BHA & BHT
What is BHA & BHT?
BHA (Butylated Hydroxyanisole) and BHT (Butylated Hydroxytoluene) are synthetic antioxidants used as preservatives to prevent oils and fats in foods from oxidizing and becoming rancid. They are produced by a chemical process that combines various compounds to create these stable preservatives.
These additives are used to extend shelf life in foods like cereals, snack foods, and pizza. Despite their effectiveness, BHA and BHT are controversial due to research suggesting potential carcinogenic effects on laboratory animals. However, the evidence is mixed, and regulatory agencies have deemed them safe at low concentrations.
When you see BHA or BHT on a label, it's usually to maintain product quality and prevent spoilage. Their inclusion often reflects a product's processing level rather than inherent safety issues.
