Do proteins need to be combined in a vegan diet?
In its 1997 position paper on vegetarian diets, The American Dietetic Association stated that because amino acids from food combine with amino acids made in the human body, it is not necessary to combine proteins at every meal or even every day. If you eat a varied vegan diet containing nuts, vegetables, seeds, legumes, and grains, you will get adequate protein and the necessary amino acids.
