What it is

Butylated hydroxytoluene (BHT) is a synthetic compound. It is made through a chemical process involving p-cresol and isobutylene. BHT is a type of antioxidant.

Why it's used

Manufacturers add BHT to foods to prevent fats and oils from becoming rancid, which helps extend shelf life. It is commonly found in foods containing fats, such as baked goods, cereals, potato chips, and shortenings.

Health notes

In the U.S., BHT is generally recognized as safe (GRAS) by the FDA for use as a food additive. Regulatory bodies like JECFA and EFSA have evaluated BHT. Some studies have raised questions about its potential effects, but evidence from typical dietary intake is mixed and not conclusive. More research is ongoing.

Allergen info

BHT is not derived from any of the 9 FDA major allergens and does not contain gluten.
