Nutrition and cancer prevention
Nutrition and cancer prevention (Salem Health: Cancer)
Epidemiology: As a rule, the human immune system is able to stop carcinogens from damaging cells within the body. However, sometimes cell deoxyribonucleic acid (DNA) is attacked and altered, causing cancer cells to begin to develop and multiply. Studies show that most cancers can be prevented through lifestyle choices (a healthful diet, avoidance of tobacco and excessive alcohol use, and adequate physical activity) and changes in the environment. Strong associations link diet to some cancers, but many other factors contribute as well. Genetics, infectious agents, some viruses, and exposure to radiation, chemicals, and some carcinogenic substances in the air, water, and soil also play a role. The American Cancer Society reported that 23.1 percent of deaths in the United States in 2004 were due to cancer.
Nutrition risk factors: Studies find populations that eat a diet rich in fatty foods, especially animal fats, have higher rates of cancer than populations that eat a plant-based diet high in whole grains, vegetables, fruits, and legumes. Increased death rates from breast, prostate, and colon cancers are associated with high-fat diets. Higher rates of cancer have also been linked with the consumption of low-fiber diets and excessive alcohol.
Being overweight or obese is also strongly linked with cancer. Overweight people are more likely to develop breast (postmenopausal women), colon, endometrial,...
