We need protein for our muscles, bones, hormones, immune system, digestive enzymes, nutrient absorption and to rebuild and replenish all kinds of cells. Protein consists of 20 amino acids, some of which we can synthesize ourselves while 9 of them are “essential” — meaning we need to get them from our diet. If you don’t get enough protein, you can lose muscle mass which can lead to increased falls, injuries or hospitalizations. While overt protein deficiencies are rare, even a suboptimal status can take a toll on our health!
