
Men with elevated levels of calcium in their blood may have a much higher risk of getting fatal prostate cancer, U.S. researchers said on Wednesday.
The findings indicate that a simple blood test may identify men at high risk for the most dangerous prostate tumors, and there already are drugs available that cut calcium levels in the bloodstream, the researchers said.
They tracked 2,814 men in a government health survey in which they gave blood samples that revealed calcium levels.
The men in the top third of blood calcium levels had 2.68 times the risk of developing fatal prostate cancer later in life compared to those in the bottom third, the study found.
"If serum calcium really does increase your risk for fatal prostate cancer, that's wonderfully exciting because serum calcium levels can be changed," Gary Schwartz of Wake Forest University School of Medicine, who helped lead the study, said in a telephone interview.
"One way to think of it is to think of the tremendous advances in the control of cardiovascular disease that occur from understanding that things like serum cholesterol predict heart attack," Schwartz added.
According to the American Association for Cancer Research's journal Cancer Epidemiology, Biomarkers & Prevention, people treated for high blood calcium usually have chronic kidney disease, which is associated with low vitamin D levels. Low vitamin D levels elevate parathyroid hormone levels, Schwartz said.
Halcyon Skinner of the University of Wisconsin, who also worked on the study, said there is little relationship between calcium in the diet and blood calcium levels, so these men would not benefit from eating less food rich in calcium.
Bonnie - I still think that malabsorbed calcium via supplementation or other means can create calcification in areas such as the prostate. I would not close the book on this being a contributor.
Trans fats linked to pre-cancerous colon growths
People who ate the most trans fatty acids were more likely to have pre-cancerous growths or polyps in their colons than those who consumed the least, Dr. Lisa C. Vinikoor of the University of North Carolina in Chapel Hill and colleagues found. "These results provide further support for recommendations to limit consumption of trans-fatty acids," they conclude.

Food Makers Scrimp on Ingredients In an Effort to Fatten Their Profits
Wall Street Journal
Major food makers are quietly altering their recipes on candy, dairy products and other top-selling lines, adding fillers and substituting cheaper ingredients to cut costs amid the commodities boom.
Hershey Co. is substituting vegetable oil for a portion of the cocoa butter traditionally used in some of its chocolates. Spice maker McCormick & Co. is now supplying food companies with cheaper spices and new flavor blends, such as Mexican oregano instead of pricier Mediterranean oregano, and garlic concentrate instead of heavier (and costlier to ship) garlic cloves.
General Mills Inc. says that by reducing the number of spice and ingredient pouches in boxes of Hamburger Helper -- and by halving the number of pasta shapes used in the product line -- the company has trimmed manufacturing costs 10%. The company is also replacing pecans with less expensive walnuts in its Pillsbury Turtle cookies.
Soy protein, a low-cost meat filler long used in school-cafeteria hamburgers, is making its way into more packaged foods, says Michael Considine, an executive at Minnesota grain company CHS Inc. In the past two years, he has seen a 10% increase in the volume of soy protein the group sells to major food companies, he says.
Most of the tweaked products still cost the same for consumers, if not more. Recently, Hershey announced a price increase across most of its lines.
It's happening as food companies face pressure to raise prices to cover their own fast-rising costs. On Friday, new data showed that food companies raised prices across 35 key product categories by 7.3% over the 12-week period ending Aug. 9, according AC Nielsen. The increases are "unprecedented," Sanford Bernstein analyst Alexia Howard wrote in a note to investors.
This month, McDonald's Corp. said it's testing less expensive ways to make its $1 double cheeseburger; already, some restaurants are selling the burger with one slice of cheese instead of two. And in a Thursday interview, Burger King Holdings Inc. CEO John Chidsey said the chain is testing a smaller Whopper Jr. hamburger as it tries to overcome high ingredient costs.
Bonnie - another reason to always read labels to look for ingredient changes. in addition, stick with foods with very short labels and real ingredients.
Emotional Shopping, Eating.
Research shows that people often do get a high from shopping -- the brain releases chemicals such as dopamine or serotonin when a person is stimulated by discovering something new.
For the consumer, this serves as an important reminder that the highs from emotional shopping don't last very long -- but extra weight and credit-card bills do.
Mindful eating is the paradoxical concept that eating just a few mouthfuls can savor the experience. It sounds so simple, but it takes discipline and practice. It's a far cry from the mindless way many of us eat while walking, working or watching TV, stopping only when the plate is clean or the show is over.
The approach, which has roots in Buddhism, is being studied at several academic medical centers and the National Institutes of Health as a way to combat eating disorders.
One key aspect is to approach food nonjudgmentally. Many people bring a host of negative emotions to the table -- from guilt about blowing a diet to childhood fears of deprivation or wastefulness. Here are some tips:
· Assess how hungry you are.
· Eat slowly; savor your food.
· Take time to appreciate the food on your plate.
· Notice the colors and textures of your food.
· Put your fork down and breathe between bites.
· Notice taste satiety.
· Check back on your hunger level.
· Stop when you start to feel full.

