A recent study aimed to examine the relationship between cognitive decline, MRI changes, and levels of B12 and other biochemical markers of B12 deficiency, namely serum homocysteine and methylmalonic acid (MMA). In a study of 6158 persons, both homocysteine and MMA were significantly associated with poorer cognitive testing across multiple domains; B12 levels demonstrated no such association.

Although they understand that some people’s immune systems resist the virus, they still don’t know how or why that happens. There is a behind the scene active immune response even when you don’t get sick. What they found were differences in their biological metabolism and gene expression. These differences had to do with antioxidants.
Moreover, the researchers claim it is certainly possible that people who resisted the flu virus had very high levels of antioxidant precursors in their blood, and this may what protected them, but they cannot say that because they don’t know.
In a commentary published in Journal of Pediatrics, Eric Hassell, MD, a pediatric gastroenterologist, warns that the use of acid-suppressing medications to babies under 1 year old has skyrocketed. One large study in the U.S. found a 16-fold increase in the number of prescriptions for a kid-friendly liquid form of acid-suppressing drugs between 1999 and 2004. Despite this recent spike in prescriptions, Hassall argues that the vast majority of infants don't have gastroesophageal reflux disease (GERD), which is what these drugs are meant to treat. He suggests that a baby's inconsolable crying and spitting up, which are separate symptoms, have become combined into a diagnosis of acid-reflux disease by some pediatricians.
But this spitting up likely isn't "acid reflux" because infants have frequent feedings that tend to buffer stomach acid. Most reflux is physiological. In most cases, it's not the spitting up that should be treated. The real issue is the unexplained crying. Some moms and dads put a lot of pressure on pediatricians to "do something" to help their hard-to-soothe infants. It's sometimes easier and quicker for a doctor to write a prescription instead of taking the time to explain what parents can try in place of drugs. He suspects that both parents and pediatricians are unaware of the extent to which acid-reducing drugs are being overprescribed or of their potential side effects if used long-term.
According to Esther Israel, MD, a pediatric gastroenterologist, "Gastroesophageal reflux is not a disease in infants. It's a normal physiological response that babies often outgrow." She says that before turning to medications, there are a lot of things that can be done from a behavioral perspective. These include soothing-type activities, such as rocking or patting the newborn in a quiet place. Dietary approaches such as switching from a milk protein-containing formula to a soy-based or hydrolyzed one may also make a difference. If a mother is breastfeeding, she can try eliminating milk products from her diet to see how her baby responds. If colic is a concern, infants usually outgrow it in their first three to four months of life.
Cow's Milk Usually to Blame
As the piece above alludes, there are times when infant formula needs to be changed. A study in the October issue of Gut Liver explains that in children who actually do have Gastroesophageal Reflux Disease, cow's milk allergy (CMA) is the major culprit. 81 children with actual GERD were enrolled in the study. All subjects received omeprazole for 4 weeks after the initial evaluation. Empirical elimination of cow's milk from the diet was started for the patients who did not respond to the omeprazole treatment.
Cow's milk was eliminated from the diets of the remaining 27 patients who did not respond to treatment. All signs and symptoms of GERD were resolved in this group after a 4 week elimination of cow's milk from the diet. A diagnosis of CMA was considered in one third of the pediatric cases with signs and symptoms of GERD. This finding shows that CMA can mimic or aggravate all signs and symptoms of severe GERD during infancy.
According to the study, many clinical guidelines for cardiovascular disease (CVD) prevention contain risk estimation charts/calculators. These have shown a tendency to overestimate risk, which indicates that there might be theoretical flaws in the algorithms. Total cholesterol is a frequently used variable in the risk estimates. Some studies indicate that the predictive properties of cholesterol might not be as straightforward as widely assumed. The researchers aim was to document the strength and validity of total cholesterol as a risk factor for mortality in a well-defined, general Norwegian population without known CVD at baseline.
They assessed the association of total serum cholesterol with total mortality, as well as mortality from CVD and ischaemic heart disease (IHD). The study population comprised 52,087 Norwegians, aged 20–74, who were followed-up on cause-specific mortality for 10 years (510 297 person-years in total).
