What term describes the estimates of energy and nutrients required by individuals or groups of people?

The term "nutritional requirements" accurately reflects the specific estimates of energy and nutrients that are needed by individuals or groups. Nutritional requirements take into account various factors, such as age, sex, physiological status (like pregnancy or lactation), and activity levels, to determine the appropriate amounts of energy (calories) and essential nutrients (like proteins, vitamins, and minerals) necessary for maintaining health, promoting growth, and preventing nutrition-related diseases.

This term is fundamental in nutrition science, as it helps healthcare professionals and nutritionists provide tailored dietary recommendations. Understanding these requirements allows for the creation of diet plans that meet individual needs and can support public health initiatives aimed at improving dietary habits within populations.

In contrast, nutritional assessment is a process used to evaluate an individual's dietary intake and nutritional status, but it does not specifically refer to the estimates of nutrient needs. Dietary guidelines provide overarching recommendations on healthy eating patterns and lifestyle choices, while energy intake refers to the actual amount of energy consumed through food, not the necessary estimates for maintaining good health.