Study finds toxins in some herbal medicines
Nearly 21% of Ayurvedic medicines — plant-based products used in India for thousands of years to promote health — actually contain lead, mercury or arsenic, according to a study in today's Journal of the American Medical Association.
Arsenic can cause cancer. Lead and mercury can damage the kidneys and brain, especially in children, says study author Robert Saper of the Boston University School of Medicine and Boston Medical Center. More than 80 people have developed lead poisoning worldwide from Ayurvedic medicines since 1978, the study notes. Symptoms include fatigue, anemia and abdominal pain.
Although Ayurvedic medications are largely used by adults to treat problems ranging from indigestion to infertility, about 4% of the 193 products that Saper tested were labeled for use in children.
Saper and his colleagues purchased all of the medicines on the Internet. In a 2004 study, he also found lead, mercury and arsenic in 20% of Ayurvedic supplements sold in Boston-area stores. About 750,000 Americans have used Ayurvedic medicine, says Michael McGuffin of the American Herbal Products Association, whose members include the makers of traditional herbal products.
Manufacturers and the owners of websites mentioned in the article say they carefully test their products for safety. Peter Bowes, owner of Seattle-based Tattva's Herbs, says his company's own tests found much lower lead levels than those listed in the study.
McGuffin notes that it may be impossible to ensure that herbal products are 100% lead-free, because even fruits, vegetables and dairy products can be contaminated with lead, which can be found in soil or water.
McGuffin notes that government and professional agencies set widely different safety standards for lead, mercury and arsenic. While most of the products in Saper's article have lead levels that exceed California's standard, only two violate the World Health Organization's standard.
Saper says the Food and Drug Administration should set maximum daily dose limits for toxic metals in dietary supplements. Although the FDA currently doesn't specify how much lead is permitted in these products, it can pull products off the market if they're found to be unsafe. The FDA, for example, banned Ayurvedic products cited in Saper's 2004 study.
McGuffin says the government and industry should seriously consider such limits: "If we know what the target is, it makes it easier to hit the target."
Bonnie - one of the reasons I have never widely recommended herbs (and never Ayruvedic herbs), is because the difficulty in consistently assessing toxicity. Unless you are a company with the resources of a Metagenics or Nature's Way, who test every ounce of raw material that comes through its doors, you are going to get tainted raw material that falls through the cracks. Because with herbs, every harvest differs in terms of toxicity, many small herb companies do not have the lab resources to test every batch. I still believe that most do a diligent job of testing for heavy metals and toxins, but you run the risk of more exposure if you take a lot of herbal remedies.
One of the main reasons you utilize the services of a health professional, especially one with expertise in the use of dietary supplements, is that we do most of the work for you in terms of finding quality, safe, and effective dietary supplements that have been used and tested for decades.

MSG Use Is Linked to Obesity
Consumption of monosodium glutamate, or MSG, the widely used food additive, may increase the likelihood of being overweight, a new study says.
Researchers studied 752 men and women in three villages in northern and southern China where most people use little commercially processed food, but where about 80 percent of people add MSG in cooking.
After controlling for body mass index, smoking, physical activity and almost two dozen measures of daily nutrient intake, they found that the one-third of people who used the most MSG were almost three times as likely to be overweight — that is, to have a body mass index over 25 — as those who used none. On average, with each 0.04-ounce daily increase in MSG intake, B.M.I. went up by 0.61.
MSG makes food taste better, which may lead people to eat more, but the researchers controlled for total energy intake so it is unlikely that that explains the finding. The mechanism for the connection, published in the August issue of Obesity, remains unclear.
Bonnie - I'll tell you what the mechanism is. MSG tricks the neurotransmitters of your brain into thinking something tastes more flavorful than it really is. This overstimulation of your brain gives you the urge to eat more than you should, thus gaining weight. Don't you wonder why you can eat so much Chinese food and be ready to eat more very soon thereafter? Also, MSG is a single amino acid (glutamine) which throws off the balance of other amino acids. It also blocks B-6 and magnesium, thus causing fluid retention and possible blood sugar imbalance.

Prostate cancer risk increased in obese men taking statins
Use of cholesterol-lowering statin drugs, especially long-term use, appears to raise the risk of prostate cancer among obese men, according to findings of a new study.
"Given the epidemic of obesity in the U.S. and the frequent use of statins, the positive association we observed raises substantial concern as to the safety of these widely prescribed agents," Dr. Janet L. Stanford of the Fred Hutchinson Cancer Research Center in Seattle and colleagues wrote in the American Journal of Epidemiology.
In a population-based, case-control study, the researchers matched 1,001 men with prostate cancer diagnosed between 2002 and 2005 with 942 age-matched cancer-free controls from King County, Washington.
No overall association was observed between the risk of prostate cancer and the current or past use of statin treatment. Duration of statin use was also not associated with prostate cancer risk.
"We also found no evidence that use of a statin was associated with risk of developing more aggressive subtypes of prostate caner," Stanford said in an interview with Reuters Health. "Overall we found no support for the current hypothesis that statin use may reduce risk of prostate cancer."
However, the results do suggest a significant increase in the risk of developing prostate cancer associated with current statin use and with longer durations of use among obese men (defined as a body mass index of 30 greater).
"Among obese men," Stanford told Reuters Health, "current use of a statin was associated with a 50 percent increase in risk of prostate cancer; and use for 5 or more years was associated with an 80 percent increase in risk of the disease; both of these risk estimates were statistically significant."
These findings warrant further investigation, she said.