Among women, higher cholesterol meant lower all-cause mortality as well as CVD mortality. Among men, the association of cholesterol with mortality from CVD and in total followed a ‘U-shaped’ pattern.
The study provides an updated epidemiological indication of possible errors in the CVD risk algorithms of many clinical guidelines. If the findings are generalizable, clinical and public health recommendations regarding the ‘dangers’ of cholesterol should be revised. This is especially true for women, for whom moderately elevated cholesterol
(by current standards) may prove to be not only harmless but even beneficial.

- 1,080 from supplements (over half the US population, 154 million, take supplements)
- 526,527 from prescription drugs. For every adverse event from supplements, there are 488 adverse events from prescription drugs.
The status of vitamins A, E and C was generally satisfactory. Eighty-eight percent and 42% of participants were deficient in vitamins D and K, respectively, as were 29% for B6; up to 10% of participants were deficient in vitamins B1, B2, B12 and folate. A considerable percentage of participants was, however, at risk for vitamin deficiencies (vitamins B1, B6, B12, folate: 20–30%, vitamin B2: 60%). Except for vitamins A and K, regular intake of supplements had a significant positive influence on vitamin levels.
These results indicate that use of supplements significantly improved the status of several vitamins in elderly people. Due to age-related problems concerning the intake and digestion of nutrients, a moderate, regular supplementation might be a useful option for older people who are otherwise unable to satisfy their micronutrient requirements.

Bonnie - many of you who know me can attest to the fact that I have never liked fertility drugs. However, it is not my place to insist that my clients shun them. If you have ever worked with couples who cannot conceive, it is heartbreaking. I always insist that couples exhaust every other option before they resort to taking fertility drugs. I have had many cases where dietary and lifestyle changes is all that is needed. In cases where diet and lifestyle is not enough, I still work with clients to make sure they are nutritionally optimal to handle the effects of the drugs.
Will I be surprised if in the next decade we see an large uptick in female cancers from fertility drugs? Unfortunately, not. Can I blame these individuals for taking them? Unfortunately, not. What I can blame is the appalling environmental, diet, and lifestyle habits that has driven so many to resort to these drugs.
A Health Service Research study says your doc could be pulling a fast one. The researchers set out to examine personal use of complementary and alternative medicine (CAM) among U.S. health care workers. The researchers examined a sample of 14,329 employed adults. They discovered that health care workers are more likely than the general population to use CAM. Among health care workers, health care providers are more likely to use CAM than other occupations.
Data from the National Health and Nutrition Examination Surveys, 2005–2008
- Eleven percent of Americans aged 12 years and over take antidepressant medication.
- Overall, females are 2½ times as likely to take antidepressant medication as males. Twenty-three percent of women aged 40–59 take antidepressants, more than in any other age-sex group.
- Non-Hispanic white persons are more likely to take antidepressants than are non-Hispanic black and Mexican-American persons.
- About one-third of persons with severe depressive symptoms take antidepressant medication.
- More than 60% of Americans taking antidepressant medication have taken it for 2 years or longer, with 14% having taken the medication for 10 years or more.
- Less than one-third of Americans taking one antidepressant medication and less than one-half of those taking multiple antidepressants have seen a mental health professional in the past year.
Antidepressants were the third most common prescription drug taken by Americans of all ages in 2005–2008 and the most frequently used by persons aged 18–44 years. From 1988–1994 through 2005–2008, the rate of antidepressant use in the United States among all ages increased nearly 400%.
This data brief discusses all antidepressants taken, regardless of the reason for use. While the majority of antidepressants are taken to treat depression, antidepressants also can be taken to treat anxiety disorders, for example.

But in every other result, water drinkers outshines the diet beverage drinkers, according to data presented at the Obesity Society's annual meeting.
