The Claim
The current body of evidence comparing plant and animal protein supplementation is restricted to soy and dairy sources, with the majority of trials using soy as the plant protein and dairy proteins (whey, casein, milk) as the animal protein, resulting in insufficient data to determine whether findings apply to other plant proteins such as pea, rice, or hemp.
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.
Most studies comparing plant and animal protein supplements have only used soy and dairy, so it is not known whether results from these studies apply to other plant proteins like pea, rice, or hemp.
See the scientific wording
The current evidence comparing plant and animal protein supplementation is limited to soy and dairy sources, with 17 of 18 trials using soy as the plant protein and dairy proteins (whey, casein, milk) as the animal protein, making it unclear whether findings generalize to other plant proteins such as pea, rice, or hemp.
Only two types of plant and animal proteins have been tested in human trials, so the biological effects seen with those specific proteins cannot be assumed to apply to other plant proteins with different amino acid profiles and digestion rates.
What the research says
1 studyThis study looked at protein supplements and found almost all the research used soy and dairy — it didn’t test pea, rice, or hemp protein at all. So it confirms we don’t know if those other plant proteins work the same way.