Bonnie - I'd say this is a very significant statistic given that the majority of the nation is overweight or obese.

F.D.A. Allows Irradiation of Some Produce
Advocates for food safety condemned the agency’s decision and asserted that irradiation could lower nutritional value, create unsafe chemicals and ruin taste. “It’s a total cop-out,” said Patty Lovera, assistant director of Food and Water Watch. “They don’t have the resources, the authority or the political will to really protect consumers from unsafe food.”
Dr. Laura Tarantino, director of the Office of Food Additive Safety at the F.D.A., said the agency had found no serious nutritional or safety changes associated with irradiation of spinach or lettuce. “These irradiated foods are not less safe than others,” Dr. Tarantino said, “and the doses are effective in reducing the level of disease-causing micro-organisms.”
The government has long allowed food processors to irradiate beef, eggs, poultry, oysters and spices, but the market for irradiated foods is tiny because the government also requires that these foods be labeled as irradiated, labels that scare away most consumers. “People think the product is radioactive,” said Harlan Clemmons, president of Sadex, a food irradiation company based in Sioux City, Iowa. The F.D.A. is considering a proposal to weaken or change this labeling requirement, a move that Caroline Smith DeWaal, food safety director at the Center for Science in the Public Interest, opposes.
Critics say that not only does radiation make food less nutritious and potentially toxic but that the process also does not eliminate the risks of food-borne illnesses. An analysis by the Centers for Science in the Public Interest found that most outbreaks of illnesses associated with salad are caused by viruses, which are not affected by the doses of radiation approved by the F.D.A. Food-safety advocates, food producers and even farm groups agree that the government should mandate certain agricultural and processing practices that would limit the risk of all food-borne illnesses and increase the speed with which outbreaks are traced back to sources. “The agency is choosing to have a high-tech expensive solution to a problem that needs a more thorough approach and one that really starts on the farm,” Ms. Smith DeWaal of the science center said. Federal officials say they continue to study the science behind proposals to require good agricultural practices. In the meantime, irradiation could help, Dr. Tarantino of the F.D.A. said. “This is not a magic bullet,” she said. “It’s not a solution for everything. It’s one more option that people can use.”

Steve - as long as irradiating food requires a label, the consumer has the choice. However, if the FDA relaxes the irradiation label, we need to be extremely vociferous in our opposition to it.