The two intervention groups were instructed to replace at least 200 kcal of caloric beverages every day with either water or diet drinks. At six months, they said, there was no difference in absolute weight between the two study groups -- but those who drank water had a significantly greater improvement in fasting glucose and a trend toward a lower diastolic blood pressure compared to the control group.
At three months into the trial, participants consuming diet drinks were more likely to be consuming more calories in general compared to the water drinkers.
After six months, the diet beverage drinkers were more likely to consume non-sugar carbohydrates compared to the water group.
Diet beverage drinkers were also more likely to eat desserts, sweeteners and breads at three months, compared to the water drinkers.
There have been several recent studies actually linking diet beverages to weight GAIN, so the weight-loss percentage in this study is questionable as it is.
Let there be no doubt, however: water far outshines diet beverages in every way.
In PLoS One, researchers found that better diet quality was associated with better mental health in adolescents cross-sectionally and over time. Importantly, these findings suggest it may be possible to prevent teenage depression by ensuring adolescent diets are sufficiently nutritious, and improving diet quality may help treat depressive symptoms in this population.
Three quarters of lifetime psychiatric disorders emerge in adolescence or early adulthood, and a recent survey showed more than 22% of adolescents aged 13 to 18 years had already experienced a clinically significant mental health problem.
A healthy diet was defined as one that included fruit and vegetables as "core food groups" and included both 2 or more servings of fruit per day and 4 or more servings of vegetables, as well as general avoidance of processed foods including chips, fried foods, chocolate, sweets, and ice cream. An unhealthy diet was high in snack and processed foods. The investigators found that higher healthy diet scores at baseline predicted higher (better) Pediatric Quality of Life Inventory scores at follow-up, whereas higher "unhealthy" baseline scores predicted poorer mental health. Adolescents who improved the quality of their diets also experienced improved mental health. In contrast, those whose dietary quality deteriorated experience a worsening of their mental health status. During the 2-year study period, adolescents who improved the quality of their diets also experienced improved mental health. In contrast, those whose dietary quality deteriorated experience a worsening of the
These findings come directly on the heels of another study by the same researchers in Psychosomatic Medicine, revealing a significant link between better-quality diets and improved mental health outcomes, and specifically depression and anxiety, in a cohort of adult men and women. Individuals with better quality diets were less likely to be depressed, whereas a higher intake of processed and unhealthy foods was associated with increased anxiety.
"Dear Members and Friends of the College,
Many members of the College have expressed that they wish the College to be a strong voice for unbiased nutrition science. On September 28, 2011, the Board of Directors adopted a policy that the College shall accept no corporate funding. The policy states: "The American College of Nutrition accepts no funding from for-profit corporations. This policy fosters our mission and our ability to advance unbiased science without compromise." We are proud to have taken this important step as a scientific body, and believe this will strengthen even further the voice of the College as an advocate for the crucial role of rigorous, unbiased nutrition science in improving human health."
Bonnie - I never bought into the hoodia hype. The data, as well as waning consumer demand, is bearing this out.

Do vitamins increase the risk of death? According to one recent medical study, the conclusion may be yes. However, does the data really support the conclusions or are the results being exaggerated? In my opinion, the conclusions of the study are a real stretch based on the structure of the study itself.
This study, published in the Archives of Internal Medicine, is not a double blind, placebo controlled, prospective study. It is part of a larger study and concluded that elderly women who took vitamins had a slightly increased risk of death compared with those who did not. In contrast, this study also suggested that calcium, as a supplement, was associated with a 3.8 percent reduced risk of death.
The data was part of the very large Iowa Women’s Health Study consisting of 41,836 postmenopausal women, ages 55 to 69 who filled out questionnaires in 1987, 1997 and 2004. The questionnaires covered many aspects of health including vitamin use. Although these studies are essential because they provide a large amount of data, correlation does not prove causation. This means that self-reported data is notoriously unreliable, and since there are no controls, the results are far from conclusive. These types of studies are usually the foundation for further, well-designed and controlled studies.
