Everyone knows that not smoking, not drinking alcohol, and maintaining a healthy weight are the keys to avoiding cancer. But what else can you do if you also want to go further to prevent cancer? Quite simply, eat healthy. Although factors such as genetics and environment cannot be avoided in some cases and play an important role in the development of cancer, good eating habits can reduce the probability of cancer. Studies have shown that dietary patterns are strongly associated with the risk of several cancers, and that a low-fat diet, a high-fiber diet, and a diet rich in fresh fruits, vegetables and mixed grains are associated with a reduced risk of developing many cancers. There are several main points to note: Do not eat too much red meat each day. Limit high-fat foods. Avoid salty snacks. Avoid smoking and drinking alcohol. Do not eat burnt foods. Avoid being overweight. Walk briskly for one hour a day (or do equivalent exercise). Eat different types of fresh fruits and vegetables every day. Plant-based foods are rich in fiber, antioxidants and anti-cancer substances that are effective in preventing the development of cancer. A good diet can even help those with a family history of certain cancers out of the woods. Improved dietary habits are associated with cancer prevention, but once cancer has occurred, there is no evidence to suggest which dietary treatments can cure cancer. However, proper dietary modification can effectively improve a range of symptoms of physical discomfort and malnutrition due to cancer.
