Busting the myth of the complete protein : TreeHugger

Some of our many vegetarian readers probably learned this long ago, but I will admit to remaining a sucker regarding the myth of the “complete protein.” So I am thinking maybe there are a lot of people with lingering fears of failing to combine the right vegetarian foods to make a “complete protein.”

My path to enlightenment started with the story of magician and entertainer Penn Jillette’s amazing weight loss. Success stories in dramatic weight loss maintenance are few and far between, so Jillette’s accomplishment perks my interest.

So I dug a bit deeper. First, one has to understand what we mean by “complete protein.” Proteins are made up of building blocks called amino acids. In order to grow…
