Some studies have indicated that drinking low reduces the incidence of cancer, however others studies have thrown doubt upon these results.
SUPPLEMENTS OF VITAMINS AND OTHER SUBSTANCES
Her are listed the foremost important cancer preventing effects advised by results from recent projects. However, analysis goes on, and these results are not nonetheless complete or completely certain.
These substances offer general cancer prevention effects: Sulforaphanes found in broccoli and alternative cruciferous vegetables.
Colo-rectal cancer: These substances help protect against colo-rectal cancer: Vitamin B-6 (pyridoxine), Folic acid / folate in combination with alternative B-vitamins, Selenium, Indol-3-carbinol from cruciferous vegetables, Genistein from soy, and presumably additionally vitamin D. Alfa-tocoferol (a quite Vitamin E) may help, but project results are not conclusive jet.
Gastric cancer: Substances which will facilitate stop gastric cancer, and even facilitate cure changes that can evolve into gastric cancer are: Vitamin C, Beta-carotene, (a precursor of vitamin A), Alfa-tocoferol (a kind of Vitamin E), Indol-three-carbinol from cruciferous vegetables, Genistein from soy.
Breast Cancer: The incidence of breast cancer will be lowered by: Folic acid / folate, Vitamin B-6 (pyridoxine), Selenium, and presumably vitamin D.
Prostate Cancer: These substances could help shield against Prostate cancer: Selenium and Alfa-tocoferol (a quite Vitamin E). An extended study is under approach, but the results from the study aren’t conclusive yet.
Bladder cancer: The possibility of obtaining bladder cancer is possibly lowered by alfa-tocoferol (a kind of Vitamin E).
Lung cancer: Substances that provides protection against Lung Cancer are: Isoflavones from soy. Indol-3-carbinol from broccoli and alternative crusiferous vegetables, Genistein from soy and possibly Vitamin D.
Results from analysis comes counsel that supplements added to the diet to prevent cancer should contain many working substances derived from natural sources, which it is not wise to use heavy doses of simply one substance.
NUTRIENTS THAT MAY HAVE THE OPPOSITE EFFECT
Beta-carotene and vitamin A supplements might increase the prospect for heavy smokers of getting lung cancer and other cancers caused by smoking, according to results from epidemiologic studies.
But, these vitamins within the food doe not increase this risk. It is not clear what effect beta-carotene have on lung cancer in combination with alternative supplements or by non-smokers. The results from these studies are controversial.
