Abstract
The aging process is frequently characterized by an involuntary loss of muscle
(sarcopenia) and bone (osteoporosis) mass. Both chronic diseases are associated
with decreased metabolic rate, increased risk of falls/fracture, and, as a
result, increased morbidity and loss of independence in the elderly. The
quality and quantity of protein intake affects bone and muscle mass in several
ways and there is evidence that increased essential amino acid or protein
availability can enhance muscle protein synthesis and anabolism, as well as
improve bone homeostasis in older subjects. A thorough evaluation of renal
function is important, since renal function decreases with age. Finally,
protein and calcium intake should be considered in the prevention or treatment
of the chronic diseases osteoporosis and sarcopenia.
