Whey is the liquid remaining after milk has been curdled and strained. It is a byproduct of the manufacture of cheese or casein and has several commercial uses. Sweet whey is a byproduct resulting from the manufacture of rennet types of hard cheese, like cheddar or Swiss cheese. Acid whey (also known as sour whey) is a byproduct brought out during the making of acid types of dairy products, such as cottage cheese or strained yogurt. Whey proteins consist of α-lactalbumin, β-lactoglobulin, serum albumin, immunoglobulins, and protease peptones.[rx]

Whey serves as a foundational supplement and assists to achieve various goals for both women and men. It is easily digestible and required for building muscles and fat loss when combined with a healthy diet and exercise.
It is available in powder form also and is well known as a sports nutrition product due to its cost, availability, and effectiveness. Whey offers a wide range of amino acid L-cysteine that could alleviate deficiencies that occur during diabetes, aging, and other health problems. There are two types of whey: Acid Whey and Sweet Whey.
- Acid Whey
Whey results from cheese which adds an acid such as vinegar or lemon juice for the curdling process. Its types of cheeses are lemon cheese, mozzarella, and farmer’s cheese.
2. Sweet Whey
Whey is derived from that is cultured or curdled by not adding acid but with rennet. It could be drained from yogurt, clabbered raw milk, buttermilk, and milk kefir.
History
Whey is a liquid part of milk that remained after making cheese. It has been used for various health reasons for 24 centuries. In 446-337 BC, Hippocrates, a father of medicine prescribed whey to his patients. Another father of medicine named Galen in 131 BC-200BC, advised using whey to his patients. Then it is recommended to use as a substance to improve health in different regions of the world.
In 1794, a patient went to the Swiss mountain village of Gais as he could not be cured by the doctors. There he was provided whey regularly. An intake of whey helped to heal his health condition. The people gathered to Gais in order to get the benefit of whey protein. Soon, a health spa was opened in this village followed by 160 spas across Switzerland, Germany, and Austria. Throughout the 18th and 19th centuries, these spas were active in assisting emperors and aristocrats from across Europe.
Health spas of eighteenth-century engaged carefully timed system as the whey being a perishable beverage must be consumed within ten hours. The whey which has been prepared late at night was carried by remote mountain cheese makers to arrive before dawn to spas. Today, the fabrication of whey in the form of powder serves its benefits to everyone,
However, the whey available in the form of the package today is chemically treated and adulterated and lost its healing properties.

Health Benefits of Whey
The health benefits offered by whey are discussed below:
- Muscles health
Whey protein is a wise choice to add protein to the diet without adding extra calories from fats and carbohydrates. It contains from 80 percent to 90 percent protein that assists the body to build and strengthen muscles. Protein stimulates the synthesis of muscle to a greater degree than both soy protein and casein products. The addition of protein to the diet enhances gains in muscle mass. The results of the study showed an increase in total body mass, thigh mass, fat-free mass, and muscle strength.
- Helps to burn fat
The examination was made on the effect of whey protein without or with resistance exercise on body composition and body weight. The supplementation lowered body weight and body fat. Significant results were observed on those who combined supplementation of whey protein with resistance exercise.
- Lower cravings
Whey affects both leptin and ghrelin which are hormones that assist in regulating appetite. Leptin balances energy that suppresses food intake. Ghrelin assists in hunger regulation and has a role in the initiation of the meal. Studies have shown that the circulating levels of leptin are increased and ghrelin levels are decreased in obese patients. Whey helps to balance ghrelin and leptin secretion by lowering hunger cravings and preventing overeating.
Studies concluded that whey protein helps to lower caloric intake. An amino acid found in Whey protein is responsible for influencing satiety. Whey affects satiety and also intake of food which is mediated by the release of ghrelin and satiety promoting hormones. After the consumption of protein, hormones are released in the gastrointestinal system that suppresses food intake when supplementing with whey protein.
- Maintain a level of blood sugar
Whey stabilizes the level of blood sugar when consumed before meals with a high glycemic index. It promotes insulin production and also prevents spikes in blood sugar levels. Research shows that whey protein is also used for managing symptoms of diabetes. It slows down gastric emptying, promotes insulin and gut hormones such as incretin which releases after one consumes and assists to lower the level of blood glucose. Naturally, it could lower the level of blood sugar when eaten before a meal.
- Energy production
Whey protein promotes glycogen which is an energy source during heavy activity and exercise. It promotes the leptin effect which is a hormone affecting energy balance. Moreover, whey is digested easily and absorbed by the body. It is also converted into energy and assists to enhance energy levels naturally.
- Promotes Glutathione
Whey promotes glutathione production which is an antioxidant found in everybody’s cells. Glutathione scavenges free radicals which damage cells, cause aging-associated diseases such as Alzheimer’s, Parkinson’s, and also cancer. It prevents the body from drug resistance and environmental toxins.
- Strengthen immune system
Whey protein enhances glutathione synthesis and enhances the immune system. Glutathione promotes the efficacy of antioxidants such as CoQ10, vitamin C, ALA, and Vitamin E. It possesses various proteins and vitamins such as Vitamin D which has a positive effect on the immune system and acts as antimicrobial activity. Not only it promotes glutathione production but also it possesses L-lysine and L-arginine, amino acids which enhance immune function.
- Healthy heart
Studies have shown that whey enhances lowering blood pressure, arterial stiffness and promotes lipid profiles. It lowers cardiovascular risk factors by protecting muscle health and assists to lose weight. Low body weight reduces the problems related to obesity such as heart diseases.
- Long life
Whey promotes life span by lowering muscle wasting which is related with again and promoting absorption of nutrients without promoting hunger. As people age, one loses bone mass, digestive function and cell function also decreases. It also slows down the aging process. Study shows that supplements of whey protein caused positive effects on muscle protein synthesis, muscle strength, and muscle mass. It also improves muscle health; maintains weight, energy and supports cardiovascular function in elderly people.