There are a number of factors that can affect the skew, the statistics and the conclusions. It may be possible that those women who have more illnesses and are at a greater risk of death simply use more. Medication use also is important. Even safe over-the-counter pain medications can increase the risk (small but real) of serious hospitalization and death. In addition, physical activity, diet and habits like smoking and alcohol abuse all can affect the outcome.
Among health care professionals, whether vitamins are helpful, harmful or a waste of money is very controversial. However there are, literally, thousands of well-designed, prospective studies worldwide demonstrating the benefits of vitamins for heart disease, diabetes, high blood pressure, pain, Alzheimer’s disease, etc. It is important that accurate information is available to the general public and health care community.
Fortunately, there are now a number of credible resources for accurate information about vitamin use. One of these sources is the Natural Health Research Institute (I hold an unpaid position on the scientific advisory board). The institute is described as “an independent, nonprofit organization that supports science-based research on natural health and wellness.” Its goal is to inform people about the benefits of good food, supplements (if needed) and healthy lifestyles.
The institute is having its sixth annual scientific symposium in Schaumburg on Friday, Oct. 28. The symposium is open to the public and the speakers are internationally recognized experts in the area of vitamins and health. The topic is “Measuring the efficacy, safety and cost savings of dietary supplements.” More information can be found on their website: naturalhealthresearch.org/nhri.

Here are some ideas to make Halloween a bit healthier:
- Trick-or-treating: what to do with all the candy! If you are an enterprising parent or child, turn that candy into cash! We have used the following method for two generations of Minsky children. Tell your child that for every piece of candy, they will receive a nickel or dime (your choice). When you explain to them what it can add up to, and they can use the $ to spend as they wish, they usually jump at the chance. Don't forget to let them know that they can still eat a piece or two of their spoils (if interested).
- School Parties or Events: we always recommend kids eating healthy snacks instead of candy. Although, if your child is going to eat candy, try to accompany them with their own candy (free of artificial ingredients and hydrogenated fats) and always, ALWAYS accompany it with a healthy fat (like nuts/seeds) or lean protein (jerky, deli turkey, etc.). This will protect against blood sugar highs and lows.
- Handing Out Candy: do your visiting trick-or-treaters a favor. If you are going to pass out candy, try to offer the best of the worst (free of artificial sweetners, artificial flavors, artificial colors, hydrogenated or partially-hydrogenated fats). For instance, Whole Foods has on sale Yummy Earth Organic Gummy Bears and Lollipops, Wee Glee Gum, as well as, Endangered Species Dark Chocolate Squares.
Or better yet, do not hand out candy at all. You can also hand out pretzels, seeds, trail mix, raisins, or other dried fruit.
Non-food items like a pencil, eraser, stickers, trading cards, toothbrushes, or coins are great ideas.
- Eat a Meal or Big Snack Before Halloween Parties/Events: this way, your kids will be less apt to gorge on the junk because they are already satiated.
- What to Do With the Leftover Candy? Adults, do not consume it. It's bad for you too and does not set a good example. Do not give it away to neighbors or charity (why would you want others to consume junk). Throw it in the trash!
A BMJ study aimed to evaluate the association of chocolate consumption with the risk of developing cardiometabolic disorders. The primary outcome was cardiometabolic disorders, including cardiovascular disease (coronary heart disease and stroke), diabetes, and metabolic syndrome. The study assessed the risk of developing cardiometabolic disorders by comparing the highest and lowest level of chocolate consumption.
There was a beneficial association between higher levels of chocolate consumption and the risk of cardiometabolic disorders. The highest levels of chocolate consumption were associated with a 37% reduction in cardiovascular disease and a 29% reduction in stroke compared with the lowest levels.

"Researchers assessed the use of vitamin and mineral supplements in relation to total mortality in 38 772 older women in the Iowa Women's Health Study; mean age was 61.6 years at baseline in 1986. Supplement use was self-reported in 1986, 1997, and 2004 questionnaires. Of the 15 594 deaths (only 40% of the sample size because they were unable to obtain the death records of many of the subjects) identified through the State Health Registry of Iowa, the a multivariable adjusted proportional hazards regression model, the use of multivitamins absolute risk, vitamin B6, folic acid, iron, magnesium, zinc, and copper were associated with increased risk of total mortality when compared with corresponding nonuse (the risk being the strongest with supplement iron).
