Preservatives BHA and BHT: BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene) are common preservatives in foods like cereal, nut mixes, chewing gum, butter spread, meat and beer. The National Toxicology Program’s 2011 Report on Carcinogens says BHA may trigger allergic reactions and hyperactivity and “is reasonably anticipated to be a human carcinogen.” Both are banned in parts of the European Union and Japan; the UK doesn’t allow BHA in infant foods.
