What is whey protein?
Whey is a naturally occurring protein formed during the cheese-making process that is low in fat and carbohydrate and high in nutritional value. Whey contains all nine essential amino acids obtained through diet and needed by the human body, and can be dried to create a powder that can be easily added to meals as a nutritional supplement.
But there’s much more to know about whey protein. We have put together 15 most frequently asked questions and their answers to give you better insights into this unique superfood:
Whey originates from milk. When you produce cheese from milk, you get two things: cheese and whey.
Whey protein in its purest concentrated form contains little to no fat or lactose, and is a very rich source of protein and amino acids, which are needed daily by the human body.
Whey proteins are of very high nutritional quality and represent a valuable ingredient to include in human diets.
The building blocks of proteins are the so-called amino acids. 9 of the 20 amino acids that the body requires must be provided through diet – these are called essential amino acids.
Whey protein has a unique and a highly nutritional amino acid profile as it contains all the essential amino acids in the right proportion needed.
Whey protein is used in various kinds of processed foods – primarily in fresh dairy products, cheese, sport nutrition beverages and protein bars.
If a food product contains whey protein, it is declared on the ingredients list. Whey protein is also widely used in infant formula and medical nutrition.

In addition, whey protein helps restore body tissue and muscle and is easily absorbed by the human bod
In general terms, an amino acid profile refers to the content and distribution of the different amino acids found in a protein.
Whey protein is not a single protein but rather a mixture of proteins derived from whey. The exact profile of the amino acids found in a whey protein product depends on the processing of the whey raw material.

In general, an even distribution of protein during the day is recommended to provide a steady supply of protein and amino acids.
No, the composition and quality of proteins depend on the type and quality of the raw material used.
Typically, animal-derived protein contains the right proportions of the essential amino acids needed by humans.
Very often proteins that originate from plants do not contain the right proportions or sometimes even lack certain essential amino acids needed in human diets. The correct combination and often larger amounts of different plant protein sources are thus needed to fulfill daily needs .
Whey protein is a great source of high-quality protein for vegetarians, flexitarians, and people looking for cutting down their meat intake.
Studies show that most people can tolerate 5g of lactose per single dose, which should make whey protein products suitable for most people. However, the degree of lactose tolerance differs from person to person.
If you are unsure about your lactose tolerance, your doctor can determine your threshold level.
Whey protein is considered a safe food protein to ingest for all people, unless specific milk protein allergies exist.
Ingestion of whey protein as supplement can help people meet their daily protein needs and is both nutritionally efficient and easy to absorb.
