A diet rich in foods that trigger a quick and drastic jump in blood sugar levels can do more than just boost risk of type 2 diabetes and contribute to obesity. A new study indicates they may also lead to colon cancer.
Researchers at Harvard and UCLA find that the future risk of colorectal cancers is nearly three times higher in women who eat the most high glycemic-load foods compared with those who eat lesser amounts. These foods include breads, pastas, pancakes, and other carbohydrates made from refined "white" grains, as well as other processed or sugary foods such as cakes, cookies, and other snacks.
