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.
