Women who eat large amounts of carbohydrates with a high glycemic load may be at much higher risk for developing colon cancer, according to a study that appeared in the February 2004 issue of the Journal of the National Cancer Institute. The culprit? Higher blood sugar levels and an elevated insulin response that can foster tumor growth. In fact, women who frequently ate foods like refined grains (breads, cookies, cakes, etc. made from white flour) were nearly three times more likely to be diagnosed with colon cancer than women who ate these foods less often.
The bottom line: Cut back on sweets, refined-grain products and potatoes, and replace these items with whole grains, fruits and vegetables.
