Kind of. Most meals already have all the amino acids you need. Even if you were just eating plain rice. But just not as much from some types as others. In beans it would be the other way around.

If you are already regulating what you eat and praying a lot of attention to the nutritional value or the calorie count, it might make sense to use this hack to limit the amount of food you are eating.

But if not, you probably are already getting all the amino acids and proteins you need. Just not in the maximal efficient and compact way.