MSG slows brain cell growth
Not bad for a teenager.
Michelle Ah-Seng is a 17-year-old high school student from Cochrane, just west of Calgary. She's also the lead researcher on a University of Calgary study that offers the first solid proof that high concentrations of MSG, an additive used to boost flavour in everything from fast food to canned soups, can stunt the growth of brain cells.
"It has been shown that (in a pregnant woman), MSG will cross through the placenta and can affect the fetus," said Ah-Seng.
"Fetuses are still developing, and their brain cells are starting to grow and starting to reach out to each other. If MSG has been inhibiting or stunting the growth, then the cells basically won't reach out to one another."
Ah-Seng is one of 22 Grade 11 students spending six weeks of their summer vacation in labs and clinics at the University of Calgary as part of the 2008 Heritage Youth Researcher Summer Program, funded by the Alberta Heritage Foundation for Medical Research.
Her project involved directly dosing brain cells culled from snails with a concentration of monosodium glutamate equal to what might commonly be found in human blood or cerebral spinal fluid after eating a meal containing the additive, such as a bag of chips. Not only did the MSG inhibit growth of the snail's brain cells, it also limited communication between them. The implications for human health aren't hard to infer.
"There's no difference between a snail brain cell and a rat or a human brain cell, only that there are fewer of them and (they're) larger," said Naweed Syed, Ah-Seng's supervisor and a neuroscientist with the Hotchkiss Brain Institute at the University of Calgary's faculty of medicine.
"This is the first unequivocal evidence, to my knowledge, that MSG has direct effect on neuronal ability. I think it's very exciting."
Ah-Seng points to previous studies that have examined the link between MSG exposure on rat fetuses and increased obesity and learning disabilities after birth, as well as links to neurogenerative disorders such as Alzheimer's and ALS.
"It's very important, especially for pregnant women or people getting into their elder ages, to be aware of how much MSG (you're) consuming," she said.
The next step, said Syed, is to get the results published in a scientific journal. Ah-Seng plans to continue her work during evenings and weekends in her last year of high school to validate the findings.
"The stuff she has done (in six weeks), I would call it equivalent to a master's degree," said Syed. "The only thing I hope is that I never have to compete with this young mind. It's absolutely incredible."
Ah-Seng said she plans to curtail her MSG consumption as much as possible. "I'm sure to be more aware of how I consume different sorts of foods, because it's everywhere," she said. "You have to check the ingredients label. It's very important to be aware of how things will affect your health."
Steve - it takes the honesty and innocence of a teenager to tell the truth!
Organic food not more nutritional
Researchers studied five different crops -- carrots, kale, mature peas, apples and potatoes -- which were cultivated both organically (without pesticides) and conventionally (with the use of pesticides) and found that there was no higher level of trace elements in the food grown organically.
Study leader Dr Susanne Bügel said: "No systematic differences between cultivation systems representing organic and conventional production methods were found across the five crops so the study does not support the belief that organically grown foodstuffs generally contain more major and trace elements than conventionally grown foodstuffs."
It should be noted that the study does not make conclusions about the comparative levels of pesticides or chemicals in conventionally and organically grown food or the health effects of consuming such chemicals.
So if organic foods aren't necessarily more nutritional, are they better for the environment?
According to the Intergovernmental Panel on Climate Change, traditional agriculture accounts for around 11 percent of global greenhouse gas emissions each year, and the nitrous oxide found in fertilizers contributes most to these emissions.
The Soil Association said that: "Overall, organic farming is better for tackling climate change than industrial agricultural methods. As well as lower average energy use, organic farming also avoids the very large nitrous oxide emissions from fertilizer manufacture."
"Additionally, organic farming builds up soil carbon, removing it from the atmosphere. Organic farming also supports more local food marketing, reducing food miles."
Bonnie - aside from the fact that studies have shown organic to be more nutrient-dense than conventional, it is amazing that the study would not take into account the negative effects of pesticides in conventional produce. That alone makes organic a better choice regardless of nutrient content. See recent postings in our blog. How do you feel about organic versus conventional? Put in a comment below.

Powerful Antacid Drugs Raise Fracture Risk
This is now the third large study finding an increased risk of such fractures in people who use these medications. This latest study, reported in the current issue of the Canadian Medical Association Journal, found the longest period of time from starting the drugs to seeing problems emerge.
Physicians and patients may need to curb their enthusiasm for prescribing proton pump inhibitors, which have surged in popularity, experts said.
"Almost all of us gastroenterologists and internists have become complacent about the use of these medications," said Dr. Felice Schnoll-Sussman, director of research at the Jay Monahan Center for Gastrointestinal Health, Weill Cornell Medical Center at New York Presbyterian Hospital in New York City. "This makes us all take a step back and look at all the patients we have on these medications and ask whether they require still being on this medication, at this dosage, at this frequency. Can we make some alterations in their dosing regimen? Can we switch them? Do they need to be on anything at all at this point?"
PPIs are powerful antacid drugs prescribed for peptic ulcer disease, gastroesophageal reflux disease (GERD) and other related conditions. Brand names include Aciphex, Nexium, Prevacid, Prilosec and Protonix. The drugs are often taken for indefinite periods of time.
The drugs work by inhibiting secretion of hydrochloric acid; this may affect calcium absorption in the small intestine.
The authors of this study, from University of Manitoba in Winnipeg, examined administrative claims data for 15,792 individuals over 50 who had had osteoporosis-related fractures of the hip, vertebra or wrist, then compared them with almost 50,000 controls.
Individuals who had used proton pump inhibitors for seven or more years had almost double the risk of an osteoporosis-related fracture. There was also a 62 percent increased risk of hip fracture after five or more years of using PPIs; the risk of hip fracture jumped to more than quadruple after seven or more years.
"Some people think, 'If I take PPIs, I can eat garbage all day long,' " Schnoll-Sussman said. "We need to tighten up on those patients. These medications are not without any kind of risk."

