title: Nutrient influences on toxicity and carcinogenicity.
abstract: Essential nutrients and toxicants often coexist in the diet of humans and animals. Interactions among nutrients and chemicals in the diet may alter the toxicity of the chemical or the requirement for or availability of specific nutrients. Such interactions have been demonstrated among toxins and dietary protein, trace elements, and vitamins. Certain nutrients may also alter the response to certain drugs, and some drugs, such as oral contraceptives, may alter the availability of some nutrients. The carcinogenicity of some compounds and the subsequent promotion of tumor growth are affected by nutrients such as fat, vitamins, and lipotropes and by such minor dietary constituents as naturally occurring indoles and synthetic preservatives. In this paper we review such interactions as well as the mechanisms responsible for them.
