Protein - The importance of this nutrient for our body.

Protein is a nutrient found in foods such as meat, fish, eggs, dairy products and also in plant foods such as soybeans, beans, peanuts, sesame seeds and lentils.
Proteins are fundamental macromolecules for the human body and perform several vital functions.
Here are some of the main reasons why proteins are important:
Tissue Building and Repair: Proteins are the building blocks of the body's tissues, including muscles, bones, skin and hair. They play a crucial role in the synthesis, maintenance and increase of muscle mass, because to build muscles, in addition to regular physical activity, it is necessary to consume adequate and good quality proteins, such as those found in real foods of animal origin, such as beef. , chicken and eggs.
Enzyme Function: Many enzymes, which are specialized proteins, act as catalysts in chemical reactions in the body. These reactions are essential for metabolic processes, such as food digestion and energy production. Stomach juices and digestive enzymes are made up of proteins, responsible for breaking down food into smaller particles for absorption by the intestine.
Transport of Substances: Proteins, such as hemoglobin, are responsible for transporting essential substances, such as oxygen, in the blood, so low consumption of this nutrient can cause problems such as anemia, weakness, paleness and lack of energy.
Immune System: Antibodies, which are proteins of the immune system, play a crucial role in defending the body against invaders such as bacteria, viruses and other pathogens. Without an adequate supply of this nutrient, the immune system is weakened and the body becomes more susceptible to diseases and infections.
Hormonal Regulation: Some proteins act as hormones, which play a crucial role in regulating physiological processes such as growth, development and metabolism. Hormones are also substances in the body made up of proteins, therefore, to have a good hormonal balance it is necessary to fully consume this nutrient. Problems such as polycystic ovary syndrome, stress or anxiety can be caused by hormonal changes and a balanced diet is essential to improve symptoms.
Maintain a good nervous system: Neurotransmitters such as adrenaline and acetylcholine are made of proteins and are responsible for transmitting nerve impulses that create thoughts, emotions and commands that cause the entire body to move and function properly.
Source of Energy: Although proteins are not the primary source of energy for the body, in situations of need, such as during hunger or intense physical activity, proteins can be used as a building block for the body's energy production and regulation. blood sugar, especially on low-carb diets.
Healthy joints: Joints are made up of tendons and have high levels of collagen, which acts as a shock absorber between bones, preventing wear and pain. Thus, as collagen is made from proteins, it is also important for maintaining good joint health and preventing injuries caused by exercise, which stresses the joints.
