Document Summary
Nutrient-based approach how much of a nutrient is required to maintain health: recommended nutrient intakes (rni) lasted until the 1980s, dietary reference intake (dri) started in the 1990s. Determined by the institute of medicine (iom) Food-based approach types and amounts of food to maintain health (e. g. , dietary pattern: canada"s official food rules was established in 1942, now called canada"s food guide. Nutrient requirement experimentally-determined requirement for a nutrient: amount required to maintain health. Nutrient intake determined by the composition of the diet: amount of nutrient consumed. To estimate the probability that an individual"s usual intake is meeting their requirement. Determine a biochemical criterion that allows you to determine the intake at which individuals requirement is being met. Determine the requirement distribution from a sample of the population: example. Vitamin x requirement is met when the level of vitamin x in serum reaches saturation. Important: this is not the universal criterion for all nutrients.
