We have been hearing for years that we need to be taking whey protein because it is very beneficial when combining diet and exercise, but why? Well, in this entry I am going to explain what exactly whey protein is and how it works!
Whey protein has a mixture of different proteins found in milk, like beta-lactoglobalin and alpha-lactalbumin. Huh? Yeah I have never heard of these either before today. After doing some research, I found that alpha-lactalbumin helps with the body’s production of serotonin. How that helps with muscle building I have no idea! Haha!
Whey protein comes in 3 forms: concentrate, isolate, and hydroslate. Concentrates are 29-89% protein by weight, and have a low level of fat, but quite a few carbs. Isolates are 90%+ protein by weight and are stripped of all fat and lactose. Hydroslates are partially hydrolized whey proteins that are easier to digest, but higher in price.
So why is whey good for you?
(1) It contains all essential amino acids required in the diet. These help with body composition and athletic performance.
(2) It has the highest levels of branched chained amino acids (BCAAs). BCAAs are the first amino acids to be used during exercise, and whey protein replenishes the body with these in order to rebuild and repair muscle!
(3) It is quickly absorbed into the body, which is why you should take it right after working out!
(4) It contains the amino acid leucine, which promotes muscle protein synthesis and muscle growth.
(5) It even helps athletes maintain a healthy immune system because it has an anti-oxidant called glutathione.
