Proteins are fundamental molecules for the human organism, fulfilling a wide variety of vital functions ranging from the maintenance and repair of tissues to the synthesis of enzymes and hormones. Within the classification of proteins, proteins of high biological value are distinguished, which are of great importance for the health and proper functioning of the human body. In this article, we will explore in detail what proteins of high biological value are, their characteristics and the main food sources of them.
What are proteins of high biological value?
Proteins of high biological value, also known as complete proteins, are those that contain all the essential amino acids in the appropriate proportions that the body needs to carry out its functions optimally . Essential amino acids are those that the body cannot synthesize on its own and must be obtained through food.
Proteins are made up of chains of amino acids, and there are 20 different amino acids that can be combined in various ways. ways to create a wide variety of proteins with specific functions. When a protein is considered of high biological value, it means that it contains all the essential amino acids in adequate quantities to meet the needs of the human body.
Characteristics of proteins of high biological value
Some of the key characteristics of high biological value proteins include:
- They contain all the essential amino acids: High biological value proteins provide all the essential amino acids in the appropriate proportions for the human body.
- Digestibility: They are easily digested and absorbed by the body, which allows rapid availability of amino acids for bodily functions.
- Complete amino acid profile: They have a complete amino acid profile, which makes them ideal for protein synthesis in the body and for maintaining muscle mass.
Sources of proteins of high biological value
To guarantee an adequate intake of proteins of high biological value in the diet, it is important to include foods that are rich in this type of protein. Below are some food sources of proteins of high biological value:
1. Meats and poultry
Meats and poultry are excellent sources of complete proteins. Beef, chicken, turkey, pork and lamb are examples of foods rich in proteins of high biological value. These animal sources usually contain all the essential amino acids in the right proportions, making them an important part of a balanced diet.
2. Fish and shellfish
Fish and shellfish are another excellent source of proteins of high biological value. Fish such as salmon, tuna, trout and cod, as well as shellfish such as shrimp, prawns and mussels, provide a wide variety of nutrients, including complete proteins that help maintain health and well-being.
3. Eggs
Eggs are considered one of the most complete proteins of animal origin, since they contain all the essential amino acids in adequate quantities. In addition, they are an important source of other nutrients such as vitamin D and iron. Eating eggs regularly can be beneficial for health and nutrition.
4. Dairy products
Dairy products such as milk, yogurt and cheese are excellent sources of proteins of high biological value, as they contain all the essential amino acids. In addition, they provide calcium and other important nutrients for bone health and general well-being. Including dairy products in the daily diet can help meet protein needs.
5. Vegetable proteins
Although proteins of animal origin are considered proteins of high biological value, it is also possible to find proteins of vegetable origin that contain all the essential amino acids. Some plant sources of complete proteins include quinoa, soy, amaranth, and hemp. Combining different sources of plant proteins throughout the day can help ensure adequate intake of essential amino acids.
Conclusion
Proteins of high biological value are essential for the proper functioning of the body. organism, since they provide the essential amino acids necessary to carry out multiple physiological processes. Including complete protein sources in the daily diet is essential for maintaining health and well-being throughout life. By choosing foods rich in proteins of high biological value, you can ensure adequate intake of essential nutrients for the human body.
In summary, know what proteins of high biological value are, their characteristics and the main food sources of them is essential for a balanced and healthy diet. By incorporating complete protein sources into your diet, you can contribute to the maintenance of muscle mass, bone health, and the proper functioning of multiple body systems.
