The foodstuffs listed for comparison show the essential amino acid content per unit of the total protein of the food, 100g of spinach, for example, only contains 2.9g of protein (6% Daily Value), and of that protein 1.36% is tryptophan.

What the latest science says about the difference between "complete" and "incomplete" forms of the nutrient.
Protein combining or protein complementing is a dietary theory for protein nutrition that purports to optimize the biological value of protein intake. According to the theory, individual vegetarian and vegan foods may provide an insufficient amount of some essential amino acids, making protein combining with multiple complementary foods necessary to obtain a meal with "complete protein".
In order to efficiently process amino acids two things need to be considered, the ability to process proteins and the ability to properly digest proteins in the food. [4] Protein or amino acids can be found in both plant products and animal products. However, each food type will have a unique amino acid and how they react or interact.
Egg white protein is a complete protein, and it has a higher net protein utilization rate (how much protein the body can use) than whey and soy proteins. It might be better for building muscle ...
Myth #1: An incomplete protein doesn’t count toward your protein goals It’s true that not all protein is created equal. According to the Cleveland Clinic, a “complete protein” contains all ...
A complete protein source contains all the essential amino acids; an incomplete protein source lacks one or more of the essential amino acids. It is possible with protein combinations of two incomplete protein sources (e.g., rice and beans) to make a complete protein source, and characteristic combinations are the basis of distinct cultural ...
Natural protein concentrates (often used in bodybuilding or as sports dietary supplements): Soy protein isolate (prepared with sodium or potassium): 80.66; Whey protein isolate: 79; Egg white, dried: 81.1; Spirulina alga, dried: 57.45 (more often quoted as 55 to 77) Baker's yeast: 38.33; Hemp husks 30
