Aflatoxins if not properly stored over time, formed in stale tea and different herbs, and when added to their water appears white film as an indication that the sheet is long dead and turned into hay.Aflatoxins have strong carcinogenic.They act on almost all cell components.All violations of aflatoxins lead to "cha
Currently aflatoxins family includes four main representative - aflatoxins B1, B2, G1, G2, and more than 10 compounds that are metabolites or derivatives of the main group - M1, M2, B2a, G2a, GM1, P1, Q1, and others.Producers of aflatoxins are some strains of two species of microscopic fungi: Aspergillus flavus and Aspergillus parasiticus.
Although aflatoxins cause cancer in animals, some drugs reduce their content in nuts, seeds and legumes in which aflatoxins are considered "inevitable impurities".
not practical and not possible at home to try to remove foodstuff from aflatoxin, so as to make them more secure.Especially since aflatoxin in small amounts over a lifetime does not pose much of a threat.Safe

- Cause hepatic necrosis, leading later to cirrhosis and / or liver carcinoma;
- Violate the metabolism of vitamin D, thereby decreasing bone strength;
- Snizhzhayut formation of bile salts:
- affects the absorption of fats and pigments;

- buy nuts and peanut butter only in the most well-known and tested for high quality products trading networks;
- to throw out anything that looks like mold, all discolored or shriveled.
- toxins are very stable and retain activity even after thermal treatment at high temperatures, so spoiled nuts and dried fruits should not be washed, fry, boil - to neutralize the poison in this way is impossible.
In recent medical studies have established that regular presence in the diet of umbrella vegetables such as carrots, parsnips, celery and parsley, reduces the carcinogenic effects of aflatoxin.