Recall on Coleman Natural Beef
Whole Foods Market, which is voluntarily recalling more than 1 million pounds of ground beef because of a possible E. coli outbreak in fresh ground beef it sold from June 2 to Wednesday, August 6. The beef apparently came from Coleman Natural Beef's Nebraska Beef processing plant.
At this time, no Coleman Natural Beef fresh ground beef products from the Nebraska Beef processing facility are available in any Whole Foods Market stores.
Steve - we were out of town when this occurred. It is not surprising because Coleman sold their interests to a larger supplier who had a meat processing plant that had a long history of USDA violations.
Fruit, veggies lower men's cancer risk
Men who eat more fruit and vegetables have less risk of developing a type of cancer of the esophagus, a study by a Japanese medical team said Thursday.
The study spearheaded by Japan's health ministry monitored some 39,000 men aged 45 to 74 over about eight years, during which time 116 developed the type of cancer called esophageal squamous cell carcinoma (SCC).
Esophageal SCC is a common type of cancer among Japanese men, strongly linked to smoking and drinking alcohol, according to the study led by Shoichiro Tsugane, chief of the Epidemiology and Prevention Division at Japan's National Cancer Center.
The study divided men into three groups and found that those who ate the most fruit and vegetables had nearly half the risk of developing esophageal SCC compared with the group with the least vegetable-based diet.
"An increase in consumption of total fruit and vegetables by 100 grams (3.5 ounces) per day was associated with an 11 percent decrease in the incidence of esophageal SCC," the researchers said in a statement.
The study concluded that vegetables, especially the so-called cruciferous family of vegetables that includes radishes and cabbages, may help prevent esophageal SCC.
A diet rich in fruit and vegetables would lower the risk of developing this type of cancer to nearly one-third, even among men who smoke and drink, it said.
But the study warned that fruits and veggies were no substitute for the health benefits of quitting smoking or drinking.
A scientific study at Britain's Institute of Food Research showed last month that men who ate more broccoli, one of the cruciferous vegetables, reduced their risk of prostate cancer and other chronic diseases.
Steve - while it is no secret that fruits and veggies prevent cancer, it can't hurt to see it reaffirmed with continuous research.
Breakfast Eggs Keep Folks on Diet
Their two-month study of overweight or obese adults, ages 25 to 60, found that those who ate two eggs for breakfast as part of a calorie-reduced diet lost 65 percent more weight, had a 61 percent greater reduction in body mass index, and had higher energy levels than those who ate bagels for breakfast.
Blood levels of HDL ("good") and LDL ("bad") cholesterol, as well as triglycerides, remained the same in both groups.
"People have a hard time adhering to diets, and our research shows that choosing eggs for breakfast can dramatically improve the success of a weight loss plan. Apparently, the increased satiety and energy due to eggs helps people better comply with a reduced-calorie diet," lead researcher Nikhil V. Dhurandhar said in an Egg Nutrition news release. Dhurandhar is an associate professor in the laboratory of infection and obesity at Pennington Biomedical Research Center, a campus of the Louisiana State University system,
The study, funded by the industry-affiliated Egg Nutrition Center, was published online last week in the International Journal of Obesity.
Steve - please consider who funded the study. The only reason we published it is to reaffirm the importance of a balanced breakfast, especially one tha includes lean protein sources.

Stress can make allergies worse
In an experiment conducted by Kiecolt-Glaser and colleagues, 28 men and women with a history of hay fever and seasonal allergies but not asthma were given a battery of skin tests and put through a number of stressful activities, such as giving a videotaped speech before a panel of experts and solving math problems without pen or paper. Basically, she said, "we bring people into the laboratory and stress them."The result: "Folks who are more anxious had bigger (allergic) responses during stress," she said. "Even the day after stress, for more anxious persons, you see persistence of allergic symptoms." And allergy medications, such as antihistamines, have little or no effect on the late-phase responses, she said.
In other stress research to be presented to the APA, Herbert Benson, a physician and director emeritus of the Benson-Henry Institute for Mind Body Medicine at Massachusetts General Hospital, on Friday will explain how repetitious exercises that clear the mind of everyday thoughts, such as yoga and prayer, evoke what he terms the "relaxation response" and reduce psychological distress. His new work compared 19 adults who regularly engaged in activities that evoked the relaxation response to 19 who did not and found, through blood tests, differences in their white cell activity, which affects stress levels.In a second part of the investigation, 20 people who hadn't tried the practice were assigned to do it for eight weeks. They developed the same changes as those who evoked the relaxation response regularly."This is firm proof that the mind can affect the body in a therapeutic way," Benson says. "By doing repetition and disregarding other thoughts, it brings about changes in the body."

