Whey protein can contribute to muscle strength and development, help regulate body weight, and facilitate the control of conditions such as diabetes, high blood pressure, and inflammatory bowel disease, among a host of other health benefits. Proteins separated from whey are called whey proteins or whey protein.
1. Whey protein is one of the highest quality proteins
This protein is complete and of high quality, as it contains all essential amino acids. In addition, it is very easily digested and quickly absorbed compared to other types of protein. This is precisely why protein is one of the best food sources of protein. It is very popular among bodybuilders, athletes and anyone who wants to increase their protein intake.
There are three basic types of whey protein, classified according to the percentage of protein in the final product:
• Concentrate (WPC): up to 89 percent protein
• Isolate (WPI): 90 percent or more protein
• Hydrolyzate (WPH): variable proportion of protein.
Concentrate is the most widely available and usually the most affordable, while isolate has the highest percentage of protein and the fewest calories, but is generally more expensive.
2. How whey protein can promote muscle strength and repair
Protein is key to maintaining and building muscle mass, especially as we age. It supports cell regeneration and provides energy and material for tissue renewal.
Whey protein is rich in leucine, an amino acid that most strongly stimulates muscle growth.
Research shows that whey protein supplementation can play an important role in preventing and alleviating sarcopenia (loss of muscle mass due to aging). It can also contribute to increasing muscle mass and strengthening strength. However, strength exercises are a necessary part of training, and protein alone cannot replace training. The best results are achieved with a combination of strength training and a diet rich in protein, carbohydrates and healthy fats.
3. May help lower blood pressure
High blood pressure is one of the main risk factors for heart disease. Some studies have shown that whey protein can reduce systolic blood pressure, especially when more than 30 g of the isolate is taken daily for a period of about 10 weeks.
This effect may be related to the bioactive peptides in milk, especially lactokinins, which act as natural ACE inhibitors. More research is needed, but there is encouraging evidence, especially in people who are overweight and have mild hypertension.
4. Support for the regulation of type 2 diabetes
Type 2 diabetes is characterized by elevated blood sugar and impaired insulin function. Whey protein can help control diabetes by lowering postprandial blood sugar, increasing insulin levels and effectiveness, stabilizing glucose, increasing satiety, and lowering lipids such as triglycerides.
It is important to choose products with minimal added sugars and carbohydrates.
5. Possibility of reducing inflammation
Inflammation is the body’s natural response to damage, but chronic inflammation can contribute to the development of many diseases. Research shows that whey protein can reduce levels of CRP and IL-6, two key markers of inflammation in the body.
6. May Help Inflammatory Bowel Disease (IBD)
IBD diseases include Crohn’s disease and ulcerative colitis. Whey protein can contribute to remission and prevention of exacerbations by stimulating the secretion of mucin, a protective protein of the intestinal mucosa, reducing inflammation, improving intestinal barrier function and supporting the intestinal microbiota.
7. Strengthening the body’s antioxidant defenses
Antioxidants protect the body from oxidative stress, and whey protein can increase the level of glutathione, one of the most important antioxidants that the body produces. More human research is needed to confirm this effect.
8. Better blood fat levels
Elevated LDL cholesterol increases the risk of heart disease. The combination of exercise and whey protein can reduce LDL and total cholesterol, and in longer studies (12+ weeks) also lower triglyceride levels.
9. Less hunger and better regulation of body weight
Protein is generally the most satiating macronutrient. Whey protein personally enhances the secretion of satiety hormones, such as GLP-1, CCK and PYY. Some studies show that the effect is stronger than with casein or soy protein.
Increased protein intake is a well-known weight loss strategy. It helps because it increases satiety, reduces hunger and the desire for snacks, increases the thermic effect of food and preserves muscle mass during a caloric deficit. Whey protein has been shown to be particularly effective when combined with physical activity and a proper diet.
Possible side effects
Whey protein is generally safe in recommended doses, usually 25-50 g per day. However, excessive intake may cause mild gastrointestinal discomfort, such as bloating, cramping, gas, diarrhea, and abdominal discomfort.
Doctors warn that people with lactose intolerance tolerate isolate or hydrolyzate better, and if you have kidney or liver diseases, consult a health professional before starting supplementation. Such people can have more side effects as well as worsening of the symptoms of the underlying disease, doctors warn, and the cause is a reduced possibility of absorption.
