ALSOFOUNDINBHT (Butylated hydroxytoluene)
Restricted AbroadBHA's sibling — restricted in parts of Europe and Japan. Also listed on labels as Butylated hydroxytoluene, E321.
E-number: E321
What it is
BHA's constant companion: another synthetic antioxidant that keeps fats from going rancid, guarding cereals, chips, and gum — often from inside the packaging. If a label says one, it frequently means both.
Why it's in food
Same economics as BHA — pennies of preservative protecting months of shelf life. Manufacturers pair them because they work better together.
US vs EU status
United States
FDA-approved and everywhere — but the market moved before the regulator did: after a high-profile consumer petition in 2015, America's biggest cereal makers pledged to remove BHT from cereals, and many did. It remains legal, common in snacks and packaging, and carries none of BHA's official carcinogen listings.
European Union
Permitted as E321 at tight limits — Europe's regulator set one of its more conservative daily intakes after a 2012 review. Some countries, including Japan, restrict its uses. Unlike BHA, the WHO's cancer agency looked at BHT and filed it as 'not classifiable' — the evidence cuts both ways, with some rodent studies showing harm and others showing protective effects.

- Chips, crackers, and snack mixes
- Chewing gum
- Shortening and packaged baked goods
- Package liners — 'BHT added to packaging to preserve freshness'

Cleaner swaps

- Rosemary extract
- Brands labeled 'No BHA/BHT'
Case note
BHT rides in BHA's shadow — same cereal bags, same job, lighter rap sheet — and this library says so, because a board that can't tell its suspects apart isn't worth trusting. The real story in this file is who removed it: not regulators. Customers. Files close faster at the register than at the FDA.
FAQ
Is BHT as bad as BHA?
By the official records, no. BHA carries the WHO's 'possibly carcinogenic' label, the US NTP designation, and a Prop 65 listing; BHT carries none of them — the WHO filed it as 'not classifiable' because the animal evidence is genuinely mixed. They're convicted-adjacent, not co-defendants. This library stamps them differently on purpose.
Why do cereal bags mention BHT in the packaging?
Because that's often where it lives — sprayed into the liner so it migrates slowly and keeps the contents fresh. US labeling handles this with the phrase 'BHT added to packaging to preserve freshness.' It's one of the rare cases where a package honestly announces an additive you're not technically eating on purpose.
Why did cereal companies remove BHT?
Customers asked. A 2015 petition put BHT on the front page, and within weeks major manufacturers pledged reformulation — vitamin E does the same job at slightly higher cost. No law changed. It's the cleanest recent proof that in the US, files close faster at the cash register than at the FDA.
Is BHT banned anywhere?
Not banned outright in major markets — restricted is the accurate word: narrow permitted uses in Japan, low dose caps in the EU. If you're avoiding it, the label word is BHT, and remember its favorite hiding spot is the packaging line, not the ingredient list.
