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 (RDAs, see below).
Women need, on average, 1800–2200 kilocalories (kcal) a day whereas children need 1500–2000 kcal and men 2200–2700 kcal. [2] In March 2009, the European Food Safety Authority published its opinion on intake levels for Europe and they were consistent with numbers behind the GDAs developed in the UK. [10] Moreover, not all categories are equal.
The guideline salt intake for adults is about 6 grams of salt (approximately one teaspoon). The Food Standards Agency estimate the average salt intake is about 8.6 grams/day [6] (2008). 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.
The RDAs (and later the RDA values within the DRI) were regularly revised to reflect the latest scientific information, but although the nutrition labeling regulations were occasionally updated, the existing RDI values were not changed, so that until 2016, many of the DVs used on nutrition facts labels were still based on the outdated RDAs from ...
This data is presented in kilojoules, as most countries today use the SI unit kilojoules as their primary measurement for food energy intake, [4] with the exception of the USA, [5] Canada, [6] and the UK, which use kilocalories or both. [7]
The Dietary Guidelines for Americans recommend limiting alcoholic beverages consumption to no more than 1 drink daily for women and no more than 2 drinks daily for men. The 2015–2020 Scientific Report of the Dietary Guidelines Advisory Committee asserts that most studies show that moderate consumption of alcohol has been shown to be part of a ...
The Schofield Equation is a method of estimating the basal metabolic rate (BMR) of adult men and women published in 1985. [1] This is the equation used by the WHO in their technical report series. [2] The equation that is recommended to estimate BMR by the US Academy of Nutrition and Dietetics is the Mifflin-St. Jeor equation. [3]
The Stigler diet is an optimization problem named for George Stigler, a 1982 Nobel laureate in economics, who posed the following problem:. For a moderately active man weighing 154 pounds, how much of each of 77 foods should be eaten on a daily basis so that the man’s intake of nine nutrients will be at least equal to the recommended dietary allowances (RDAs) suggested by the National ...
