Dear Doctors: What does it mean when something is a “complete protein”? A friend said that when I count beans or grains as a protein, it’s not the same nutritional value as meat or cheese. Are there really different kinds of protein? Is he right that it matters which kind of protein you eat?

Dear Reader: Proteins are vital to the health and function of our bodies. That makes it important to understand what they are and how they fit into the diet.
