The Dirty List

Butylated hydroxytoluene (BHT) is a synthetic antioxidant derived from petroleum, used to prevent fats and oils from going rancid in processed foods and packaging. It is closely related to BHA (butylated hydroxyanisole), and the two are often used together. BHT is also used in non-food industrial applications, which is one reason many people prefer to limit it in their diet.

Found In:

Breakfast cereals (especially flaked and puffed varieties)
Chewing gum
Chips, crackers, and snack mixes
Butter and shortening
Instant mashed potatoes and dehydrated foods
Food packaging and cereal box liners (migrates into food)
Cosmetics and personal care products

Health Impact:

The National Toxicology Program has found that BHT’s close relative BHA is reasonably anticipated to be a human carcinogen, and BHT has shown similar concerns in animal studies. Research published in the Journal of the American College of Toxicology showed BHT can cause liver and kidney enlargement at moderate doses in rodents. A 1986 study in Carcinogenesis found BHT had tumor-promoting activity in certain organ systems while showing protective effects in others, making it unpredictable. Some animal studies have also examined whether BHT may affect thyroid hormone and reproductive measures, though the findings are mixed and come mostly from high-dose research. Many countries have restricted or banned BHT in food, but it remains fully permitted in the U.S.

Healthier Alternatives:

Cereals and snacks preserved with tocopherols (vitamin E)
Brands that explicitly state “no BHT” or “no artificial preservatives”
Whole-grain oats and homemade granola instead of boxed cereals
Fresh-baked goods from bakeries using simple ingredient lists
Nuts, seeds, and dried fruit as snack alternatives

Scientific Evidence:

National Toxicology Program (NTP, 2021): BHA (closely related to BHT) listed as “reasonably anticipated to be a human carcinogen” in the Report on Carcinogens
Ito et al. (1986, Carcinogenesis): BHT showed tumor-promoting activity in rodent liver and urinary bladder models
Lanigan & Yamarik (2002, Journal of the American College of Toxicology): Review documenting liver and kidney effects of BHT at moderate doses in animal studies
Pop et al. (2013, Clujul Medical): BHT demonstrated endocrine-disrupting activity, interfering with thyroid hormone levels and reproductive parameters in animal models

Know This ⚠️

Quick Swaps

❌ Boxed cereal with BHT in the packaging liner → ✅ Rolled oats, muesli, or cereals labeled "no BHT"
❌ Chewing gum with BHT → ✅ Natural gum brands (Simply Gum, Pur)
❌ Snack crackers preserved with BHT → ✅ Simple ingredient crackers (Mary's Gone Crackers, Flackers)

Check the cereal box. "BHT added to packaging" still means BHT in your food.
