Cancer researchers in the United Kingdom have concluded that drinking as little as one glass of alcohol a day increases your risk of developing bowel cancer by about 10 percent. And, the more you drink, the more your risk of cancer increases.
The study included almost 480,000 people in the U.K. who were questioned
about their level of alcohol intake, with follow-ups over the course of six years. In that period, 1,833 developed colon cancer.
The study showed that those who drank more than 30 grams of alcohol per day (less than two pints of strong lager) raised their cancer risk by about 25 percent.
According to Dr. Walker, Cancer Research UK’s director of cancer information, “While there is increasing evidence that over indulging in alcohol can increase the risk of some cancers, research also shows that by far the biggest risk for life threatening diseases is the combination of smoking together with drinking alcohol.”

Eating Blueberries Slashes Your Colon Cancer Risk
Adding blueberries to your diet may be a natural way to prevent
colon cancer, according to researchers at Rutgers University, and the U.S. Department of Agriculture.

In a study of 18 rats with colon cancer, those fed a diet supplemented with the blueberry compound pterostilbene had 57 percent fewer pre-cancerous lesions after eight weeks compared to the control group. Pterostilbene also inhibited genes involved in inflammation, which is thought to be a risk factor for colon cancer.

A past study has also found that blueberries are beneficial; when blueberry skins were fed to animals, their cholesterol was lowered. It’s thought that pterostilbene may prevent colon cancer by lowering lipids in your body.

Blueberries are rich in antioxidants called anthocyanins, and are a good source of ellagic acid, which is known to block metabolic pathways that may lead to cancer. There are 30 different blueberry species native to North America.
