If you really want to lower your cancer risk you have to get your weight under control. This is because being significantly overweight is a major risk factor for cancer, especially of the breast. To put this into context, being obese puts you at almost as great a risk of cancer as smoking.

Low GL for Cancer Prevention

Study 1

According to Dr Walter Willetts of the Harvard School of Public Health, being obese accounts for 14 per cent of cancer deaths in men and 20 per cent in women, compared with about 30 per cent each for smoking. However, one of the most significant new risk factors for breast cancer are indicators of blood sugar problems.

Study 2

Eating foods with a high glycemic index (GI) and/or glycemic load (GL) have been linked to a higher risk of many cancers, including breast, colorectal, pancreatic, ovarian, thyroid, endometrial (womb), and gastric cancer. Conversely, low-GI and/or low-GL diets are associated with a reduced risk of breast, colorectal, ovarian and endometrial (womb) cancers. For example, researchers in Italy in 2005 found that regularly eating sweet foods, including biscuits, brioches, cakes, ice cream, honey and chocolate, increased the risk of breast cancer. As the authors point out, these foods also contain other nutrients that are potentially involved in causing breast cancer, including saturated fats.
