Daily Nutrient Requirements for Men 71+

Every daily reference value the Dietary Reference Intakes set for men 71+: what to reach, and what not to exceed.

Protein, carbohydrate, fiber and water

NutrientDaily amountWhat it means
Protein0.8 g/kg of body weight
56 g/day at reference weight
RDA. The per-kilogram figure is the one that applies to a specific body; the gram figure is the tabulated value at this group's reference weight.
Carbohydrate130 gRDA. Set from the brain's glucose requirement, not from energy needs.
Total fiber30 gAdequate Intake. Also listed with the other nutrients in the table below.
Total water3.7 LAdequate Intake. This is total water, not glasses of water. It counts every beverage plus the moisture in food, which the DRI report puts at roughly 20% of the total. The figure is for temperate climates; heat and heavy activity raise it.

Vitamins, minerals and other nutrients

Your daily target and, where one has been set, the tolerable upper limit: the point above which intake starts carrying risk rather than benefit. "n/a" means no value has been established for this life stage.

Where these numbers come from

Vitamin and mineral values come from the NIH and NASEM-derived library used throughout this site. See the methodology page for how it is built and verified. Protein, carbohydrate, water and the macronutrient ranges are transcribed from NASEM, Dietary Reference Intakes: Macronutrients (adapted from Dietary Reference Intakes for Energy, Carbohydrate, Fiber, Fat, Fatty Acids, Cholesterol, Protein, and Amino Acids, 2002/2005) and NASEM, Dietary Reference Intakes: Electrolytes and Water (adapted from Dietary Reference Intakes for Water, Potassium, Sodium, Chloride, and Sulfate, 2004).

Educational information, not medical advice. These are population reference values for healthy people; a medical condition, a medication or a pregnancy complication can change what is right for you. Last verified August 24, 2026.
