How we evaluate research

We do not treat human trials, animal experiments, laboratory models or environmental modeling as interchangeable.

Scientifically reviewed: September 25, 2026

Our evidence checklist

For each study we aim to record design, population or model, sample size, intervention, comparator, duration, main findings, limitations, funding and relevant conflicts of interest.

How we write conclusions

Where findings disagree, we describe the disagreement rather than selecting only the result that favors yeast protein. We avoid translating laboratory effects into human health claims. Corrections and substantive updates should be dated.

Editorial principle

Be enthusiastic about the possibility; conservative about the evidence.
