Insulin is a highly anabolic hormone that speeds the rate at which amino acids enter the cells and increases protein synthesis. High insulin levels
create an environment conducive to colon tumors. Diets with a high glycemic index - high in simple sugars - trigger increased levels of insulin.
Researchers from Harvard showed that men, but not women, who eat high glycemic index diets, have an increased risk of colon cancer. Examples of high
glycemic index foods include baked potatoes, table sugar and jam, while lower glycemic index foods include brown rice and cooked corn. The study
examined more than 40,000 women and 51,000 men and followed them for eight to 10 years.
Eating a high glycemic index diet increased the risk of colon cancer three to six times above those who ate diets containing more complex carbohydrates. Nutritionists recommend that people avoid high glycemic index foods because they can cause large changes in blood sugar and promote obesity, heart disease and cancer. Eating high glycemic index foods causes problems in the cells and organs, such as insulin resistance, high blood insulin levels, and poor blood flow regulation. These lead to sexual problems, heart disease, obesity, high blood pressure and high cholesterol. Prevent these problems by exercising regularly and choosing low saturated fat, high-fiber, low glycemic index foods that take longer to digest.
