What Is Whey Protein?
Whey protein is a mixture of proteins isolated from whey, which is the liquid part of milk that separates during cheese production.
Milk actually contains two main types of protein: casein (80%) and whey (20%).
Whey is in the aqueous portion of milk. When the cheese is produced, the fat parts of the milk coagulate and the whey is separated from it as a by-product.
If you have already opened a yogurt container to see the floating liquid on the top, this is whey. The cheese makers used to discard them before they discovered its commercial value.
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.
Whey protein does not taste very good on its own, which is why it is usually flavored. Chocolate flavored powders, vanilla and strawberry are very popular.
It is important to read the list of ingredients, as some products may have unhealthy additives such as refined sugar.
Taking whey protein is a convenient way to add 25 to 50 grams of protein on top of your daily intake.
This can be important for bodybuilders and gym enthusiasts, as well as people who need to lose weight or are simply lacking protein in their diet.
Most flavored whey proteins are also quite delicious and can be used to add incredible flavor to healthy recipes like smoothies.
Whey is generally well tolerated, although people with lactose intolerance should be cautious, and some people may even be allergic to it.
