Where this applies
A cross-sectional study in which 100 nutrition questions were taken from public online forums where registered dietitians had answered, each paired with a ChatGPT-4o answer, and eight licensed dietitians, blinded to the source, rated them. AI answers scored higher for quality (4.48 against 2.56 on a 5-point scale), empathy (4.62 against 3.21) and overall performance; dietitians' answers were more variable. Forum answers are not counselling sessions.
What this means
For written answers to common questions, AI already meets the profession's own standard better than many dietitians do online.
What it does not yet show
Forum posts are a weak comparator for clinical counselling, and the study rates text, not behaviour change.
What you can check
Open the mHealth study comparing AI and dietitian nutrition responses and find "public online forums where RDs had provided answers".
Does it change the assessment?
No — and this stage does not move it either. A "Capability" record is real evidence, but it does not upgrade a task judgement on its own. The 1 linked judgement above stand where they were.
