As a matter of fact, they do. A recent study compared the published research (23 studies) comparing the calories and nutrients of elderly people with and without sarcopenia. Sarcopenia is a condition, which is characterized by the loss of muscle mass and strength, as a result of aging.
The study found out that both the average number of calories and amounts of nutrients were significantly lower in older people with sarcopenia compared with those without sarcopenia. The investigated nutrients were macronutrients (proteins, carbohydrates and saturated fatty acids) as well as micronutrients, such as minerals (calcium, magnesium, sodium, selenium) and vitamins (A, B12, C, and D).
This information can help in adjusting the diet of aging people and together with exercise helps to prevent sarcopenia.
