The role of protein in human health

Protein, also known as proteins, is the basic building block of every cell in the body. It consists of amino acids, which are essential for tissue repair, enzyme production and hormones. The human body is unable to store protein ‘for longer’, which means that we must regularly supply it in adequate amounts through food.

Protein supports cell and tissue regeneration and plays a key role in the functioning of the immune system, transports nutrients, and supports the production of hormones and enzymes that regulate metabolic processes. It is essential for the health of the skin, hair, nails, bones and muscles.

Protein in the diet of athletes

For athletes, both amateur and professional, adequate protein intake is absolutely crucial. Protein acts as the ‘building blocks’ for muscle growth, which is particularly important in strength and bodybuilding sports. Protein also aids post-workout recovery, which is essential for maintaining high performance and avoiding overtraining.

Protein in strength and bodybuilding sports

In strength and bodybuilding sports, such as bodybuilding, powerlifting and CrossFit, an adequate protein supply is crucial for building muscle mass. After intense strength training, microdamage occurs in the muscles, which must be repaired. Protein is the nutrient that enables muscle regeneration and growth. In these sports, it is most often recommended to consume 1,6 to even 2,3 grams of protein per kilogram of body weight per day.

Protein in other sports

Although protein is mainly associated with strength sports, its role in other sports, such as running, swimming and cycling, is equally important. Endurance athletes who train intensively also need adequate amounts of protein for recovery and maintenance of muscle mass. During prolonged physical exertion, the body may begin to use protein as an energy source, which further emphasises the need for a regular supply of this nutrient.

The role of protein in weight loss

Protein plays a key role in the weight loss process. Thanks to its properties, it helps control appetite and prolongs the feeling of satiety after a meal. Protein consumption supports the process of thermogenesis, which means that the body uses more energy to digest and metabolise protein than it does carbohydrates or fats. In addition, protein helps to protect muscle mass during a calorie deficit, which is extremely important for people who want to reduce body fat but at the same time maintain their physique.

A high-protein diet is one of the most effective ways to maintain and increase muscle mass while losing weight. Combined with strength training, an adequate protein intake can contribute to better results in reducing body fat while maintaining muscle.

Protein in sports supplementation

Modern protein supplements, such as protein powders, are a great solution for people who want to get the right amount of protein quickly and conveniently. Protein supplementation is particularly popular among athletes, but it can also be used by people who have difficulty getting enough protein from their diet.

When is the best time to use a protein supplement?

The optimal time to consume a protein supplement depends on your training goals and meal schedule throughout the day, but it is most often recommended to take it immediately after training. At this time, the body is particularly receptive to the amino acids provided, which promotes faster regeneration and stimulates the process of muscle fibre repair.

On non-training days, the supplement can be used as a convenient addition to our meals in situations where it is difficult to obtain the right amount of protein from food. Regular use of a protein supplement helps to maintain a stable protein supply, which is crucial for both those building muscle mass and those on a reduction diet. The most important thing is to ensure that your daily diet contains a sufficiently high amount of protein that is tailored to your goals.

The most popular forms of protein supplements are:

• Whey protein isolate (WPI) – an excellent choice for people on a weight-loss diet and athletes.
• Whey protein concentrate (WPC) – a versatile protein with high biological value.
• Plant protein – ideal for vegans and people with lactose intolerance.
• Casein – the perfect protein for the night, supporting muscle regeneration over a long period of time.

Protein supplements make it easy to control the amount of protein you consume, which is extremely useful, especially for people who do strength training or intense exercise.

Protein and safety

Consuming protein, both from natural sources and in the form of supplements, is safe and beneficial to health, as long as the recommended doses are followed. However, it is important to remember that excessive amounts of protein can put strain on the kidneys, especially in people with pre-existing health problems. Therefore, people with kidney disease should consult their doctor before introducing protein supplementation and should not exceed the amounts recommended by the manufacturer.

Scientific studies show, however, that in healthy individuals who do not have kidney problems, even higher protein intake does not pose a health risk. Regular protein consumption supports bone, muscle, skin and immune system health.

Protein supplements in the diet of seniors – why are they beneficial?

With age, the demand for protein increases because it helps maintain muscle mass, which naturally decreases with the ageing process. Protein supplements are an excellent way to supplement the diet of grandparents with easily digestible protein, especially when their appetite is reduced or their diet is monotonous. It supports muscle regeneration, strengthens bones and improves overall vitality. Whey or plant proteins in the form of shakes are convenient and tasty, and thanks to a variety of flavours, they can be easily tailored to the preferences of seniors, helping them stay healthy and in good shape for longer.

What do trainers and dieticians say about protein supplements?
