Combining different plant-based protein sources throughout the day ensures you get all nine essential amino acids. For instance, pairing an incomplete protein like lentils with a grain like rice forms a complete protein meal. Active individuals or those building muscle may need to consume higher quantities or more concentrated sources, but variety is key for everyone. For additional dietary information, consult reputable sources like Healthline on the best plant-based protein options.
