What Is Whey Protein?
Cow Milk actually contains two main types of protein: casein (80%) and whey (20%).
The protein in human milk is 60% whey and 40% casein.
Whey is found in the watery portion of milk. When cheese is produced, the fatty parts of the milk coagulate and the whey is separated from it as a byproduct
If you’ve ever opened a yogurt container to see liquid floating on top — that’s whey.
After being separated during cheese production, whey goes through various processing steps to become what people generally recognize as whey protein — a powder that is added to shakes, meal replacements and protein bars.
Why whey protein?
Whey protein is far superior to all other forms of protein. It provides the body with the perfect amino acid profile for muscle building, strength and recovery. Bodybuilders and professional athletes all know the importance of using whey protein supplements to help increase size, strength and speed up recovery times.
Whey is also fast ingesting, meaning it gets to where it’s needed – fast! Whey protein supplements play a huge roll in post-workout nutrition, when your body is in a catabolic state and needs a fast injection of protein.
On top of the muscle building and recovery benefits, whey protein also works as an antioxidant to boost the body’s immune system. Scientific studies have shown that regular supplementation with whey protein promotes a strong immune system.
How whey protein is made?
Whey protein is made during the process of producing cheese. Special enzymes are added to the milk to create the separation of curds and the liquid whey.
The liquid whey is then pasteurized and dried into a powder form.
Whey protein supplements generally fall into three categories;
- Whey protein isolate – the most pure form of whey protein
- Whey protein concentrate – not as pure, slightly higher fat & lactose
- Whey protein blend – a mixture of isolate and concentrate
Are there risks of consuming whey protein?
For starters, it can give you acne. Whey can mess with the production of acne-causing hormones, insulin and androgens, which can overstimulate sebum production and oil glands that cause acne.
It could also give you some stomach issues.”Any dairy susceptible individuals—like those that are lactose intolerant—may experience gas, bloating, and diarrhea from too much whey,” says Auslander Moreno.
