The Dietary Reference Intake ( DRI ) is a system of nutrition recommendations from the National Academy of Medicine (NAM) of the National Academies (United States) . It was introduced in 1997 in order to broaden the existing guidelines known as Recommended Dietary Allowances ( RDA s, see below). The DRI values differ from those used in nutrition labeling on food and dietary supplement products in the U.S. and Canada, which uses Reference Daily Intakes (RDIs) and Daily Values (%DV) which were based on outdated RDAs from 1968 but were updated as of 2016.
18-486: DRI provides several different types of reference values: DRIs are used by both the United States and Canada, and are intended for the general public and health professionals. Applications include: The European Food Safety Authority (EFSA) refers to the collective set of information as Dietary Reference Values , with Population Reference Intake (PRI) instead of RDA, and Average Requirement instead of EAR. AI and UL define
36-450: A "margin of safety". Because of food rationing during the war, the food guides created by government agencies to direct citizens' nutritional intake also took food availability into account. The Food and Nutrition Board subsequently revised the RDAs every five to ten years. In the early 1950s, United States Department of Agriculture nutritionists made a new set of guidelines that also included
54-526: A committee established by the United States National Academy of Sciences in order to investigate issues of nutrition that might "affect national defense". The committee was renamed the Food and Nutrition Board in 1941, after which they began to deliberate on a set of recommendations of a standard daily allowance for each type of nutrient. The standards would be used for nutrition recommendations for
72-506: A higher standard of evidence to be utilized when making dietary recommendations. The only DRIs to have been revised since that meeting until 2011 are vitamin D and calcium. Percent of U.S. population ages 2+ meeting EAR or USDA healthy eating patterns in 2004 Dietary Reference Values Dietary Reference Values (DRV) is the name of the nutritional requirements systems used by the United Kingdom Department of Health and
90-730: Is given for healthy people using the table. The British government recommended that healthy people should eat a diet which contains plenty of starch (rice, bread, pasta and potatoes). It also recommends that a person should eat at least 5 fruit or vegetable portions each day. Meat, fish, eggs and other protein-rich foods should be eaten in moderation. Dairy products should also be moderately consumed. Finally, salt, saturated fat and sugar should be eaten least of all. Exceptions to these rules include pregnant women and young children. Additionally, those who have little exposure to sunlight may need to take vitamin D supplementation. The Dietary Reference Values below are specified mainly for adults. They define
108-460: Is recommended that intake from these nutrients be from food only, to prevent adverse effects. It is also recommended that the following substances not be added to food or dietary supplements. Research has been conducted into adverse effects, but was not conclusive in many cases: RDA/AI is shown below for males and females aged 19–50 years. The equations used to calculate the RDA are as follows: "If
126-604: Is searching for comments (Open Consultation) by 15 October, in order to validate its assumptions on the need to have: EFSA considers that there are not sufficient data to set DRVs for sugars, and not systematic scientific substantiation linking diseases such as stroke or diabetes (DMT1 or DMT2) to an increased intake of sugars (glycemic load/glycemic index). In any case, there is much literature referring to this link, on journals with very high impact factor and statistically robust design and results Many problems seem nowadays to derive from having integrated EU level DRV: General advice
144-512: The standard deviation (SD) of the EAR is available and the requirement for the nutrient is symmetrically distributed , the RDA is set of two SDs above the EAR: R D A = E A R + 2 S D ( E A R ) {\displaystyle RDA=EAR+2SD(EAR)} If data about variability in requirements are insufficient to calculate an SD, a coefficient of variation (CV) for
162-463: The EAR of 10 percent is assumed, unless available data indicate a greater variation in requirements. If 10 percent is assumed to be the CV, then twice that amount when added to the EAR is defined as equal to the RDA. The resulting equation for the RDA is then R D A = 1.2 E A R {\displaystyle RDA=1.2EAR} This level of intake statistically represents 97.5 percent of
180-734: The European Union's European Food Safety Authority . In 1991, the United Kingdom Department of Health published the Dietary Reference Values for Food Energy and Nutrients for the United Kingdom . This records Dietary Reference Values which recommended nutritional intakes for the UK population. The DRVs can be divided into three types: RNI is not the same as RDA (Recommended Daily Allowance) or GDA , although they are often similar. In recent times, Dietary Reference Values are under
198-491: The armed forces, for civilians, and for overseas population who might need food relief. Roberts, Stiebeling, and Mitchell surveyed all available data, created a tentative set of allowances for "energy and eight nutrients", and submitted them to experts for review (Nestle, 35). The final set of guidelines, called RDAs for Recommended Dietary Allowances, were accepted in 1941. The allowances were meant to provide superior nutrition for civilians and military personnel, so they included

A high salt diet is likely to increase the risk of high blood pressure, which is associated with an increased risk of heart attack and stroke. Recommendations for protein, vitamins and minerals vary by age. Where different intakes for males and females are recommended, the higher value is identified in the table below to ensure that the greatest daily needs of
234-837: The interest of the European Food Safety Authority too, which intend to extend them at the EU level. EFSA is the equivalent of the Food and Drug Administration (FDA) in the USA, and acts as watchdog inside the European market in order to establish a common ground on food safety requirements and nutrition as well. EFSA met in September 2009 with representative of the Member States in order to gain their views on fats, carbohydrates, fibres and water as well as Food-Based Dietary Guidelines. Furthermore EFSA
252-412: The number of servings of each food group in order to make it easier for people to receive their RDAs of each nutrient. The DRI was introduced in 1997 in order to broaden the existing system of RDAs. DRIs were published over the period 1998 to 2001. In 2011, revised DRIs were published for calcium and vitamin D. Additionally, revised DRIs were published for potassium and sodium in 2019. The DRI for energy
270-426: The proportion of a person's total energy intake which should come from different components of food. These include fat and fatty acids, fibre, starch and sugars. These values do not apply to children, and children younger than five with small appetites should not have such restrictions imposed. The guideline salt intake for adults is about 6 grams of salt (approximately one teaspoon). The Food Standards Agency estimate
288-521: The requirements of the population." In September 2007, the Institute of Medicine held a workshop entitled "The Development of DRIs 1994–2004: Lessons Learned and New Challenges". At that meeting, several speakers stated that the current Dietary Recommended Intakes (DRI's) were largely based upon the very lowest rank in the quality of evidence pyramid , that is, opinion, rather than the highest level – randomized controlled clinical trials. Speakers called for
306-492: The same as in the United States, although numerical values may differ. Australia and New Zealand refer to the collective set of information as Nutrient Reference Values, with Recommended Dietary Intake (RDI) instead of RDA, but EAR, AI and UL defined the same as in the United States and Canada, although numerical values may differ. The recommended dietary allowance (RDA) was developed during World War II by Lydia J. Roberts , Hazel Stiebeling , and Helen S. Mitchell , all part of
324-489: Was updated in 2023. None of the other DRIs have been revised since first published 1998 to 2001. Highest EARs and RDA/AIs and lowest ULs for people ages nine years and older, except pregnant or lactating women. ULs for younger children may be lower than RDA/AIs for older people. Females need more iron than males and generally need more nutrients when pregnant or lactating. NE : EARs have not yet been established or not yet evaluated; ND : ULs could not be determined, and it
