How do proteins affect our lives?
The human body is constantly updated. It is also constantly exposed to various external influences: it works, wears out, and as a result, it needs to recover, and for this, it needs nutritional elements. Our body consists of 220 billion cells and many of these cells are gradually updated throughout a person’s life.
To ensure that cells are updated in a timely manner and there are no interruptions in the organism functioning, proteins are necessary, since they are the main building element of any cell.
In our body proteins perform many functions:
- Catalytic – enzymes are made up of proteins, and they are responsible for speeding up chemical reactions that take place in the body.
- Structural – as we mentioned earlier, proteins are the main building blocks of cells. Proteins such as collagen and elastin are the main components of the intercellular substance of connective tissue (for example, cartilage). Another protein - keratin - is the component that makes up our hair and nails.
- The protective function of proteins can be divided into 3 types:
- Physical protection, which is possible thanks to the collagen, which is the basis of bones, tendons, cartilage and deep layers of skin. Also, the group of proteins responsible for the protective function includes keratin, which is the basis of hair, and fibrinogens and thrombins involved in the process of blood clotting.
- Chemical protection involves the binding of toxins with protein molecules and subsequent detoxification.
- Immune protection is also possible thanks to proteins. They are part of the blood and other biological fluids involved in the body's response to pathogens. Antibodies that are part of the adaptive immune system and neutralize substances foreign to the body are also proteins.
- Regulatory – many processes inside cells are regulated by protein molecules. This occurs due to enzymatic activity (see the catalytic function) or by binding protein molecules to other molecules.
- Transport–proteins are involved in the transfer of substances inside the cell, between cells, and in the transport of substances by blood or other fluids through the body. For example, the protein hemoglobin transfers oxygen from the lungs to tissues and organs.
Due to insufficient protein intake, these functions may be impaired. If you notice that you often have edema, you get sick, your skin, hair and nails are in the bad condition, you constantly feel tired - it may be that the whole thing is a lack of protein in your diet. To provide the body with all the necessary elements in a timely manner, it is important to ensure that the digestive system works correctly. Our Digestive Fortitude is created to support healthy digestion and promote gastrointestinal tract work properly.
The main sources of protein are meat, fish, seafood, eggs, legumes, nuts, and hard cheeses.
On average, a person needs 1.2-1.3 grams of protein per 1 kg of body weight. That is, if your weight is 60 kg, your daily protein intake will be somewhere between 72-78 grams per day. But if a person does sports, is ill, or senior, the need for protein will increase.
