Did you ever see those grim images of protein-starved children in faraway places? “Good thing that stuff doesn’t happen here,†you mutter under a sigh of relief.
Newsflash: Protein malnutrition is closer to home than you could imagine, particularly in seniors with dwindling food intake who may not eat enough protein-rich foods.
Protein is made up of amino acids — the building blocks for muscle, enzymes, and cell structure inside the body. But here is the catch: The body does not store extra amino acids and cannot produce several so-called essential amino acids.  So what’s a protein-starved body to do? You must eat enough protein and the right types everyday to keep adequate supplies flowing. If that is not possible then protein supplements can be a valuable option.
Without enough protein intake the body swipes needed building blocks from muscles. Each decade over age 50, in fact, you can lose another 10% of your muscle mass. This weakens the body and could affect strength, balance and daily function. The infection-fighting immune system and oxygen-carrying hemoglobin in red blood cells also depend on protein. Clearly you cannot short-change protein intake for your body.
How Much Protein is Enough?
Adults age 19 to 59 years old:Â Daily need is about 8 grams protein for each 20 pounds body weight
Older adults over 60: Daily need is about 10 to 13 grams protein for every 20 pounds of body weight.
For example, a 120 pound woman who is 72 years old would need between 10 and 13 grams of protein for each 20 pounds body weight. 20 x 6 = 120 lbs. So she would 60 to 78 grams of protein to meet her daily requirements (6 x 10 = 60, 6 x 13 = 78).
Just choose several items from the chart below and add them up to reach your daily protein requirement – and you are well on your way to maintaining your independence as you age.
