Animal-derived foods such as milk and its products, meat, fish, poultry and eggs play the most important role in the human diet, providing them with high levels of protein. Proteins not only provide the essential amino acids that make up our body’s cells. Rather, they are important in the case of central proteins and enzymes, as well as in the essential functions of life, such as reproduction, cell growth, maturation, cell differentiation, virus activity, and genetic activity.
Proteins are made up of amino acids, some of which are essential. According to preliminary studies, amino acids whose absence in the diet of experimental animals used in laboratories can hinder development or cause death are called essential amino acids.
The Dietary Classification Of Amino Acids Is Given Below.
- Essential Amino acids: histidine, lysine, tryptophan, phenyl alanine, methionine, threonine, leucine, isoleucine, androline.
- Semi Essential Amino acids: arginine, tyrosine, cysteine, glycine and serine.
- Non-Essential Amino acids: glutamic acid, aspartic acid, alanine, proline, and hydroxyproline.
- Of the semi-essential amino acids, arginine and gluten are essential for chickens. Tyrosine and cysteine are partial substitutes for phenyl alanine and methionine, respectively. Siren may be a partial or complete alternative to glycine.
Proteins can be grouped on the basis of whether they are derived from animals or from plants, thus they can be divided into two types of animal proteins and plant proteins. Essential amino acids in animal proteins are higher in quantity and number than in plant proteins.
Are present and their nutritional value is also high. The rate of growth in white mice is considered a measure of the nutritional value of protein. Over a period of time, rats with protein in their diet gain two to three times more weight than those that eat plant proteins.
Two Animal Proteins Are An Exception:
Collagen or gelatin and elastin, both of which are found in the synthetic cells of meat. Proteins are classified as complete and incomplete proteins based on modern knowledge of the biological differences between amino acids. Biologically complete proteins are those that contain all the essential amino acids we need.
We can add almost all animal proteins to the list of complete proteins. Incomplete proteins are deficient in one or more amino acids. This reduction can be absolute or relative. Most plant proteins are considered incomplete on this basis. Because some of these essential amino acids are missing.
Egg proteins are considered the standard for countering the nutritional value of various items. They are counteracted by the essential amino acids in eggs. Egg proteins are more digestible. In addition to the synthesis of essential amino acids, important factors in the nutritional value of proteins include the amino acids being free and the digestion of proteins. Numerous experiments have shown that animal proteins are more digestible than plant proteins. These foods, such as milk, meat and eggs, have a high potential for amino acids.
The Required Amount of Protein in Our Diet:
There is no doubt that human protein needs have been assessed based on the experiences of development and delivery in children and adolescents. The combination of plant and animal proteins can be used in the best way.
Certain plant proteins that are deficient in certain essential amino acids can also cause problems. Human needs can be met even with slightly less animal protein. It is a fact that animal proteins are superior to plant proteins in terms of nutritional value. Developed countries have higher levels of animal protein than developing countries and the economic condition of the people improves. The use of animal proteins in them is also increasing.
- People in developed countries
- Incorporate more animal proteins into your diet.
- Effects of protein deficiency
In many developing countries, food usually consists of grains and pulses. This includes very little food from animal sources. Animal foods are rarely available in these areas. The prices of animal proteins are much higher than the purchasing power of the people.
