BHA & BHT

BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene) are synthetic chemical compounds. They are created in laboratories and are not found naturally in foods.

These compounds are used as antioxidants to prevent fats and oils in food from spoiling and going rancid. They help extend the shelf life of products like cereals, snack foods, baked goods, and some meat products.

BHA and BHT are permitted by the FDA as direct food additives. Both BHA and BHT have been evaluated by JECFA, and acceptable daily intakes have been set. The International Agency for Research on Cancer (IARC) classifies BHA as "possibly carcinogenic to humans" (Group 2B). While some studies have raised questions about potential health effects, regulatory bodies like JECFA and EFSA consider them safe at typical intake levels.
