A study published in the journal Nutrition evaluated ChatGPT’s ability to classify 1,168 foods into NOVA processing categories, comparing its output with a trained nutrition researcher. The model achieved about 98% overall accuracy, with 94.7% sensitivity for ultra-processed foods and roughly 99% specificity, suggesting LLMs could speed dietary analysis while experts retain oversight.
