What is protein?
Protein is a nutrient your body needs to grow, repair and function properly. Protein is found in a wide range of foods and it is important that you get enough protein in your diet every day. The amount of protein you need in your diet varies depending on your weight, gender, age, health and activity.
Proteins are made up of amino acids:
There are about 20 different amino acids that are linked together in different groups. Your body uses them to make new proteins, such as muscle and bone, and other compounds such as enzymes and hormones. It can also be used as a source of energy.
What are amino acids made of?
Each amino acid consists of an amino group and a carboxyl group. These acids are involved in the formation of proteins, whether animal or vegetable. Most proteins found in food, with the exception of gelatin, are characterized by the presence of a certain percentage of each of these acids. .
There are some foods that contain essential amino acids:
They contain animal products (such as chicken, beef, fish, and dairy products) and are called “complete proteins” because they are of animal origin.
It contains soy products, quinoa, seeds of green leaves, and legumes such as (beans, lentils, beans, nuts, and whole grains). It is more suitable for vegetarians. They are called “incomplete proteins” because they are of plant origin and have little nutritional value compared to “complete proteins.” Animal origin
People who follow a strict vegetarian or vegan diet need to choose a variety of protein sources from a range of plant foods every day to ensure they get the right mix of essential amino acids.
If you follow a vegetarian diet, you can usually get the protein you need from incomplete protein. For example, a meal containing grains and legumes, such as baked beans on whole-grain toast, provides all the essential amino acids found in a typical meat dish.
There are people who suffer from anemia, and not every “anaemia” means a lack of blood, but there is protein anemia (protein deficiency), but it is not very common in the Arab world. Protein deficiency means not getting enough protein in your diet.
People most susceptible to protein deficiency anemia:
- the elderly.
- People who follow a strict vegetarian diet.
Symptoms of protein deficiency include:
- Wasting and shrinkage of muscle tissue.
- Edema (a buildup of fluid, especially in the feet and ankles)
- Anemia (inability of blood to deliver adequate oxygen to cells, usually caused by a deficiency in the diet such as iron deficiency).
- Slow growth (in children).
- Wounds do not heal quickly.
