Your body can produce many amino acids on its own, but some essential ones must come from your diet. To this effect, supplements can be of great help in case you are not getting enough protein from food. One of the easiest ways to ensure you get these vital nutrients is by consuming whey protein, a complete protein, which has all the nine essential amino acids required for bodily functions including building muscles and immune cells.
What is whey protein?
In simple terms, whey protein is the liquid part of milk that separates from the curds during cheese-making or while manufacturing casein. This by-product, liquid whey, is pasteurized to kill bacteria and then dried to create powder supplements. It contains a mixture of eight proteins: beta-lactoglobulin, alpha-lactalbumin, glycomacropeptide, immunoglobulins, bovine serum albumin, lactoferrin, lactoperoxidase, and lysozyme.
Types of whey protein supplements:
There are three main types of whey protein supplements based on the processing technique and the nutrient content:
Whey Protein Concentrate (WPC)- When water, lactose, and minerals are removed from whey to boost its protein concentration to 25% or more, it transforms into whey protein concentrate. This concentrated form is manufactured through processes like precipitation, filtration, or dialysis, refining the whey into a powerful protein source packed with essential nutrients.
Whey protein concentrate can be produced in various concentrations to meet different requirements. For example, WPC35 contains 35% protein, while WPC80 has a higher concentration of 80% protein, allowing you to choose the right level of protein based on your goals.
Whey Protein Isolate (WPI)- Whey protein isolates are a highly concentrated type of whey protein, with 90% protein and only 4–5.5% water. They are crafted using advanced techniques like ion exchange chromatography. Due to their high protein content, isolates are used in sports drinks and protein-fortified beverages. They also function as water-binding, gelling, emulsifying, and foaming agents.
Whey Protein Hydrolysate (WPH)- Whey protein hydrolysate is the purest form of whey protein, created by breaking down whey protein concentrate or isolate using heat, acids, or enzymes. This process transforms it into an easily absorbable protein that is gentle on the digestive system.
Benefits of whey protein
Traditionally, whey has been used for several medicinal purposes, including for soothing burns, as an aphrodisiac, and skin balm. Most recent research points to the use of the supplement for various purposes, including muscle strengthening and weight loss.
1. Muscle strength- For those considering building lean muscle or for those trying to revive lost muscle strength due to aging, whey protein is considered a good option. A 2017 study published in the journal Nutrients revealed that whey protein supplements could be a game-changer for resistance-trained individuals. According to the study, taking whey protein after a workout not only helps reduce overnight muscle loss but also enhances recovery.
2. Weight loss- Research suggests that whey protein is a low-cost and readily available nutritional supplement that can be easily integrated into a weight loss intervention. It is also found to be a beneficial dietary supplement to enhance fat loss, while sparing lean muscle in obese individuals.
3. Boost immunity- A study published in the journal Foods indicates that whey protein supplements could improve the production of antibodies and resistance to bacterial infections. Research also suggests that whey protein supplements could strengthen the body's defenses by promoting the formation of glutathione, one of the body's main antioxidants.
4. Manage diabetes- Whey protein has potential in the dietary management of diabetes as studies show that if taken a few minutes before meals, it can slow down digestion, boost insulin and gut hormones, improve satiety, and lower blood sugar levels after meals.
5. Reduce cholesterol levels- The use of whey protein is found to improve total cholesterol, low-density lipoprotein, and blood pressure. Research has shown that whey protein supplementation can benefit overweight adults by improving their body composition, lipids, insulin, and glucose levels.
6. Reduce heart disease risk- Since high cholesterol and blood pressure are risk factors for heart disease, a supplement that could reduce them both would improve heart health.
Possible risks of whey protein
For most people, whey protein supplements are safe to use. However, it is not recommended for those with a dairy allergy. Ingesting large quantities of whey protein can cause side effects such as constipation, diarrhea, or nausea. Taking too much whey protein or taking supplements with added sugars, and sweeteners can increase the total calorie intake and may result in weight gain.
