Proteins are complex compounds consisting of hundreds or thousands of smaller units called amino acids, linked together in long chains to form a protein. There are 20 amino acids that make up different proteins, and they differ according to the arrangement of these amino acids, as their arrangement It is what determines the three-dimensional shape of the protein, which determines its functions, and it is worth noting that proteins play important roles in the body, as they are responsible for most cell functions, and are important for building the body, the functions of organ tissues and regulating their work.

Plant proteins are incomplete proteins that lack one or more of the essential amino acids, and most plant foods are a source of incomplete protein. It is worth noting that the essential amino acids that are not sufficiently available in plant sources are: methionine ; As its quantities in legumes are considered low, and lysine (in English: Lysine); Where its quantities in grains and seeds are low, and tryptophan (in English: Tryptophan), and it is worth noting that the low consumption of these amino acids is associated with low levels of protein production in the body, according to a study conducted at the Slovak Medical University in 2005, Which was conducted with the aim of knowing the benefits and caveats associated with vegetable proteins.

Amino acids are divided into two types, namely: non-essential amino acids that the body manufactures itself, and essential amino acids that the body cannot manufacture, as it must be obtained from food sources, and the body needs all amino acids to maintain its health, and it is worth noting that the foods that They contain animal protein and are often rich in many other nutrients, such as: vitamin B12, vitamin D, docosahexaenoic acid (DHA), heme-iron, and zinc.

There are three types of protein in food, the first is the complete protein, which includes foods that contain all the essential amino acids, and they are available in animal sources such as meat, eggs, and cow’s milk, and the second type is the incomplete protein, and it includes foods that contain one type At least of the essential amino acids, including: peas, beans, whole grains, and finally complementary proteins, which consist of two or more types of foods that contain incomplete proteins, which must be eaten together to obtain complete protein, including: bread with peanut butter Peanuts, or rice with beans.
