The Dietary Reference Intake (DRI) is a system of nutrition recommendations from the National Academy of Medicine (NAM) [a] of the National Academies (United States). [1] It was introduced in 1997 in order to broaden the existing guidelines known as Recommended Dietary Allowances ( RDA s, see below).
In the U.S. and Canada, the Reference Daily Intake (RDI) is used in nutrition labeling on food and dietary supplement products to indicate the daily intake level of a nutrient that is considered to be sufficient to meet the requirements of 97–98% of healthy individuals in every demographic in the United States.
The Harris–Benedict equation (also called the Harris-Benedict principle) is a method used to estimate an individual's basal metabolic rate (BMR).. The estimated BMR value may be multiplied by a number that corresponds to the individual's activity level; the resulting number is the approximate daily kilocalorie intake to maintain current body weight.

Colon health: A diet rich in fiber is associated with a lower risk of developing colorectal cancer. Gut microbiome support: Fiber acts as a prebiotic, promoting the growth of healthy bacteria in ...
The Recommended Dietary Allowances (RDAs) are scientifically determined levels of essential nutrient intake, deemed sufficient by the Food and Nutrition Board to meet the nutritional needs of nearly all healthy individuals. The first RDAs were published in 1943, during World War II, with the aim of setting standards for optimal nutrition. The ...
Researchers adjusted their findings to account for variables such as age, body mass index (BMI), smoking status, total calorie intake, as well as other dietary patterns using the Alternative ...
It is the equation which is behind the 2005 Dietary Guidelines for Americans and the new food pyramid, MyPyramid. The Institute of Medicine equation uses a different approach to most others. The equation doesn't measure basal metabolic rate , but uses experiments based on doubly labelled water .
