What is BHA?

Butylated hydroxyanisole (BHA) is a phenolic compound (antioxidant) that is often added to foods to preserve fats. [1]

Is BHA Safe?

BHA has undergone the additive application and review process required by the US Food and Drug Administration. However, the same chemical properties which make BHA an excellent preservative may also be implicated in health effects. The oxidative characteristics and/or metabolites of BHA may contribute to carcinogenicity or tumorigenicity; however the same reactions may combat oxidative stress.

There is evidence that certain persons may have difficulty metabolizing BHA, resulting in health and behavior changes. BHA may also have antiviral and antimicrobial activities. [1]

Is BHA Artificial or Natural?

Specifically, BHA, short for Butylated Hydroxyanisole, and BHT, Butylated Hydroxytoluene, are both artificial preservatives added to oils to slow down deterioration. [2]
