Some of the chemicals highlighted in the guide are not allowed for use in food in the European Union, including potassium bromate, a carcinogenic bread additive, and brominated vegetable oil, a flavor stabilizer used in beverages that can harm the nervous system.

We especially recommend avoiding foods with synthetic colorants, known as FD&C colorants. Dietary exposure to these colorants can lead to changes in the nervous system, such as an increased risk of attention deficit disorders and other neurobehavioral changes in children. Foods sold in Europe that carry several of these colorants must carry a warning stating they may harm activity and attention in children.

In addition to additives in the ingredient list on the food label, potentially harmful chemicals can migrate into food from food packaging and end up in our diet.

Such materials include PFAS, the family of fluorinated chemicals that can harm the developing fetus, suppress the immune system and cause other health harms. PFAS are added to packaging to make it slick and nonstick. Other food packagings chemicals, such as phthalates and bisphenol A, can disrupt the normal function of the endocrine system and affect reproductive system development.
