What we have so far
PDCAAS caps its own score at 1.0, so it cannot tell a good protein from an excellent one. DIAAS does not cap, and it demotes most plant proteins.
This star is on the map because the show intends to take the question apart properly — the trials, how it is actually tested, whether the thing sold is the thing studied. That work is not done yet, and nothing here should be read as a conclusion. When the investigation is published it will appear on this page.
