Plant proteins are proteins derived from various plants, including legumes, grains, nuts, and seeds. They are essential for building and repairing tissues in the body, just like animal proteins. Common sources of plant proteins include beans, lentils, quinoa, and tofu. These proteins are often lower in saturated fat and cholesterol compared to animal proteins. In addition to being nutritious, plant proteins can contribute to a balanced diet. They provide essential amino acids, though some may lack one or more of these amino acids. Combining different plant sources, such as rice and beans, can help ensure a complete amino acid profile for optimal health.
