Vitamins, minerals and micronutrients are naturally occurring compounds with essential biological activities. Although their consumption does not provide any direct calorific return - as would be the case for macronutrients i.e. protein, fat, carbohydrate - their deficiency can have a major impact on human health. Understanding the role that such compounds play in human physiology can be greatly assisted through the study of transgenic animals, which can be engineered to mirror the disease effects seen in humans.
