By 2030, one in five Americans will be over 65. Yet nearly half of seniors in the US aren’t getting enough protein — and most don’t know it. Malnutrition in older adults doesn’t look like starvation. It looks like fatigue, frequent falls, brain fog, and slow wound healing.
The right nutrition can change that trajectory completely.
The Protein Problem Nobody Talks About
After 65, your body becomes less efficient at using protein to build and maintain muscle. The result is sarcopenia — age-related muscle loss that raises fall risk, limits mobility, and accelerates frailty.
The PROT-AGE Study Group recommends 0.45–0.54g of protein per pound of body weight daily for adults over 65 — significantly more than standard guidelines. Spread it across all meals, not just dinner. Best sources: eggs, Greek yogurt, salmon, cottage cheese, beans, lentils, and tofu. Resistance exercise alongside adequate protein can help preserve strength even into your 70s and 80s.
The Supplements Seniors Actually Need
Generic multivitamins often miss the mark. As you age, stomach acid decreases, directly impairing absorption of key nutrients. Focus blood tests and supplementation on:
- Vitamin B12 — absorption drops with age and is further reduced by common medications like metformin and acid reflux drugs; deficiency links to nerve damage and cognitive decline
- Vitamin D — essential for bone strength, immune function, and muscle performance; most seniors are deficient due to reduced sun exposure
- Calcium — better absorbed from food (dairy, fortified plant milk, leafy greens) than high-dose supplements
- Omega-3 fatty acids — support brain, heart, and anti-inflammatory health; algae-based options work for plant-based seniors
Plant-Based Diets: Benefits and Blind Spots
A plant-forward diet is genuinely beneficial for seniors — lower chronic disease risk, better cholesterol, more fibre. But it requires deliberate planning. B12 is found only in animal foods or fortified products. Combine complementary proteins (beans + rice, lentils + nuts) and always consult your doctor before going fully plant-based.