Bonnie - I wholeheartedly agree with this research. While the studies are small in stature, they reaffirm what I have believed for years. This is why finding a stress-relieving mechanism is an essential tool for anyone's wellness plan.
Antibiotics are unlikely to help sinusitis
Sinus infections are among the most common and aggravating medical conditions, diagnosed in around 31 million Americans each year. And for most patients, treatment has long included an antibiotic.
Now, medical experts are pushing for a less-aggressive approach. Around 21 percent of antibiotic prescriptions for adults in the U.S. are for sinusitis, even though studies show the drugs often do little or no good. Short-term sinusitis can be caused by either a bacterial infection, which may respond to treatment with antibiotics, or a viral infection, which doesn't. Doctors believe the overwhelming majority of cases begin as viral infections, and less than 2 percent of those turn into bacterial infections.
The American Academy of Otolaryngology - Head and Neck Surgery, which represents ear, nose and throat specialists, issued new guidelines last year for treating sinusitis. Among these: Doctors generally should wait 10 days before even considering an antibiotic. If the sinus sufferer is feeling better by then, the bug is almost surely a virus, and antibiotics would be of no use.
But if the problem lasts more than 10 days, chances are good it is bacterial. At this point, if the patient's illness is relatively mild, the guidelines leave it up to the doctor to decide between prescribing an antibiotic or monitoring the patient for as much as another week.
Some patients, and their doctors, might not be willing to wait. Keisha Herbin Smith knew what she wanted when she called her doctor's office last month about symptoms including congestion, a headache and a runny nose. Ms. Herbin Smith, a 30-year-old research coordinator from Woodbridge, Va., asked the nurse for an antibiotic to head off a full-blown sinus infection, so it wouldn't ruin a long-planned weekend at the beach. An antibiotic "just makes you feel better sooner," says Herbin Smith, who got her prescription and enjoyed her vacation, and later went to see her doctor when she returned.
The drugs have drawbacks. The analysis's lead author, Richard Rosenfeld, found that 25 percent of sinusitis patients who got antibiotics had side effect such as gastrointestinal problems, skin rashes or headaches. Widespread use of antibiotics is also blamed for the emergence of resistant bacteria that don't respond to traditional drugs.Other medical authorities want to go even further than the academy's guidelines to minimize the use of antibiotics in treating sinusitis. An analysis by international researchers published in the Lancet medical journal in March said the drugs "are not justified even if a patient reports symptoms for longer than seven to 10 days." That's because the way doctors typically diagnose sinusitis, based on symptoms, isn't typically enough to determine which patients will benefit from antibiotics, the authors concluded.
Bonnie - we have discussed the overuse of antibiotics for years. Here is yet another case of it. Mayo Clinic research also determined that many sinus infections are fungal in nature (i.e. yeast overgrowth). Antibiotics actually worsen this situation making the fungi stronger and more antibiotic resistant.

FDA: BPA in Plastic Bottles Isn’t a Health Hazard
Courtesy of Wall Street Journal
Bisphenol A, a chemical that shows up in some baby bottles, food can linings and hard plastic water bottles, just got a vote of confidence from the FDA.
“FDA has concluded that an adequate margin of safety exists for BPA at current levels of exposure from food contact uses,” said an FDA draft assessment released Friday.
Earlier this year, a draft report from another federal agency concluded that “[T]he possibility that bisphenol A may alter human development cannot be dismissed.”
That was part of what prompted Wal-Mart, among others, to say it would stop selling baby bottles that contain the chemical. And California is now considering a bill that would ban the substance in food and drink containers made for infants.
The FDA assessment was released in advance of a September meeting where a panel of experts will discuss the subject.
In his weekly message posted on the FDA’s Web site, FDA Commish Andrew von Eschenbach wrote that “science creates these products and science must inform us of their risks. With regard to BPA thus far, the science FDA has reviewed does not justify recommending that anyone discontinue using these products.”
But environmental groups were critical of FDA’s analysis, which they argued were based on studies funded by industry. “It’s ironic FDA would choose to ignore dozens of studies funded by (the National Institutes of Health) — this country’s best scientists — and instead rely on flawed studies from industry,” Pete Myers, chief scientist for Environmental Health Sciences, told the AP.

Monsanto Looks to Sell Dairy Hormone Business
Concerns have been fueled by the refusal of many countries, including Canada and members of the European Union, to permit the use of the hormone. “I think they saw the handwriting on the wall and gave up,” said Andrew Kimbrell, executive director of the Center for Food Safety, a consumer advocacy group based in Washington. “It’s a major victory for consumers.”
Bonnie - yes! yes! yes! A long, drawn-out victory for the consumer! Along with trans fats, this has been one of my longest public health battles of all. My colleague and a mentor, Dr. Sam Epstein of U of Chicago, must be very happy right now. He is been most outspoken over this substance for decades. Hats off to you Sam.
Now, the question becomes, who are they going to sell it to because who would want to buy it?

Oxygen therapies may ease headache pain
In a review of nine small clinical trials, the researchers found that hyperbaric oxygen therapy showed promise for halting pain during migraine attacks. A similar treatment -- normobaric, or normal-pressure, oxygen therapy -- eased pain in people suffering from cluster headaches.
The findings are published in the Cochrane Library, a publication of the Cochrane Collaboration, an international organization that evaluates medical research.
Hyperbaric oxygen therapy involves breathing pure oxygen in a sealed, pressurized chamber. With normobaric oxygen therapy, patients breathe pure oxygen from a portable unit under normal conditions.
Normal-pressure oxygen has long been used for severe headache pain, and there is some evidence that hyperbaric oxygen could be helpful, but few controlled clinical trials have evaluated the therapies.
None of the two forms of oxygen therapy prevented future headache attacks, however, lead researcher Dr. Michael H. Bennett, of Prince of Wales Hospital in Randwick, Australia, told Reuters Health.
Bonnie - for those looking for another complementary, non-drug therapy, it is certainly worth a try.
Psychiatrists embrace pill power

