The truth lies somewhere in the middle. It is easy to get enough protein on a vegan diet if you eat multiple servings of high-lysine foods (legumes, seitan, amaranth, quinoa, pistachios, and pumpkin seeds) each day. But there are many vegans who are probably not eating enough high-lysine foods.
Protein is built from building blocks called amino acids. Our bodies make amino acids in two different ways: Either from scratch, or by modifying others. A few amino acids (known as the essential amino acids) must come from food. 1  Animal sources of protein tend to deliver all the amino acids we need.  Other protein sources, such as fruits, vegetables, grains, nuts and seeds, lack one or more essential amino acids.
