Proteins are essential for the proper functioning of our body. From proteins are formed functional and structural components of our cells and body tissues, in addition to many chemical elements (hormones, enzymes and neurotransmitters) are provided by them.
What is a protein?
When we talk about protein we mean a macronutrient, that is, a substance that gives energy to the body, and other elements necessary to repair, build organic structures, and to promote growth and to regulate metabolic processes. Proteins are part of this group like Carbohydrates and fats.
Proteins are composed of chains of amino acids. There are 20 types and some of them our body cannot produce by itself, so it needs to incorporate them through food. These amino acids, which the body cannot synthesize on its own, are 8 and are called "essential amino acids".
Are there different types of proteins?
Yes. First, proteins can come from both animal origin as well as vegetable origin. On the other hand there are "different quality", a high-value protein is one that has all the amino acids that the body needs and cannot produce.
Since amino acids are the ones that regulate most of the vital functions of our body, maintaining a balanced diet is extremely important. If amino acids are ingested in the proper balance, the body will be able to use them effectively.
Why do we need protein?
Body composition is basically made up of water, lipids, and protein. We use protein to build and maintain:
- Hair, skin and nails
This is why they are so important!
