Food May Be Important in Cancer Prevention?

In General What Substances in Food May Be Important in
Cancer Prevention ?
As mentioned several times, people who eat more fruits, vegetables, leg-
umes, and whole grains are at a lower risk for various cancers. It now
appears that many other factors in these foods, beyond the established
nutrients, impact the development of cancer. These substances include
phenols, indole, aromatic isothiocyanates, carotenoids, fibers, terpenes,
polyphenolic, and organosulphur compounds. Many of these substances
have been studied in cell cultures and also in animals and appear to be
very promising. Together with vitamin and mineral antioxidants such
as vitamins E and C and copper, selenium, zinc, and manganese these
products may account for much of the cancer risk-reducing effects associ-
ated with diets high in fruits, vegetables, legumes, and whole grains.
  So, the best things to do nutritionally are:
•   eat five or more servings of fruits and vegetables a day
•   eat more whole grain products
•   choose foods lower in fat and saturated fat
•   maintain a body weight closer to your ideal body weight
•   engage in regular exercise (especially aerobic) to assist in maintaining
    a lower body weight and reducing stress
•   limit consumption of fatty red meat
•   do not use alcohol excessively
