  • You're listening to life kit from NPR.

  • Hey, everyone, this is Regina Barber, and I'm in for Mariel Saguera.

  • I've been thinking about protein a bit lately.

  • Like, should I eat less meat because a more plant based diet is healthy?

  • Would it be better for the environment?

  • And if I do do that, am I going to get enough protein?

  • Am I getting enough protein?

  • Now, my colleague Allison Aubrey has been looking into all this for her series, how to thrive as you age, and she's NPR's food and health correspondent.

  • Protein is important because muscle mass is important.

  • Now, muscle mass peaks in our thirties, and then it starts this long, slow decline.

  • And maintaining muscle mass isn't just so people can look buff.

  • There's a real risk.

  • More than 45% of older adults in the US, especially women, are affected by loss of muscle, a condition that has a pretty fancy medical name, sarcopenia.

  • And I kind of like using this name because it sounds scary, and I think it is scary.

  • I mean, muscle loss is a key risk factor for falling, which is actually the top cause of death from injury in older people.

  • But thankfully, there's something you can do to prevent this slow decline.

  • We need to use our muscles, and we need to feed our muscles what they need to thrive, which is plenty of protein.

  • But how much protein are we talking about here?

  • Can we eat too much of it?

  • And what kind of exercises can help with all of this?