Bonnie & Steve - not surprisingly, the media failed to mention how the supplements positively affected the subjects. We thought we would mention it. Here is a direct quote from the study:
"Compared with nonusers, supplement users had a LOWER prevalence of diabetes mellitus, high blood pressure, and smoking status; a lower BMI and waist to hip ratio; and were less likely to live on a farm. Supplement users had higher educational level, were more physically active, and were more likely to use estrogen replacement therapy. Also, supplement users were more likely to have lower intake of energy, total fat, and monounsaturated fatty acids, saturated fatty acids, and to have higher intakes of protein, carbohydrates, polyunsaturated fatty acids, alcohol, whole grain products, fruits, and vegetables."
So why was there no mention about supplemental benefit for many of these lifestyle factors? The lead researcher of the study has published negative, questionable research on supplements before, only to be proven wrong years later (i.e. beta carotene and vitamin A).
There were several factors in the supplement group that needed to be addressed: taking synthetic estrogen, not eating enough monounstaurated fat, eating too much polyunsaturated (inflammatory) fat, and eating too many carbs. All of these factors contribute to heart disease and cancer. It is fascinating to note that when researchers excluded supplement users who had CVD and diabetes, the supplements did not show any adverse affect on mortality. So, in essence, the supplement users were better off than the nonusers based upon the aforementioned lifestyle factors.
What does this say? That researchers can extrapolate data however they see fit, especially from a questionnaire-based study. For example, we can extrapolate from this study that if you looked solely at supplement users who were most likely to take synthetic estrogen, most likely to eat inflammatory fats and carbs, and who ate the least amount of monounsaturated fats, we guarantee that mortality risk would skyrocket. Even more egregious is that the researchers did not remove subjects who used synthetic estrogen, which has been linked to a greatly increased risk of CVD and cancer. This should be enough to discredit the study outright.
One other issue: we do not know what brands of supplements these subjects were on. If many of them were on brands such as Centrum, who knows. We do not consider those healthful supplements.
The media did get what it needed, however. Any time they can jump on a study discrediting supplements, they are all over it.
Statement by Duffy MacKay, N.D., vice president, scientific and regulatory affairs, Council for Responsible Nutrition: “Dietary supplements are used by more than 150 million Americans in combination with other healthy lifestyle habits such as trying to eat a healthy diet and exercising regularly. Research consistently shows that dietary supplement users are higher educated, have higher income levels, and are more likely to engage in other healthy practices than non-supplement users. This study did not discount those facts, and expressly noted that supplement users were more likely to be physically active, more likely to have a lower BMI and waist-to-hip ratio, and have a lower prevalence of smoking, high blood pressure, and diabetes mellitus. The authors note in their article that ‘…dietary supplements are commonly taken to prevent chronic disease…’ The statement would be more accurate with the addition of one word: dietary supplements are commonly taken to help prevent chronic disease. In other words, dietary supplements should not be expected, in and of themselves, and without the synergy of other healthy habits, to prevent chronic disease. This study, however, attempts to tease out one piece of the healthy equation for good health—dietary supplements. CRN maintains that nutrients may be robbed of their beneficial effects when viewed as if they were pharmaceutical agents, with scientists looking to isolate those effects, good or bad. It’s important to keep in mind that this is an associative—not a cause and effect—study. Further, the authors themselves have noted additional limitations. In fact, when the authors did their initial [minimum adjusted] analysis, it appears they actually found benefit for many of the supplements, not just calcium; yet instead of stopping there, they went on to “further adjust” the data, possibly until they found statistics worthy of this publication’s acceptance. The study may make for interesting scientific water cooler discussion, but certainly does not warrant sweeping, overstated concerns for elderly women. Further, the authors show their own bias with this statement: ‘We recommend that they [dietary supplements] be used with strong medically-based cause, such as symptomatic nutrient deficiency…’ which basically means these researchers would rather wait till we all get scurvy before acknowledging any need for supplemental nutrients. Our advice to consumers: your best chance for living a long and healthy life is to engage in healthy lifestyle practices, and many in the scientific community maintain that rational, reasonable use of vitamins and other supplements is part of that equation. Talk to your doctor, or other healthcare practitioner, if you have concerns—but read between the lines of individual studies and don’t make your decisions—either for or against supplements—based solely on hype.”
