BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene) are commonly used preservatives that can be found in breakfast cereal, nut mixes, chewing gum, butter spread, meat, dehydrated potatoes, and beer, just to name a few.
BHA is known to cause cancer in rats, and may be a cancer-causing agent in humans as well. In fact, according to the US Department of Health and Human Services, National Toxicology Program’s 2011 Report on Carcinogens, BHA “is reasonably anticipated to be a human carcinogen.” It may also trigger allergic reactions and hyperactivity, while BHT can cause organ system toxicity.
Where it’s banned: The UK doesn’t allow BHA in infant foods. BHA and BHT are also banned in parts of the European Union and Japan.
