It is the job of the immune system to recognize, attack, and destroy foreign invaders, one of which is a cancerous cell. Therefore, anything that strengthens the immune system helps to ward off cancer. Vitamin A is essential in stimulation of the immune system. Plant products are the best source of beta-carotene and other relatives called carotenoids. These are the best forms of vitamin A for the body and its immune system. These compounds serve as antioxidants, which help the body dispose of chemicals called free radicals. Free radicals can genetically damage normal cells and set the stage for cancer. Vitamin A also helps body tissue to develop in a normal, orderly way. It is this lack of normal, orderly development that is common in cancerous cells. Vitamins C and E also play vital roles in antioxidant and free radical scavenger activity.
Whole foods provide more anticancer protection than does just taking vitamins. Another advantage to whole foods is the phytochemicals found in them. There are thousands of phytochemicals that seem to have a role in fighting cancer. An increased fiber intake clearly reduces the risk of developing colon cancer, and there is virtually no fiber in meat and animal products. Selenium, a trace mineral found in whole grains, has also been shown to decrease some forms of cancer.
Increased body weight, increased meal frequency, and eating between meals have been linked to an increase of several types of cancer, including colon cancer.
Regular exercise has many benefits, including increasing interleukin-1, plasma interferon levels, natural killer cells, and blood lymphocytes. Each of these is important in the fight against cancer. Although excess sunlight is harmful, sunlight in moderation may be helpful in preventing some forms of cancer. Adequate control of stress is also vital for a healthy immune system and the ability to fight cancerous cells.
By adapting a personal cancer preventative and protective lifestyle, we can greatly reduce our risk of cancer. Surely you want to have this protection against cancer and to share this information with the general public. Most cancers can be prevented!
