Moon says a myth she hears a lot is that plant proteins are missing amino acids. "That's factually incorrect. There are no missing amino acids," she says. "Plant protein has all the same amino acids as animal protein – all 20, both essential and non-essential. The levels of specific amino acids may vary across plant foods given the diversity of plant foods, but again, getting protein from a variety of plant foods throughout the day will meet all amino acid needs, as long as you're eating enough overall. And if there are smaller amounts of animal proteins eaten, this is even less of a concern." So mix it up, and eat a wide range of plant-based foods.
