Protein – what is it?

Proteins are macroelements that consist of amino acids and constitute the building blocks of our body. They are essential for the proper functioning of the body because they play many key roles, both structural and functional. Each protein is made up of different combinations of amino acids, which give them different characteristics and functions.

Protein – what is its role in the body?

The role of protein in the body is multifaceted. Firstly, they are the building blocks of muscle tissues, skin, bones, hair and other body structures. Secondly, proteins perform enzymatic functions, taking part in many metabolic processes. In addition, they transport nutrients, hormones and oxygen through the blood to various parts of the body. Proteins also participate in defense against infections, forming part of the immune system.

Vegetable protein and animal protein and their digestion and bioavailability

The difference between plant and animal protein is the source from which they are obtained. Animal proteins mainly come from meat, fish, eggs and dairy products, while plant proteins can be found in legumes, nuts, seeds and other plant foods. Protein digestion and bioavailability depend on its source and the structure of the amino acids it contains.

Protein requirements: in women, men and children

Protein needs vary depending on age, gender and level of physical activity. Adult men usually need more protein than women, and growing children have an increased need for this nutrient. Physically active people may also need more protein to support muscle recovery processes.

Excess and deficiency of protein in the diet – consequences

Too little protein intake can lead to amino acid deficiency and weaken the body. In turn, excess protein can burden the kidneys and cause various health problems. Therefore, it is important to maintain the right balance in your diet.

Products rich in protein – which one to choose?

If you want to increase your protein intake, it is worth reaching for products that are naturally rich in this ingredient. Such products include: chicken, turkey, fish, eggs, lean meat, tofu, nuts, seeds, peas, beans, and many others. By choosing a variety of protein sources, you can provide your body with various amino acids necessary for its proper functioning.

What should you pay attention to when choosing protein products?

When choosing products rich in protein, it is worth paying attention to their quality. Try to avoid processed products, which often contain additional preservatives and unhealthy substances. Choose protein sources that are low in fat and high in nutrients.

High-protein diets – when can they be recommended?

High-protein diets may be indicated in various situations, such as building muscle mass, reducing body weight, or for physically active people. However, it is always worth consulting a doctor or dietitian before starting such a diet to ensure its safety and appropriate adaptation to individual needs.

Animal protein vs. plant protein – which one is better? protein from the perspective of a dietitian

It is worth noting that both animal and plant proteins have their advantages and disadvantages. Animal protein is richer in several key amino acids, but may also be higher in fat and cholesterol. Plant protein is usually lower in calories and fat, but may require more intake to provide adequate protein. Therefore, it is worth including both types of protein in your diet to obtain a complete source of amino acids.
