Vitamins as a Shield Anticancer

Unlike carbohydrates, fats and proteins, vitamins are not an energy source, but serve as chemical models for enzymes related to metabolic function, cell production, tissue repair and other vital processes.

Vitamin C, and precursor of vitamin A as beta-carotene, are antioxidants, so they are considered as protectors of the oxidation of cells, and thus of degenerative diseases such as cancer.

Vitamin C or ascorbic acid has been widely documented. Today is known as stress vitamin because of its association with all processes related to metabolic stress. As an antioxidant shield your needs are greater than the rest of the vitamins, which in just a few milligrams fulfill these functions.Vitamin C is found in vegetables like broccoli, cucumber, cabbage, tomato and pepper. The latter two should be eaten raw and red well. Is found in fruits, citrus, papaya, melon and guava.

In the prevention of cancer are linked vitamin C and E with the addition that the latter is within the fat-soluble. Therefore, all foods containing fats or oils are good vehicles for this vitamin. It is only synthesized by plants, which constitute its primary source.

Vitamin E is found in foods such as wheat germ, corn, nuts, grains, oilseeds, olives, and spinach and other green leafy vegetables and vegetable oils such as corn, olive, sunflower and soy, mainly. The latter is one of the most amounts of vitamin E per gram contributors.

In the case of vitamin A, many stories have been woven around its importance in the diet and the prevention of many diseases, including cancer.

Vitamin A or Retinol is a vitamin of animal origin. Made in the human body from pro-vitamin A or beta-carotene (plant form of the vitamin). Beta-carotene is converted into retinol in the human body when required. We eat beta-carotene in vegetables or vitamin A, and formed in food of animal origin.
