Essential Amino Acids (EAAs) Explained

Protein quality isn't just about grams. It's about covering your essential amino acids. Here's what you need to know.

What are essential amino acids?

Amino acids are the building blocks of protein. Your body uses 20 different amino acids, but it can only make 11 of them on its own. The other 9 must come from food — these are called essential amino acids (EAAs).

The 9 Essential Amino Acids:

Why do EAAs matter for vegans?

Different plant foods have different amino acid profiles. Some are higher in certain EAAs, lower in others. The good news: variety across the day balances everything out.

You don't need to track individual amino acids — just eat a mix of protein sources and you're covered.

Which plant foods are strong in which EAAs?

Lysine-rich foods

Legumes (lentils, chickpeas, beans), tofu, tempeh, quinoa

Methionine-rich foods

Grains (rice, oats), seeds (sunflower, sesame), nuts

Pairing legumes with grains across the day naturally covers both limiting amino acids.
