Everyone needs protein. Period. It is not just the big muscular gym guy, also you sitting in the chair diligently doing your job or you running a half-marathon or you playing football. Why? Because proteins are the brickstones of our body, they are the catalysators (= enzymes) of our metabolism and are also fuel. To say it in numbers: after water (70%), proteins (18%) are the second main component of human cells. That’s why it may be worth considering adding more protein to your daily food, especially if you are getting serious about living a more active and healthy lifestyle.
