Whey protein is one of the two milk proteins — the other is casein. It can be separated from milk via a series of procedures. It is also separated from milk during the cheese-making process. It is the watery by-product when milk curdles and becomes cheese.
Whey protein has all nine essential amino acids. It contains beta-lactoglobulin, bovine serum albumin, alpha-lactalbumin and immunoglobulins. These proteins are easily digested and absorbed by the body. They do not cause any irritation to the lining of the stomach and intestines. It has a low allergen profile, as compared to casein. It is low in lactose, which is responsible for triggering symptoms of milk allergies in some people.
Due to its low allergenic profile, whey protein is used as a milk and protein substitute. People with asthma, allergies (particularly milk and protein allergies), and lactose intolerance are given whey protein. It is used to improve the nutritional content of an otherwise nutritionally deficient diet in these conditions, due to the disease-related constraints.
Whey Protein Availability
This special protein is available in 3 main forms. Each form has different amounts of proteins. Basically, the more protein content, the less fat and sugar it contains.
Whey protein concentrate is close to the raw powder form. It has about 30 to 80% protein. Whey protein isolate is raw whey protein that has undergone further processing to remove more lactose (carbohydrates) and fats. It is considered as the purest form of whey protein. It contains at least 90% protein. Many consumers prefer to use the isolate as part of their weight lose regimen.
The third form is whey protein hydrolysate. This is the predigested form, which means it is the easiest to absorb for the body. This is the whey protein used for medical conditions. Due to its partially hydrolysed proteins, it does not require much digestion from the body. It is given as a protein supplement in cancer patients and those with other chronic conditions. It is also the form contained in infant formulas because it is least likely to cause allergic responses.
Benefits of Whey Protein
Amino acids for cellular health:
Essential amino acids in whey protein stimulate protein synthesis in the body. One particular amino acid used for this purpose is leucine. This process is especially important in speeding up the rate of recovery. More protein synthesis increases the body’s adaptation to stress, hence, strengthens the body’s fight against damage due to stress.
Cysteine is another amino acid in whey protein. It helps the body synthesize glutathione. This substance is important in defending the body cells against damage brought about by free radicals. Glutathione is a potent antioxidant that the body produces. Hence, some studies support the claim that milk ingestion reduces the risk of developing certain types of cancer.
Whey protein for repair:
Naturally occurring BCAAs (branched-chain amino acids) help to repair cells, muscle and bone tissues. High levels of BCAAs help to combat fatigue by providing a steady and abundant supply of amino acids for protein synthesis. The more proteins produced by the body, the faster and greater repair happens. Having an active lifestyle requires more BCAAs because the body needs to constantly build and repair muscle tissues. Whey protein is rich in BCAAs, making a great nutritional supplement.
Weight loss programs give better and faster results when whey protein is added to the diet plan. It has little fat and carbohydrates, and more proteins. It is ideal to be part of a meal replacement strategy.
Protein helps you to feel fuller and more satisfied with a meal. Hence, it lessens the amount of food you eat and the frequency by which you feel hungry and eat again.
It effectively curbs your hunger pangs, especially during the early stages of a diet program. The recommendation is to drink a glass of whey protein shake 20 minutes before a meal, preferably at breakfast and dinner. It can also boost the metabolic rate, helping you burn more fat at a much faster rate.
