The traditional Western diet contains twice the protein required by the human body. Some experts argue that problems such as overactive immune system, liver dysfunction or bone loss may be related to an excess of protein.
Excessive intake of protein can also cause calcium loss, which can affect the health of the skeletal system.
Contrary to the recommendations made by the meat industry, only 10% of the daily food intake should come from protein. In the West, most protein comes from animal sources, which increases the amount of fat absorbed.
In addition to being an important nutrient, protein is necessary for the development, maintenance and repair of body tissues. Amino acids are in turn essential for the production of proteins.
A wide variety of vegetables, grains and alternatives can provide all the amino acids our bodies need. The main sources of protein include eggs, soy, grains, vegetables and dairy products such as yogurt.
Previously, it was believed that a specific combination of vegetables and grains should be consumed simultaneously to achieve a complete protein intake in a vegetarian diet. This theory is known as the ‘combination of proteins’ or ‘protein supplement’ theory. It was recently discovered that simultaneous combination is not necessary to obtain all the essential amino acids. If the diet contains a variety of grains, legumes and greens, the protein needs of the body will be met.
