BHA (E320)
BHA (E320) is an antioxidant that Digestoa flags as high risk. Common concerns include possible carcinogen (iarc 2b).
What is BHA?
BHA (butylated hydroxyanisole) is a synthetic antioxidant that stops fats going rancid. IARC classes it as a possible human carcinogen.
Is BHA bad for you?
Digestoa flags BHA as high risk. Regulators permit it, but safety reviews and studies have raised concerns including possible carcinogen (iarc 2b), endocrine concerns. How often you eat it matters more than a single exposure.
- Possible carcinogen (IARC 2B)
- Endocrine concerns
What foods contain BHA?
Crisps, instant mashed potato, chewing gum, butter, lard and many packaged fatty foods..
Digestoa's take
You don't need to panic over a single product that contains BHA. But it's a useful flag: when you see E320 on a label it often signals a more processed product, and there's usually a cleaner alternative.
Safer swaps
Look for products preserved with vitamin E (E306), or fresher items with shorter shelf lives.
