Axel Sigurdsson, MD, PhD, published a great article on prevention of age-related sarcopenia (loss of muscle mass). Click through for details. To stay vigorous as you age, you want to preserve muscle mass and the strength it provides. If you’ve lost muscle mass, you can re-build it. Summary from the good doctor:
Age-related loss of muscle mass (sarcopenia)may start as early as in our thirties and appears to continue for the rest of our lives.
There is also a loss of muscle strength and muscle function. The consequences may often be severe, particularly in the elderly.
Increased physical activity and adequate nutrition are the most powerful tools at our disposal to delay age-related loss of muscle mass.
Well-rounded exercise programs consisting of aerobic and resistance exercises are believed to be most effective
Modification of dietary habits may be an important tool to prevent the decline in muscle mass and function that occurs with aging.
Adequate protein intake is of key importance. Animal-derived protein may provide a higher and broader biological value than vegetable protein.
Fish consumption is recommended and fruits and vegetables should be consumed regularly.
Nutritional supplements containing essential amino acids may be helpful. This is particularly true for whey protein.
Fish-derived protein hydrolysates also appear promising.
Adequate intake of vitamin D is essential.
“Fish-derived protein hydrolysates” doesn’t sound very appetizing. I’ll stick with whole fish for now, especially cold-water fatty fish.
