Recommended nutrient intakes are based on WHO guidelines (204) for all nutrients other than phosphorus and copper, which are based on recommendations from the US Institute of Medicine (205). Because the recommended nutrient intakes differ by age and sex, population-level average values were calculated using the age and sex structure based on data from the Global Burden of Disease project and forward projections by the UN Population Division. Estimates of recommended energy intake account for the age- and sex-specific energy needs for a moderately active population with US height as an upper bound and include the energy costs of pregnancy and lactation.
