How To Prevent Cancer?
The best defense against cancer is a good offense. Some researchers believe we could cut our cancer risk dramatically by changing the way we eat. People need to eat five to nine servings of fruits and vegetables a day.Researchers are investigating the cancer-fighting potential of more than 1000 nutrients. These include natural age to our cells by free radicals, oxygen molecules formed by normal metabolic processes as well as by chemicals. These substances act like biological terrorists in the body, damaging or killing healthy cells, including aging, impaired immunity, cataracts, and cancer. Antioxidants, primarily vitamins C and E, beta carotene and the mineral selenium destroy free radicals and protect against cellular damage.Cruciferous vegetables, such as broccoli, cauli-flower, cabbage, and Brussels sprouts, are excellent sources of antioxidants

Other nutrients also protect us against cancer. For instance, both calcium and vitamin D (which is formed in our skin in reaction with sunlight) ward off colon cancer. Calcium may bind with, or attach itself to, cancer-causing substances in the digestive vitamin D boosts calcium’s effectiveness. Fiber too, may protect us – but its role is controversial. Certain types of fiver, particularly the insoluble form found in wheat bran and many vegetables, seem most moving foods faster through the digestive system, by diluting or inactivating carcinogens in some ways, or by reducing intestinal acids and bacterial enzymes, which may promote cancer growth.
The body, particularly the liver and intestines, naturally produces cholesterol. The foods we eat also affect the amount of cholesterol in our blood. Although cholesterol has received much negative attention as a factor in heart disease, a certain amount of cholesterol is in fact essential for good health. Cholesterol is involved in the production of many hormones, including the sex hormones; the formation of the outer membranes protecting our body cells; and liver function.
When Cholesterol levels become too high, as indicated by measurements of the amount to cholesterol in the blood, the excess cholesterol build up within the arteries (a condition called atherosclerosis), adding to the risk of heart disease. The number-one way to reduce blood cholesterol is by cutting back on fats. Foods high in fat, especially saturated fat, raise blood cholesterol levels more than any other foods, even those high in cholesterol. Limit the number of eggs you eat per week to four; egg whites are cholesterol-free, but a single egg yolk has 213 mg of cholesterol.
