What it is

BHA, or Butylated Hydroxyanisole, is a synthetic antioxidant. It is made by chemically combining 4-methoxyphenol and isobutylene. It is a waxy solid.

Why it's used

Manufacturers add BHA to foods to prevent fats and oils from going bad (oxidizing or becoming rancid). It helps extend the shelf life of products like baked goods, snack foods, cereals, and some meat products.

Health notes

BHA is approved by the FDA as a direct food additive. JECFA has evaluated BHA and set an acceptable daily intake. The International Agency for Research on Cancer (IARC) classifies BHA as "possibly carcinogenic to humans" (Group 2B), based on studies in animals. However, human studies have not shown a clear link to cancer, and the evidence is mixed regarding its effects at typical intake levels.

Allergen info

Not a major allergen.
