21.4: Energy and Macronutrients

The energy requirements for ages thirty-one to fifty are 1,800 to 2,200 calories for women and 2,200 to 3,000 calories for men, depending on activity level. These estimates do not include women who are pregnant or breastfeeding. Middle-aged adults must rely on healthy food sources to meet these needs. Following the middle-aged years,’ dietary guidelines provide adequate but not excessive energy, macronutrients, vitamins, and minerals. Typical dietary patterns in many parts of North America do not match the recommended guidelines.

The AMDRs for carbohydrates, protein, fat, fiber, and fluids remain the same from young adulthood into middle age. It is important to avoid putting on excess pounds to help prevent cardiovascular disease, diabetes, and other chronic conditions.
