From Report on Health and Social Subjects: no. 41. Dietary reference values for food energy and nutrients for the United Kingdom. Report of the Panel on Dietary Reference Values of the Committee on Medical Aspects of Food Policy. London: Her Majesty’s Stationery Office, 1991. This is the U.K.’s Report Table 1-4.

^aThe Reference Nutrient Intake is a point in the distribution that is two notional standard deviations above the Estimated Average Requirement (EAR). Intakes above this amount will almost certainly be adequate.

^bBased on protein providing 14.7% of EAR for energy.

^cAfter age 65 the RNI is 10 µg/day for men and women.

^dFor last trimester only.

^eNo increment.