Statement by Steve Mister, president and CEO, Council for Responsible Nutrition: “Consumers continue to look for the best way to live long and healthy lives, and as much as we would like for science to easily give us answers, the fact is that science is not black and white. But even more concerning is the recent drive to combine political agendas with what should be pure science. The supplement industry regularly gets accused of this practice—in some cases rightly so—yet medical journals seem to be given a pass, as if somehow they held no bias whatsoever. Let’s look at some of the facts in this publication. First, within the article itself are a number of opinions including this one: ‘Also, cumulative effects of widespread use, together with food fortification, have raised concern regarding exceeding upper recommended levels…’ It’s quite popular these days to talk about overnutrification, but in fact research consistently shows that most people are falling short in several key nutrients such as potassium, calcium, vitamin D, and fiber while certain subpopulations fall short in folate, vitamin B12, and iron. Second, the authors advise that dietary supplements only be used ‘with strong medically-based cause, such as symptomatic nutrient deficiency…’ Given the high dosages of iron reportedly being used by the women in the study— iron is the supplement for which there was the strongest negative association—it is highly likely the participants were taking the high dosage of iron reported in the study under a physician’s care for an iron deficiency which may itself have resulted in a shortened lifespan. But the piece purports to warn against over-the-counter use of vitamins. Next, the publication invited a commentary from a scientist whose opinion on supplements and their potential role in good health is already well-known, and whose own work has been the subject of controversy in scientific circles. In the spirit of true scientific discourse, wouldn’t it have been more appropriate to invite a commentary from a researcher who might have looked at the data in its entirety, with sufficient lead time, and provided a different perspective? The commentary states: ‘…Therefore, we believe that politicians and regulatory authorities should wake up to their responsibility to allow only safe products on the market.’ Critics of dietary supplements will continue to advocate that vitamins and minerals should be regulated like drugs, but even they should realize that although drugs undergo rigorous RCT testing, many safety issues for drugs still do exist. Furthermore if nutrients were regulated like drugs, the cost and availability of supplements would make it difficult for average consumers to make these products part of their healthy lifestyle. The editors add their own ‘editorial note,’ using this study as an opportunity to bemoan the fact that ‘A better investment in health would be eating more fruits and vegetables, among other activities.’ This recommendation comes despite the fact that we don’t see a lot of RCTs for fruits or vegetables either. Even without RCTs, we agree that people should be eating more fruits and vegetables; however, in a practical world, consumers are not doing that, and dietary supplements are an option—not a substitute—for getting some (not all) of the health benefits from fruits and vegetables. It’s time scientific journals acknowledge they have some biases, just like industry.”

A government panel is saying PSA blood tests do more harm than good and healthy men should no longer receive the tests as part of routine cancer screening. The recommendation by the U.S. Preventive Services Task Force, goes against the assumption that finding cancer early is always a good thing. Not so, said Dr. Virginia Moyer of the Baylor College of Medicine, who heads the task force."We have put a huge amount of time, effort and energy into PSA screening and that time, effort and energy, that passion, should be going into finding a better test instead of using a test that doesn't work," Moyer told The Associated Press late Thursday. The task force analyzed all the previous research on this subject, including five major studies, to evaluate whether routine screening reduces deaths from prostate cancer. The conclusion: There's little if any mortality benefit. But there is harm from routine screening: impotence, incontinence, infections, even death that can come from the biopsies, surgery and radiation, Moyer said. Moyer said 30 percent of men who are treated for PSA-discovered prostate cancer suffer significant side effects, sometimes death, from the resulting treatment. About a third of men ages 40 to 60 have brewing prostate cancer but "the huge majority of them will never know it in their lifetime if they are not screened," she added.

