The facts: Butylated Hydroxyanisole is banned in 1 country/region (including Japan (banned for use in foods containing fats and oils)), though the FDA still allows it in the US. We can't tell you whether it's safe for your pregnancy — that's a conversation for your OB-GYN or midwife. What we can do is show you the regulatory facts and flag Butylated Hydroxyanisole on any product's label so you can decide with your provider. Commonly found in: Some Post and Kellogg's cereals (certain US formulations), Chewing gum, Potato chips.
TL;DR: Butylated Hydroxyanisole is banned in the EU and allowed in the US. Here's what to know if you're pregnant.

Butylated hydroxyanisole (BHA) is a synthetic phenolic antioxidant preservative derived from petroleum. It is a mixture of two isomeric compounds (2-BHA and 3-BHA). BHA prevents fats and oils from oxidizing (going rancid), extending shelf life. Its chemical formula is C11H16O2.
BHA is used at very low concentrations (typically 0.02% of fat content) to prevent oxidative rancidity in fats, oils, and fat-containing foods, extending shelf life. It is cost-effective, stable under heat, and used in snack foods, cereals, chewing gum, packaging materials, and cosmetics.
BHA is classified by the International Agency for Research on Cancer (IARC) as Group 2B (possible human carcinogen) based on studies showing it causes papillomas and squamous cell carcinomas of the forestomach in rats, hamsters, and mice at high doses. A 1983 NTP bioassay confirmed these findings. The National Toxicology Program lists BHA as 'reasonably anticipated to be a human carcinogen' in its Report on Carcinogens. The forestomach is an anatomical structure found in rodents but not humans, creating some uncertainty about direct extrapolation. EFSA's 2012 re-evaluation (EFSA Journal 2012;10(10):2588) concluded that BHA may have endocrine-disrupting potential based on animal data showing interactions with estrogen receptors and androgenic hormone pathways. EFSA found the ADI of 1 mg/kg body weight but noted concerns about endocrine effects. Japan banned BHA for use in foods containing fats and oils, consistent with its generally precautionary approach to synthetic food preservatives. In cosmetics, the EU Scientific Committee on Consumer Safety (SCCS) has assessed BHA and found potential endocrine-disrupting effects at dermal exposure levels. EWG rates BHA as high-concern in Skin Deep cosmetics database. The antioxidant paradox applies: while BHA prevents lipid oxidation in foods, it may paradoxically act as a pro-oxidant in certain biological contexts at certain doses.

Yes. Butylated Hydroxyanisole is banned in Japan (banned for use in foods containing fats and oils); restricted in European Union (restricted; banned in baby food), United Kingdom, Australia/New Zealand (ADI-based limits). The FDA still allows it in the US.
That's a decision for you and your OB-GYN or midwife — we don't give medical advice. What we can tell you is the regulatory status above. Many people choose to limit additives during pregnancy out of caution; bring this page and its sources to your next appointment.

Mixed tocopherols (natural vitamin E, E306-309), rosemary extract (E392), ascorbyl palmitate (fat-soluble vitamin C), and natural antioxidant blends effectively replace BHA. Most European and US organic/natural food brands use these alterna See the pregnancy-conscious swaps below.
