E321 Butylated hydroxytoluene

What is E321 or Butylated hydroxytoluene?

Butylated hydroxytoluene (BHT), or E321, is a synthetic antioxidant used to prevent oxidation in fats and oils, which helps extend the shelf life of processed foods. It is found in packaged snacks, cereals, and other processed goods to maintain their quality.

Why do I have an intolerance?

Intolerance to BHT can occur when the body cannot effectively process this synthetic additive. Some individuals may experience reactions such as nausea, headaches, or allergic symptoms when exposed to BHT. Over time, sensitivity can develop with regular consumption of foods containing E321.

What can I do about it?

Avoiding foods that contain BHT is the best way to manage an intolerance. Check food labels for E321 and choose fresh, whole foods without preservatives. Preparing homemade snacks and meals from scratch can significantly reduce your exposure to BHT and other synthetic additives.
