Protein is in many of the foods
that we eat every day, but for something so common, it’s often a
misunderstood part of our diets. Think of protein and you might think of
a huge piece of steak sizzling on a grill, the latest energy bar
touting to banish fatigue, or a protein shake promising to fuel amazing
muscle growth. Yes, these foods are all packed with protein, but when it
comes to making the best protein choices to keep your body and mind
healthy,
quality is just as important as
quantity.
What is protein?
Protein is a vital nutrient required for
building, maintaining, and repairing tissues, cells, and organs
throughout the body. Every cell in your body contains protein and it is a
major part of the skin, hair, and nails. Protein forms body chemicals,
such as enzymes, that are responsible for the many metabolic processes
that sustain life. When you eat protein in food, it is broken down into
the 20 amino acids that are the body’s basic building blocks for growth
and energy. The amino acid tryptophan influences mood by producing
serotonin, which can reduce symptoms of depression and anxiety and
improve overall cognitive function.
