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).
The recommended adequate intake of sodium is 1,500 milligrams (3.9 g salt) per day, and people over 50 need even less." [13] The Daily Value for potassium, 4,700 mg per day, was based on a study of men who were given 14.6 g of sodium chloride per day and treated with potassium supplements until the frequency of salt sensitivity was reduced to 20%.
The recommended daily allowance of zinc is 11 mg for older men and 8 mg for older women, with an upper tolerable limit of 25–40 mg per day, including both dietary and supplemental sources. However, individuals over 60 often consume less than 50% of the recommended zinc intake, which is crucial for proper body function.
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 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 AI for fluid is 2.7L/day (91 fluid ounces, or about 11 cups) for women and 3.7L/day for men (125 fluid ounces, or about 15 cups). Recent research roughly aligns with these guidelines.
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.
