What it is
Butylated hydroxyanisole (BHA) is a synthetic antioxidant. It is made from chemicals derived from petroleum. BHA is used to prevent fats and oils in foods from becoming rancid.
Why it's used
Manufacturers add BHA to foods containing fats and oils to extend shelf life by preventing oxidation. It is commonly found in vegetable oils, baked goods like cookies and biscuits, and snack foods.
Health notes
In the U.S., BHA is generally recognized as safe (GRAS) by the FDA when used as a food additive. Some studies in animals have raised concerns about BHA's potential health effects at very high doses, but regulatory bodies like the WHO/IARC have not classified it as carcinogenic to humans. Evidence regarding its effects in humans at typical dietary intake levels is mixed and requires further research.
