When I talk about protein or supplements I sometimes feel special reactions: Some practitioners would tend to consider supplements as a kind of magic potion. I even knew some people who no longer ate and were only eating protein shakes all day long. Be careful, let's be clear, a protein shake is nothing like Popeye's spinach or Asterix's magic potion! For me, a protein shake is a quick and easy way to get the body the amount of protein it needs. In this protein shake, there are milk or egg that are concentrated and taste great! It simply means that the milk has been filtered, the fat has been removed and the protein kept, a flavour has been added, so you can enjoy this benefit if you don't have time to cook or take the time to eat. In the factory, for example, some workers cannot take a break to eat but they are allowed to drink. So this is the opportunity to have a protein shake.
