Information regarding plant-based nutrition focuses on the necessity of nine essential amino acids that the human body cannot produce internally. To ensure effective protein synthesis for muscles, enzymes, and hormones, a protein must be ‘complete’, containing all nine amino acids in sufficient proportions.

In plant-based diets, certain foods may contain ‘limiting amino acids’ that dictate the effectiveness of protein utilization. Common deficiencies include lysine in grains such as rice, wheat, and corn, as well as methionine in legumes like lentils, chickpeas, and black beans.
