Protein Intake Supports Healthy Aging

Does adequate protein intake help you live longer and stay stronger?

Hitting the right protein targets preserves muscle, protects mobility, and supports metabolic and immune function as we age.

Explanation

Age-related muscle loss (sarcopenia) is a major driver of frailty, falls, and loss of independence. Evidence-based guidance recommends ~1.0–1.2 g protein/kg/day for healthy older adults, paired with regular resistance exercise. Distributing protein across meals helps overcome anabolic resistance and maintain lean mass. Source and quality matter — higher plant protein intake is associated with lower all-cause and cardiovascular mortality.

Practical Emphasis

Target ~1.0–1.2 g/kg/day. Spread across 3–4 meals with 25–35 g each. Pair protein with resistance training 2–3x/wk. Favor plant-forward protein patterns plus fish; limit processed meats.

Action Tip

Set a daily protein target and distribute it across meals, while strength training weekly to preserve muscle and independence.