Psychiatrists in the United States are trading in the analysis couch for a prescription pad, according to a study released on Monday that found fewer psychiatrists offer psychotherapy.
The shift to briefer visits for medication management, reported in the Archives of General Psychiatry, appears to be linked to better psychiatric drugs and pressure from managed care companies, which offer richer financial incentives for brief office visits.
"Psychiatrists get more for three, 15-minute medication management visits than for one 45 minute psychotherapy visit," said Dr. Ramin Mojtabai of Johns Hopkins University in Baltimore and formerly of Beth Israel Medical Center in New York, where he did the research.
Various forms of psychotherapy, either alone or in combination with medications, are recommended to treat depression, post-traumatic stress disorder, bipolar disorder and other psychiatric illnesses.
Yet Mojtabai and colleagues, who analyzed data from national surveys of office-based psychiatrist visits from 1996 through 2005, found a significant drop in the number of office-based psychiatrists providing psychotherapy.
He said just 29 percent of office-based visits to psychiatrists involved psychotherapy in 2004-5, down from 44 percent in 1996-97.
One major impact is that patients who need to receive psychotherapy must get it from other professionals, if they get it at all, Mojtabai said in a telephone interview.
That can result in disjointed service, in which a patient sees a psychologist or social worker for therapy and a psychiatrist or a general physician for drugs.
Bonnie - a sad state of affairs, but not surprising in this day and age.
Superfruits disturb the five-a-day balance
The popularity of exotic fruits has contributed to increasing fruit and vegetable consumption, but the consequences of so-called superfruits muscling traditional products out of the diet is evident.
According to a new report from Datamonitor average consumption of fruit and veg has risen since the five-a-day campaign began. Parallel to this, however, has been a rise in interest in exotic or ‘super’ fruits that are high in antioxidants, like goji, pomegranate, and acai.
Datamonitor indicated that 18 per cent of customers were more inclined to substitute superfruits for ordinary fruit and veg. The perception is that, by dint of antioxiants alone, superfruits are better than traditional, every day fruits like apples.
But if consumers eat just superfruits, they risk missing out of the important nutrients that are found in other, more mundane produce. In fact, the five-a-day slogan is accompanied by advice to ensure a broad variety of different fruit and vegetables are consumed.
Moreover, consumers could assume that because they have eaten, say, goji berries today, a consumer does not need to eat the other four servings of fruit and veg.
Steve - consumers should treat superfruits as a supplement to their daily fruit and vegetable intake, not in place of.
MDs urged to quit prostate screens in elderly men
Courtesy of Associated Press
Doctors should stop routine prostate cancer screening of men over 75 because there is more evidence of harm than benefit, a federal task force advised Monday in a new blow to a much scrutinized medical test.
The U.S. Preventive Services Task Force, which made the recommendation, reported finding evidence that the benefits of treatment based on routine screening of this age group "are small to none." However, treatment often causes "moderate-to-substantial harms," including erectile dysfunction and bladder control and bowel problems, the task force said.
The new guidance is the first update by the task force on prostate cancer screening since 2002. The last report on the subject from this panel of experts, which sets the nation's primary care standards, concluded there was insufficient evidence to recommend prostate screening for men of all ages.
In recent years, there has been a growing debate about the value of the somewhat imprecise PSA test to detect cancer, as well as the value of treating most prostate cancers. A number of experts contend patients are being overtreated.
Earlier this year, a study found that older men who already had early-stage prostate cancer were not taking a big risk by not treating it right away. The vast majority were alive 10 years later without significantly worrying symptoms or had died of other causes.
Prostate cancer treatments are tough, especially on older men. Some doctors instead recommend "watchful waiting" to monitor signs of the disease and treat only if they worsen, but smaller studies give conflicting views of the safety of that approach.
The new guidelines from the Preventive Services Task Force were published in this month's Annals of Internal Medicine.
Bonnie - it took them only 22 years to realize this.

The Overflowing American Dinner Plate
In 1970, the average American ate about 16.4 pounds of food a week, or 2.3 pounds daily. By 2006, the average intake grew by an additional 1.8 pounds a week.
Among other things, that's an extra half pound of fat weekly - mostly from oils and shortening. That doesn't count the fat in the extra quarter pound of meat Americans now eat every seven days. Those fats were somewhat offset by a steep drop in dairy consumption, the only major food group to have a decline, primarily in milk drinking. (But we do love our cheese. More and more of it.)
This portrait of the raw ingredients of the American diet is based on what the Agriculture Department calls "food availability" - the amount of food produced for the average American consumer. The data are adjusted for food losses (waste on farms; in processing and transportation; and in stores, restaurants and homes) to provide a close approximation of what individuals eat. (The most recent year for which data are available is 2006.)
The numbers don't reveal how much grain went into bread versus cookies, or how many chicken breasts became chicken nuggets. But the overall increase in eating does suggest a link with the rise in Americans' weight over the same period. According to the Centers for Disease Control, 15 percent of adults age 20 to 74 were obese by 1980. By 2007, that had more than doubled.

