What Is Whey?

Whey protein can be defined as a combination of proteins that are extracted from whey. Whey is the liquid part of milk that is separated during the production of cheese.

There are two major types of protein that are found in milk; they are; casein which is 80% and whey 20%. Whey is present in the liquid portion of the milk coagulate and the whey is obtained from it as a byproduct (R).

Have you ever noticed for once that when you open a yogurt container, there is a liquid substance that floats at the top, this liquid is known as whey.

Makers of cheese usually dispose of it before they identify its great commercial importance (R).

After it has been separated during the production of cheese, the whey is subjected to various processing steps before its metamorphosis into what people know as whey protein.

This is a powder added to shakes, meal replacements, and protein bars (R).

Ordinarily, whey protein does not taste good on its own, as a result of this, it must be flavored. Chocolate, vanilla, and strawberry-flavored powder are well-known.

Care must be taken to ensure safety as some of these products can contain unhealthy additives such as refined sugar.

One of the best ways to supplement about 25-50 grams of protein to your daily intake is by taking whey protein.

This has been found to be of great importance to bodybuilders and sports enthusiasts, and also for people that need to lose weight or those who are deficient in protein in their diet.

A lot of flavored whey proteins are also very delicious and serve as a way to supplement the unbelievable taste of healthy recipes such as smoothies.

Wheat is generally well accepted, but individuals with lactose intolerance should be careful and some people may be allergic to it (R).

Types Of Whey Proteinwhey isolate powder

There are many types of whey protein; the difference that exists between them depends on the way they are processed during production;

Below are the three major types of whey protein:

1. Concentrate: This type of whey protein contains approximately 70 to 80% of protein; it has some lactose (dairy sugar) and contains fat that has the best flavor.

2. Isolate: Isolate contains 90% protein or more; the lactose and fat content are low and there are not many useful nutrients contained in the whey protein concentrate.

3. Hydrolysate: This can also be referred to as hydrolyzed whey; this species has been predigested to hasten its absorption. It results in a 28 to 43% increase in the level of insulin (R).

Whey protein concentrate seems to be the best option.

It is cheaper and it retains most of the useful nutrients naturally present in whey. A lot of people also favor the taste, which is because of the presence of lactose and fat.

In the event that you have difficulties coping with concentrate, or you are trying to place emphasis on protein when keeping a low level of carbohydrates and fats, whey protein isolate or even hydrolysate may be a better choice.

Note that despite the fact that concentrate is the most famous form; a lot of research has been carried out on whey protein isolate.

Why Use Whey

It is known that proteins can help in weight loss because it is by far the highest quality macronutrient (R).

Proteins can increase energy consumption by 80 to 100 calories a day and encourage people to automatically consume up to 441 calories per day (R, R).

According to a study, it was revealed that consuming 25% of daily calories as a protein cut short cravings by 60% and reduced the desire for late enjoyment by half (R).

Taking whey protein has been attributed as one of the great ways to spike your consumption of protein, which should have great benefits for weight loss.

Research has shown that the replacement of other calorie sources with whey protein in combination with bodybuilding can result in a weight loss of about 3.5 kg with muscle mass increase (R).

On the off chance that you are trying to lose weight, whey protein supplements can help you lose weight and maintain muscles (R, R).

  1. You note that people who are allergic to milk may be allergic to whey. I’m lactose intolerant, so is there any way for me to know if I would be allergic to whey before I go out and purchase a big canister or protein powder?

    • Hi, the best thing to do if you are lactose intolerant is to check with your doctor before purchasing any whey products. However, there are whey products that are specifically “lactose free”. Total Activation makes a few whey products that are lactose free and low cholesterol.
