As we age, our nutritional needs don’t simply continue on the same trajectory. Several important shifts occur after age 60 that change how much of certain nutrients we need, how well we absorb them, and what deficiencies we’re most at risk of developing. Understanding these changes is the first step toward eating in a way that genuinely supports health in later life.
Protein needs increase with age
Contrary to what many people assume, older adults actually need more protein, not less. This is due to anabolic resistance — a reduced efficiency in how aging muscles respond to protein signals. To maintain muscle mass (and with it, strength, balance, and metabolic health), adults over 60 typically need 1.2–1.6 grams of protein per kilogram of body weight daily — significantly higher than the general adult recommendation of 0.8g/kg. High-quality sources include eggs, fish, lean poultry, legumes, dairy, and tofu.
Calcium and vitamin D become critical
Bone loss accelerates significantly after 60, particularly in post-menopausal women. Calcium (1,200mg/day for women over 50 and men over 70) and vitamin D (800–2,000 IU/day) work together to maintain bone density and reduce fracture risk. Dietary sources of calcium include dairy, fortified plant milks, canned fish with bones, and leafy greens. Vitamin D is synthesized through sun exposure but becomes less efficient with aging skin; supplementation is often necessary.
B12 absorption decreases
Vitamin B12 absorption depends on gastric acid and a protein called intrinsic factor. With aging, stomach acid production often decreases — a condition called achlorhydria — impairing B12 absorption from food. Deficiency causes nerve damage, memory problems, and anemia, and can be mistaken for dementia. Older adults are advised to prioritize crystalline B12 (found in supplements and fortified foods) which doesn’t require gastric acid for absorption.
Appetite and calorie needs decrease, but nutrient needs don’t
Metabolic rate slows with age, meaning calorie needs decrease. But micronutrient requirements remain the same or increase. This creates a nutritional squeeze: older adults need to get the same or more vitamins and minerals from fewer total calories. The solution is nutrient density — prioritizing whole, minimally processed foods that deliver maximum nutrition per calorie.
Dehydration risk increases
The sensation of thirst diminishes with age, increasing the risk of chronic dehydration. This can cause confusion, constipation, urinary tract infections, and falls. Older adults are advised to drink fluids consistently throughout the day regardless of thirst, and to include high-water foods (soups, fruits, vegetables) as a reliable hydration strategy.
