The Claim
Yeast protein exhibits lower true protein digestibility (TPD) and true ileal digestibility (TID) compared to animal proteins (whey) and plant proteins (soy, wheat, pea) in both in vivo (growing rats) and in vitro (INFOGEST) digestion models.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
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 is less digestible than whey, soy, wheat, and pea proteins. This was measured in rat feeding studies and in lab simulations of digestion.
See the scientific wording
Yeast protein has lower true protein digestibility (TPD) and true ileal digestibility (TID) compared to animal proteins (whey) and plant proteins (soy, wheat, pea) in both in vivo (growing rats) and in vitro (INFOGEST) digestion models.
Yeast proteins are wrapped inside tough cell walls made of compounds like glucan and mannoprotein. These walls resist breakdown by human digestive enzymes, so the proteins stay trapped and pass through the gut without being fully digested. This makes yeast protein less digestible than proteins from whey, soy, wheat, and pea, which lack such thick, protective walls.
What the research says
1 studyThe study found that yeast protein is harder for the body to break down than proteins from whey, soy, wheat, and pea, which matches what the claim says.