Editor note: The critical period for maternal folate intake seems to be the first few weeks of fetal development. Ensuring adequate folate intake during this period is a vexing problem because the fact of pregnancy may not be known even to the mother at this early stage. The confluence of the problem of getting women of childbearing age to eat an adequate amount of folate with the observation that adequate folate helps prevent neural tube defects (NTDs) led to the addition of folic acid to grain foods in the US food supply starting in 1998. This strategy has been effective in getting folate to young potential mothers and also in reducing NTDs.
Bonnie - this is why it should be essential that young women in child-bearing years take a multivitamin with at minimum 400 mcg. of folate. As the researchers above allude to, food fortification helps, but is not enough.
Bonnie - as expected, all of the fears that detractors of GMOs had from the beginning are coming to fruition.

Journal Nutrition, October 2011
Foods, Fortificants, and Supplements: Where Do Americans Get Their Nutrients?
"Limited data are available on the source of usual nutrient intakes in the United States. This analysis aimed to assess contributions of micronutrients to usual intakes derived from all sources (naturally occurring, fortified and enriched, and dietary supplements) and to compare usual intakes to the Dietary Reference Intake for U.S. residents aged ≥2 y according to NHANES 2003–2006 (n = 16,110). We used the National Cancer Institute method to assess usual intakes of 19 micronutrients by source. Only a small percentage of the population had total usual intakes (from dietary intakes and supplements) below the estimated average requirement (EAR) for the following: vitamin B-6 (8%), folate (8%), zinc (8%), thiamin, riboflavin, niacin, vitamin B-12, phosphorus, iron, copper, and selenium (<6% for all). However, more of the population had total usual intakes below the EAR for vitamins A, C, D, and E (34, 25, 70, and 60%, respectively), calcium (38%), and magnesium (45%). Only 3 and 35% had total usual intakes of potassium and vitamin K, respectively, greater than the adequate intake. Enrichment and/or fortification largely contributed to intakes of vitamins A, C, and D, thiamin, iron, and folate. Dietary supplements further reduced the percentage of the population consuming less than the EAR for all nutrients. The percentage of the population with total intakes greater than the tolerable upper intake level (UL) was very low for most nutrients, whereas 10.3 and 8.4% of the population had intakes greater than the UL for niacin and zinc, respectively. Without enrichment and/or fortification and supplementation, many Americans did not achieve the recommended micronutrient intake levels set forth in the Dietary Reference Intake."

- 30 minutes to 1 hour before exercise, drink or supplement with:
Tart Cherry Gel or 8 oz. 100% Tart Cherry Concentrate
Cranberry Extract or 8 oz. 100% Cranberry Concentrate
These help reduce the amount of lactic acid that builds up in the muscle tissue.
- After exercise and stretching, apply arnica gel topically.

-Check for anemia (especially women; endurance activities use huge amounts of iron)
-Hydrate properly (not too much or too little)
-Take magnesium. It is the most vital nutrient because it protects the heart. You should take at least 350 mg. for training and the race itself.
Bonnie - most of this movie is "right on", except the part about plant food proteins being more bioavailable than animal proteins. There is no research to prove this assumption. In fact, humans are omnivores (with the ability to digest both plant and animal foods). Genetically some individuals, especially blood type O's, have powerful enzymes and a large amount of bile to break down animal proteins efficiently, but cannot break down plant proteins. Spirulina is both plant and animal, so efficiently absorbed, but you would have to drink s gallon of spirulina liquid to get the protein availability of 4 ounces of chicken breast!
This movie promotes a primarily raw foods vegan diet. Yes, raw food is beneficial. If you can't get at least half of your diet from raw foods, you can compensate by taking digestive enzymes. My sickest clients are vegans because they can't possibly get enough protein to repair cell damage. But I think the movie has tremendous value in that it helps the public think about what they're putting into their bodies and that real food is the best medicine!
