Is your meal a complete protein?

Free, no sign-up, nothing uploaded. Mix the foods on your plate — rice and lentils, oats and milk, beans and corn — and see whether together they supply all nine essential amino acids, which one is holding the mix back, and exactly what to add to complete it.

Frequently asked questions

What is a complete protein?
A protein that supplies all nine essential amino acids — histidine, isoleucine, leucine, lysine, methionine (+cysteine), phenylalanine (+tyrosine), threonine, tryptophan and valine — in at least the proportions the body needs. Eggs, dairy, meat, fish, soy and quinoa are complete on their own; most grains, nuts and many legumes are not.
How can two incomplete proteins make a complete one?
Different foods run short of different amino acids. Grains like rice and wheat are usually low in lysine, while lentils and beans are rich in lysine but lower in methionine. Eaten together, each fills the other's gap — which is why dal and rice, hummus and pita, or beans and corn tortillas are traditional pairings.
How is the score calculated?
The tool pools the amino acids from every food in your mix, divides by the mix's total protein, and compares each essential amino acid to the FAO/WHO (2007) adult reference pattern in mg per g of protein. The lowest ratio is the amino acid score; if it's 100% or more, the mix is complete. Data comes from USDA FoodData Central.
Do I need to eat complementary proteins in the same meal?
No — current nutrition science says your body pools amino acids over the day, so the foods don't have to be on the same plate. Checking a whole day's foods together is just as valid as checking one meal.
Why isn't a food I searched for available?
Only foods with a full amino-acid profile in the USDA database can be scored — about 5,000 of them. Prepared dishes and some branded items don't have one, so they're left out rather than guessed.
Is this medical or dietary advice?
No. The amino acid score ignores digestibility (it's an upper bound on PDCAAS/DIAAS) and gives general, informational estimates only. Talk to a registered dietitian for personal advice. Everything runs in your browser — nothing you enter is uploaded.
