what is protein

The etymological origin of the word protein, a term created in the 19th century by the chemist Jöns Jacob Berzelius, is found in Greek. It derives exactly from the sum of "protos", which means "first", from the suffix -eios and from the suffix -ina, which is used to name chemicals. In this way, it is how said word was created, which comes to define a type of macronutrient that becomes fundamental when it comes to developing muscle mass .

Specifically, said development takes place when the aforementioned proteins are broken down, thus going on to 'nourish' the aforementioned muscle mass. A situation that, in addition, considerably favors what is the metabolism.

What are proteins made up of? Of amino acids, which come to be organic compounds of oxygen, nitrogen, carbon, sulfur and even hydrogen.

Likewise, it must be taken into account that macronutrients, among which are also fats and carbohydrates, also provide us with the daily energy we need.

Protein benefits What is it for?

As we have mentioned, what protein basically does is give us energy and, in the same way, contributes to the development of our muscle mass. But this is not all, because it should also be noted that eating foods rich in it helps us feel more satisfied and, therefore, to reduce our appetite.

In the same way, it must be taken into account that different studies carried out around these macronutrients that concern us, such as those published in PubMed.gov , have yielded really interesting data. Thus, for example, they have determined that those who eat foods rich in them have better cognitive performance and even a better state of mind.

It goes without saying that they are also considered to help keep the bones in good shape and contribute to recovery after having suffered some type of injury. Moreover, it is established that they play an essential role in the proper functioning of the endocrine and immune systems.

protein sources

Likewise, it is important to keep in mind that there are two types of food sources of protein:

  • Those with complete proteins , that is, those that provide the nine essential amino acids (methionine, threonine, histidine, valine, tryptophan, isoleucine, phenylalanine, lysine and leucine). In this food group are quinoa, chia seeds, meats and dairy products in addition to soybeans. What's more, we must not forget that there are supplements that also provide those, such as Energy 3 and Keto Sport .

  • Those with the incomplete proteins , which only have small amounts of them. These are legumes and cereals as well as nuts, for example. Hence, it is recommended to combine several of these foods in order to achieve a more 'perfect' diet in this regard.

All of them can be used when you want to enjoy an organism that is not deficient in terms of these macronutrients given their importance. However, as we have already indicated above, you can also choose to use their accessories that are for sale. The important thing is that the body has the necessary amounts of protein for its proper functioning.
