What are essential amino acids?

They help our body grow, repair body tissues, keep the brain active and provide energy... Yes, we are talking about essential amino acids and why they are so important for the body.Amino acids are organic compounds that combine to form proteins, supporting digestion, improving emotional health, helping calcium absorption and helping prevent certain diseases.

Essential amino acids

Essential amino acids are those the body cannot synthesise by itself, but which we need for the body to function properly. So where can we get them? From foods such as eggs, wheat, milk, cheese, red meat, pulses, broccoli, carrots and courgettes. The essential amino acids these foods should include are leucine, methionine, valine, threonine, histidine, lysine, isoleucine, phenylalanine and tryptophan.

One example is egg, considered a protein of high biological value because it contains all essential amino acids. It also contains them in a considerable amount, making absorption in the intestine easier and contributing to the proper functioning of the body. However, there are also foods that contain all essential amino acids, but one of them in a very small amount, or not at all. What happens then? It is considered a limiting amino acid, but that does not mean it is not beneficial for our body.

Why are essential amino acids necessary for the body?

Consuming essential amino acids every day, even in small amounts, is fundamental for the body and its proper functioning. That is why it is important to follow a varied diet that includes all the foods mentioned above and provides the necessary content of these amino acids. And what about vegetarians and vegans? Those who follow a lifestyle that does not include foods of animal origin should consult their nutritionist and follow a routine that ensures adequate intake.

Deficiency of these amino acids in the body

Low intake or lack of these amino acids can cause symptoms in the nervous system, as well as throughout the body and its systems, the locomotor system and muscle-level injuries. Another effect of this deficiency can be seen in wounds and their difficulty healing, in muscle recovery and even in changes to macronutrient metabolism. That is why it is so important to follow a balanced, healthy diet, exercise and consult a specialist if you notice symptoms that may indicate a lack of these essential amino acids.
