Starch Rich Foods Risks For Breast And Ovarian Cancers

Animal products are associated with lowered risks of breast and ovarian cancers. Eat diets richer in vitamins, fiber, unsaturated fats, and animal fats.

We identified 4 major dietary patterns named Animal products, Vitamins and fiber, Unsaturated fats and Starch-rich. The animal products pattern and the unsaturated fats pattern were inversely associated with breast cancer (OR = 0.74, 95% CI: 0.61-0.91 and OR = 0.83, 95% CI: 0.68-1.00, respectively, for the highest consumption quartile), whereas the starch-rich pattern was directly associated with it (OR = 1.34, 95% CI: 1.10-1.65). The vitamins and fiber pattern was inversely associated with ovarian cancer (OR = 0.77, 95% CI: 0.61-0.98), whereas the starch-rich pattern was directly associated with it (OR = 1.85, 95% CI: 1.37-2.48). In conclusion, the starch-rich pattern is potentially an unfavorable indicator of risk for both breast and ovarian cancers, while the animal products and the vitamins and fiber patterns may be associated with a reduced risk of breast and ovarian cancers, respectively.

Yes kids, glucose can do more damage to your body than protein. That could be the result of higher blood levels of insulin and insulin-like growth factor. My guess is that a lower glycemic index diet might not increase cancer risks as much as a higher glycemic index diet with the same amount of carbohydrates.

Previous studies have produced different results. We can't be certain this latest study is correct.

High alcohol intake has been consistently linked to breast cancer risk, but when it comes to other facets of the diet, studies have yielded conflicting results, according to the researchers on the current work, led by Dr. Valeria Edefonti of the University of Milan.

Another study just out in the American Journal of Epidemiology finds that men who eat a high fat diet are at greater risk of benign prostate hyperplasia (BPH).

The researchers found that a high-fat diet increased the risk of benign enlargement of the prostate by 31 percent, and that daily consumption of red meat increased the risk by 38 percent.

The study also found that eating four or more servings of vegetables daily was associated with a 32-percent reduction in risk, consuming high amounts of lean protein (about 20 percent of daily calorie intake) was associated with a 15-percent risk reduction, and that regular, moderate alcohol consumption (no more than two drinks a day) was associated with a 38-percent decline in BPH risk.

Note that for women that alcohol consumption will probably up your breast cancer risk. Also, other studies find increased risk of colon cancer from eating processed meats. So avoid the hot dogs and salami.

Proteins from lean sources are best for men.

Red meat increased the likelihood of BPH, but only in men who ate it every day. Men who ate the most fat were 31% more likely to develop BPH, while the highest consumers of protein actually cut their risk by 15%.

The protein finding "doesn't mean go out and eat lean meat, it means go out and find lean sources of protein, which can be quite diverse," Kristal told Reuters Health, pointing to beans and vegetable proteins as two possibilities.

I wonder whether the BPH risk comes from all sources of fats or just particular kinds of fats.

While the net effects of some types of foods might seem controversial note that the benefits of vegetables consumption seem pretty clear. Vegetables will cut the risks of many types of cancer as well as other diseases of old age.
