New research reported in the Archives of Internal Medicine suggests that pre-menopausal women who consume a large amount of red meat may increase their risks of breast cancer. This study differs from other previous research in that it includes younger women (aged 26 to 46) and it controls for the presence of hormonal receptors that are known to increase the risk of cancer. The data is from the Nurses’ Health Study.

Researchers in New Zealand report a re-analysis of several studies and find that almost any form of exercise is helpful in glucose control and type 2 diabetes risk reduction. The article in the Diabetes Care Journal (November 2006) looked at 27 previous studies’ data. The authors suggest that exercise combined with diet and medical intervention might have stronger effects, but these multiple factors are not tested in this research.

Results published this past week in the New England J. of Medicine conclude that it’s the type of carbohydrates and fats consumed, not just the quantities, that are associated with heart disease.
Using data from the Nurses’ Health Study, the researchers looked at the relationships between diet and heart disease for over 82,000 women. They found that the percentage of calories from carbs, fats and protein were not related to heart disease. But, the important thing they found is that women whose dietary sources included ‘good’ fats like olive oil, proteins from beans or soya products, and whole grain carbohydrates rather than refined sugars had 30% less chance of developing heart disease. They specifically singled out the glycemic load as a leading indicator: consuming refined carbs like sugars in soft drinks increased the glycemic load and was correlated with the development of heart disease.

Cold and flu season is upon us but the good news is that research published in November’s issue of the American Journal of Medicine suggests that regular moderate exercise can prevent common colds. Cornelia M. Ulrich, an associate member of the Fred Hutchinson Cancer Research Center in Seattle, and her colleagues found that older women who took a half-hour walk each day for a year reported half the number of colds as women of similar age who didn’t exercise. “I think it is another set of data that now adds to the growing awareness that one of the most powerful ways of keeping your sick days down is to do nearly daily [physical] activity,” says David Nieman, a veteran researcher of the exercise/colds connection.

A new study in Reuters Health finds that women who dine in restaurants or get take-out food consume up to 300 extra calories and 10 to 16 extra grams of fat. “Restaurants may present a high-risk environment for bingers and dieters, contributing to loss of control and excess consumption,” writes study author Dr. Gayle M. Timmerman, an associate professor at the University of Texas at Austin School of Nursing. Click here for the full article.
