Why does food go bad?

The Benefits: Food goes bad (rancid) because polyunsaturated fats, which are present in both plants and animals, react with oxygen over a fairly short period of time to create free radicals. Free radicals are definitely carcinogenic. BHT works by inhibiting this process by reacting with these radicals to form a MUCH more stable radical.

Are BHA and BHT Safe?

However, the same chemical properties which make BHA and BHT excellent preservatives may also be implicated in health effects. The research leads to conflicting conclusions. The oxidative characteristics and/or metabolites of BHA and BHT may contribute to carcinogenicity or tumorigenicity; however, the same reactions may combat oxidative stress and help detoxify carcinogens. Some studies indicate low doses of BHA are toxic to cells, while higher doses may be protective, while other studies yield exactly the opposite results.
