ADA posts cancer prevention tips

Here's a list of 10 diet and activity recommendations highlighted this week in Chicago at the annual meeting of the American Dietetic Association (ADA).

• Be as lean as possible without becoming underweight.
• Be physically active for at least 30 minutes every day.
• Avoid sugary drinks, and limit consumption of high-calorie foods, especially those low in fiber and rich in fat or added sugar.
• Eat more of a variety of vegetables, fruits, whole grains, and legumes (such as beans).
• Limit consumption of red meats (including beef, pork, and lamb) and avoid processed meats.
• If you drink alcohol, limit your daily intake to two drinks for men and one drink for women.
• Limit consumption of salty foods and food processed with salt (sodium).
• Don't use supplements to try to protect against cancer.
• It's best for mothers to exclusively breastfeed their babies for up to six months and then add other liquids and foods.
• After treatment, cancer survivors should follow the recommendations for cancer prevention.

Why These Cancer Recommendations?

Walter Willett, MD, DrPH, an epidemiology professor who leads the nutrition department the Harvard School of Public Health, was on the international team of scientists that wrote the recommendations.

At the ADA meeting, Willett said the first recommendation -- to be as lean as possible within the healthy weight range -- is "the most important, by far."

But there is one recommendation that Willett says may be a "mistake" -- the one about not taking supplements. Vitamin D supplements may lower risk of colorectal cancer and perhaps other cancers, notes Willett. He predicts that that recommendation will be a top priority for review.

Bonnie - the ADA has always been against supplements, to their detriment. The fact that Willett, who was on the panel, points this out publicly shows the divisiveness within the organization.
