A diet high in fruits, vegetables, and whole grains, that is low in processed foods, red and processed meats, and refined grains, is associated with a decreased risk of cancer.
Nutritious diet that includes a variety of fruits, vegetables, and whole grains includes key vitamins and minerals, as well as fiber and other important nutrients that can boost your body's defense against cancer. Eating a diet high in red and processed meats, as well as refined grains, on the other hand, may increase inflammation and free radicals, which may increase risk of certain types of cancer.
The scientific evidence for a correlation between diet and cancer prevention is supported by numerous studies. For example, a 2007 prospective study of over 50,000 people found that individuals with diets rich in fruits, vegetables and whole grains were 20% less likely to develop cancer than those who ate less of those foods. Other epidemiological evidence, as well as laboratory and animal studies, suggests that certain nutrients found in these foods (including natural antioxidants and phytochemicals) may play a role in decreasing cancer risk.
