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 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).
Micronutrients are nutrients such as vitamins and minerals required by organisms in varying quantities throughout life to orchestrate a range of physiological functions to maintain health. [1] [2] The following is a list of micronutrients used by various living organisms. For human-specific nutrients, see Mineral (nutrient).
In varying amounts supplied through the diet, micronutrients include such compounds as vitamins and dietary minerals. [3] [6] For human nutrition, micronutrient requirements are in amounts generally less than 100 milligrams per day, whereas macronutrients are required in gram quantities daily. [6]
Micronutrients are needed in smaller amounts ... women ages 20 and up consume on average 6.8 grams of alcohol per day and men consume on average 15.5 grams per day. ...
According to the U.S. Department of Agriculture, based on NHANES 2013–2014 surveys, women ages 20 and up consume on average 6.8 grams/day and men consume on average 15.5 grams/day. [92] Ignoring the non-alcohol contribution of those beverages, the average ethanol calorie contributions are 48 and 108 cal/day.
In the table above, magnesium appears to be an anomaly as the recommended intake for adult men is 420 mg/day (women 350 mg/day) while the UL is lower than the recommended, at 350 mg. The reason is that the UL is specific to consuming more than 350 mg of magnesium all at once, in the form of a dietary supplement, as this may cause diarrhea.
The current AIs for chromium for women are 25 μg/day for women ages 14–50 and 20 μg/day for older women. AI for pregnancy is 30 μg/day. AI for lactation is 45 μg/day. AI for men is 35 μg/day for ages 14–50 and 30 μg/day for older. For infants to children ages 1–13 years, the AI increases with age from 0.2 to 25 μg/day.
