Nutrition and dietary carcinogens

Immunoaffinity purification of dietary heterocyclic amine carcinogens.

Cooking meats produces a family of heterocylic aromatic amines that are carcinogens in rodents and genotoxic in many short-term assays. Concern that these compounds may be human carcinogens has prompted us to develop immunochemical methods for quantifying these compounds in the human diet and for identifying the parent compounds and metabolites in urine and feces. Previously reported monoclonal...

Elephants: Nutrition and Dietary Husbandry

Elephants are the largest extant herbivores on earth. Although the average weight of adult Asian elephants (Elephas maximus) tends to be less than that of adult African elephants (Loxodonta africana), in the wild their weight ranges overlap (Asian, 1,800-5,000 kg [4,000-11,000 lb]; African, 1,800-6,000 kg [4,000-13,000 lb]) and are influenced by age, sex, health, and food supply. Their nutrient...

Effects of dietary constituents on the metabolism of chemical carcinogens.

Dietary constituents of 2 types have been shown to affect the metabolism of chemical carcinogens by the microsomal mixed-function oxidase system. Naturally occurring inducers of increased activity of this system are present in plants. Cruciferous vegetables including Brussels sprouts, cabbage, and cauliflower are relatively potent in this regard. From these vegetables, three indoles with induci...
