The transition toward plant-based (PB) diets has gained attention as a plausible step toward achieving sustainable and healthy dietary goals. However, the complete elimination of all animal-sourced foods from the diet (ie, a vegan diet) may have nutritional ramifications that warrant close examination. Two such concerns are the adequacy and bioavailability of amino acids (AAs) from plant-sourced foods and the consequences for older vegan populations who have elevated AA requirements.

- A plant-based diet can be healthy, but overly restrictive diets may lead to nutrient deficiencies, particularly in protein quality and amino acid digestibility.
- This review examines 23 studies that modeled protein intake and quality when substituting animal proteins with plant-based options, focusing on different age groups' dietary needs.
- Results showed that while plant-based options can meet some nutritional requirements, they often fall short for children and older adults, particularly when not using high-quality sources like legumes, nuts, and seeds.
