The 2026-2030 U.S. Dietary Guidelines for Americans (released Jan 2026) significantly increase recommended protein intake for seniors to 1.2–1.6 grams per kilogram of body weight daily (approx. 0.5–0.7 grams per pound) to combat age-related muscle loss (sarcopenia) and support metabolic health. This is a, ~50% increase over previous, minimum standards. It also encouraging consumption of red meat, poultry, and seafood as part of a balanced diet.
Protein is very important for active healthy adults and elderly, for maintain overall body functioning, muscle strength, and resilience. However, protein insufficiency is common in aging population. As many at middle-age or after modify their diet due to weight and cholesterol concerns, but neglected protein intake. Other reasons may include physiological aging changes, such as lack of appetite, inactivity, dental health, etc.
Aging is associated with a progressive decline in resting metabolic rate (RMR). Up to 50% of total body weight in young adults is lean muscle mass but this declines with aging to 25% when reaching an age of 75–80 years. As aging will lose muscle mass, protein needs of older adults increase for their muscle functioning and strength. The National Institute of Health recommends that 10-35% of calories should be from protein, regardless of total calorie intake.

Take home messages:
- Proteins are the main building blocks of the human body. Best protein source is from balanced diet.
- As aging will lose muscle mass, protein needs of older adults increase for maintain muscle functioning and strength, combined with exercise and resistant training.
- Animal-based (complete) protein include casein, whey, and collagen and plant-based (incomplete) protein include soy, pea, rice, and hemp.
- A variety of protein supplements are available and may be used for personal goals of muscle building, weight loss or nutritional needs.
- Whey protein powder is generally safe and well tolerated at recommended dosage
- Follow the new 2026 Dietary Guidelines for Americans and increase protein intake
- Track protein intake self-evaluation and adjustment
- Get start or continue exercise routine with resistant training
