The Claim
Yeast protein powder contains higher levels of essential amino acids (36.14 g/100g) and branched-chain amino acids (16.21 g/100g) compared to legume protein powders (soybean, pea, faba bean) which contain 30.76–32.29 g/100g and 14.16–15.45 g/100g respectively, suggesting a superior amino acid profile for human nutrition.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Yeast protein powder contains more essential amino acids and branched-chain amino acids than legume protein powders like soy, pea, and faba bean. This means yeast protein has a better amino acid profile for human nutrition.
See the scientific wording
Yeast protein powder (YPS) contains significantly higher levels of essential amino acids (36.14 g/100g) and branched-chain amino acids (16.21 g/100g) compared to legume protein powders from soybean, pea, and faba bean (30.76–32.29 g/100g and 14.16–15.45 g/100g respectively), indicating a superior amino acid profile for human nutrition.
Yeast protein has more of the building blocks your body needs to make muscle and other tissues. When you eat this protein, your body breaks it down and absorbs those building blocks into your blood. With more of the essential building blocks available, your body can build more protein.
What the research says
1 studyThe study found that yeast protein powder has more of the essential amino acids our bodies need (36.14 grams per 100 grams) than bean proteins (30.76-32.29 grams), so the claim is correct.
