Proteins are responsible for the growth and repair of the body’s tissues. They also play an essential role in the production of hormones, enzymes, and red blood cells.
Each protein is made up of smaller building blocks called amino acids. Because the body cannot store amino acids, it must get a regular supply from the diet.
In the United States, people get most of their protein from animal sources, such as meat, fish, and eggs.
People following a vegan diet must, therefore, ensure that they eat enough plant-based protein to meet their dietary requirements.
The U.S. Department of Agriculture provide an online calculator that can estimate a person’s recommended daily intake of protein and other nutrients.
