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).
The Dietary Goals also recommended increasing complex carbohydrates and naturally occurring sugars from 28% to 48% of energy intake, reducing refined and processed sugars to about 10% of energy intake, reducing fat from 40% to 30% of energy intake, reducing eating saturated fat to 10% of energy intake, reducing cholesterol consumption to 300 ...
The recommended maximum daily intake of sodium – the amount above which health problems appear – is 2,300 milligrams per day for adults, about 1 teaspoon of salt (5.9 g). 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 protein requirement for each individual differs, as do opinions about whether and to what extent physically active people require more protein. The 2005 Recommended Dietary Allowances (RDA), aimed at the general healthy adult population, provide for an intake of 0.8 grams of protein per kilogram of body weight. [43]
Women should aim to eat 25-28 grams of fiber and men should eat about 28 grams, but because 95% of Americans don’t eat enough fiber, more is generally better for healthy people.
The guideline recommends that both adults and children reduce the intake of free sugars to less than 10% of total energy intake. [15] In 2016, added sugar was added to the revised version of the nutrition facts label and was a given a daily value of 50 grams or 200 calories per day for a 2,000 calorie diet. [16] [17]
To put this in context, most 12-US-fluid-ounce (355 ml) cans of soda contain 39 grams of sugar. In the United States, a government survey on food consumption in 2013–2014 reported that, for men and women aged 20 and older, the average total sugar intakes—naturally occurring in foods and added—were, respectively, 125 and 99 g/day. [154]
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.
