Food toxicology deals with how natural or synthetic poisons and toxicants in various food products cause harmful, detrimental, or adverse side effects in living organisms. Food Toxicology shields with various aspects of food safety and toxicology, including the study of the nature, properties, effects, and detection of toxic substances in food and their disease manifestations in humans. It will also include other phases of consumer product safety. A food toxicologist studies toxicants in food, the health effects of high nutrient intakes, and the connection between toxicants and nutrients. Food and nutrition toxicology involves investigation of flavours, additives packaging materials and food contaminants.
