In the 1970s, popular thinking was that vegetarians/vegans needed to be mindful of food combining (think rice and beans) in order to ensure each meal contained the full profile of amino acids. This concept was created by sociologist/activist Frances Moore Lappé, the author of Diet For a Small Planet. However, professionals have long known that the concept of food combining for the purpose of creating complete proteins is a myth. Even Frances Moore Lappé realized her mistake and retracted her statement, but unfortunately this misconception still lingers on. As long as you eat a varied diet with enough calories, you will supply your body with all of these building blocks; they do not have to be eaten in the same meal.
