Dietary Reference Intakes (DRIs) represent a comprehensive set of reference values for the amounts of nutrients and other dietary components needed for maintaining health and preventing chronic diseases. These values serve as a scientific basis for the evaluation of dietary intake in different populations. They include several types of recommendations, such as RDA (Recommended Dietary Allowance), AI (Adequate Intake), EAR (Estimated Average Requirement), and TUL (Tolerable Upper Intake Level), which help health professionals, including dietetic technicians, assess and understand individual and group nutrient needs.

In contrast, measuring physical activity levels, guidelines for food preparation techniques, and types of food groups recommended daily do not fall under the category of DRIs. Physical activity levels are assessed through different guidelines related to exercise and movement, while food preparation techniques are addressed in culinary education and nutrition practices, and food group recommendations pertain to dietary patterns rather than specific nutrient intake levels. Thus, the DRI's focus on nutrient reference values distinctly positions it as an essential tool in dietary assessment and nutrition planning.