Study Explains How Cranberries Prevent Urinary Infections
Their study, published in the current issue of Colloids and Surfaces: B, shows that the juice changes the thermodynamic properties of bacteria in the urinary tract to form an energy barrier that prevents infections from developing.
The research team found that when bacteria with hair-like projections known as fimbriae, which is present on virulent bacteria that cause urinary tract infections, is exposed to even low concentrations of cranberry juice that energy levels increased to levels that made it difficult for the bacteria attach to a cell.
"Our results show that, at least for urinary tract infections, cranberry juice targets the right bacteria -- those that cause disease -- but has no effect on non-pathogenic organisms, suggesting that cranberry juice will not disrupt bacteria that are part of the normal flora in the gut," Terri Camesano, an associate professor of chemical engineering at WPI, said in a university news release. "We have also shown that this effect occurs at concentrations of cranberry juice that are comparable to levels we would expect to find in the urinary tract."
Camesano said that unpublished work also shows cranberry juice has potent effects on disease-causing bacteria, but that the effect is temporary. "This suggests that to realize the antibacterial benefits of cranberry, one must consume cranberry juice regularly, perhaps daily," she said.
Steve - a better option than cranberry juice (too much sugar) would be Solaray Cranactin capsules or liquid concentrate with stevia.
Flu jabs 'can't stop pneumonia'
One of the main benefits of flu jabs for the elderly - protection against pneumonia - may not exist, US scientists have claimed. They say the risk of pneumonia for older people stayed the same, whether they received the jab or not. The study, published in The Lancet journal, looked at pneumonia rates among thousands of vaccinated and unvaccinated people. The latest research followed 3,500 people through three flu seasons to see if it made any difference, and while slightly fewer vaccinated patients were diagnosed with pneumonia, the difference was not statistically significant.

Potassium may help lower blood pressure
Research shows that boosting levels of potassium in the diet may lower a person's risk of developing high blood pressure and may decrease blood pressure in people who already have "hypertension," according to a special supplement to The Journal of Clinical Hypertension this month. Dr. Mark C. Houston, from Vanderbilt University School of Medicine and Dr. Karen J. Harper from Harper Medical Communications, Inc. in Nashville, also point out that a healthy intake of potassium is thought to be one reason why vegetarians and isolated populations have a very low incidence of heart disease. In isolated societies consuming diets low in sodium and high in fruits and vegetables, which have and therefore high levels of potassium, hypertension affects only 1 percent of the population, they note. In contrast, in industrialized societies, where people consume diets high in processed foods and large amounts of dietary sodium 1 in 3 persons have hypertension. The typical American diet contains about double the sodium and half the potassium that is currently recommended in dietary guidelines. Low potassium intake is thought to contribute to the prevalence of high blood pressure in Americans. Based on their review of published studies on the topic, Houston and Harper say if Americans were to boost their potassium intake, the number of adults with known high blood pressure could fall by more than 10 percent. Some studies also show that diets containing at least 500 to 1,000 milligrams magnesium daily and more than 800 milligrams of calcium daily may help lower blood pressure and the risk of developing high blood pressure. "A high intake of these minerals through increased consumption of fruits and vegetables may improve blood pressure levels and reduce coronary heart disease and stroke," Houston and Harper conclude.

FDA survey supports low lead levels in supplements
"These safe/tolerable levels are referred to as the provisional total tolerable intake levels (PTTI) and are 6, 15, 25, and 75 micrograms of lead per day for young children, older children, pregnant or lactating women, and adult women, respectively," wrote the authors in the Journal of Agricultural and Food Chemistry.
"Estimates of lead exposures were below the PTTI levels for the four population groups," they added.
"Most samples were extremely low in lead, with a median value of 0.160 mg/kg and only four samples exceeding 1 mg/kg," wrote the scientists.
The full list of supplements and lead mass fraction and exposure results is available free of charge at the American Chemical Society's website.

Vitamin C-rich diet may slash diabetes risk
Researchers analyzed dietary patterns using a semi-quantitative food frequency questionnaire (FFQ) amongst the participants of the European Prospective Investigation of Cancer - Norfolk. The men and women had an average age of 58.4 at the start of the study, and women made up two-thirds of the study population. Over 12 years of follow-up 735 incident cases of diabetes were diagnosed.
Correlating blood levels of vitamin C and diabetes, the researchers found that men and women with the highest blood levels (at least 1.10 and 1.29 mg/dL, respectively) had a 62 per cent reduction in their risk of developing type-2 diabetes, compared to men and women with the lowest blood levels (less than 0.56 and 0.77 mg/dL, respectively).
Moreover, men and women with the highest fruit and vegetable intake (459 and 550 grams per day, respectively) had a 22 per cent reduction in their risk of developing type-2 diabetes, compared to men and women with the lowest fruit and vegetable intake (289 and 382 grams per day, respectively).
Steve - what is so shocking about this study is the advanced age of the subjects. It is very unusual to see such drastic reductions in a chronic condition like Type 2 from a single nutrient. However, other variables need be factored in, such as the subjects with the highest vitamin C levels most likely keep themselves healthier by eating more fruits and vegetables.
