Abstract
This study aimed to evaluate the nutritional composition and consistency of 1500 kcal daily diet plans generated by four generative Artificial Intelligence (AI) tools (ChatGPT-4, ChatGPT-4o, Mistral, and Claude) based on five popular diet types identified via Google Trends (keto, paleo, Mediterranean, intermittent fasting, and raw). Each AI model was prompted with standardized requests, and the resulting menus were analyzed using Nutrition Information System (BeBIS) (version 9.0) to determine energy, macronutrient, and micronutrient content. Nutrient composition differences across AI tools were statistically assessed using SPSS 24.0 (ANOVA, p < 0.05). Results showed significant variations between AI outputs, with energy values ranging from 1357 kcal to 2273 kcal and protein intake varying by up to 65 g across models. Notable inconsistencies were also found in micronutrients such as calcium, iron, and vitamin D. AI models often failed to meet targeted caloric levels and showed inconsistent adherence to diet-specific nutrient profiles. These discrepancies suggest limitations not only in the AI tools’ capabilities but also in their interpretation of user prompts. The findings highlight the need for improved prompt design, database integration, and AI training for safe and reliable use in personalized nutrition.
期刊介绍:
The Journal of Food Composition and Analysis publishes manuscripts on scientific aspects of data on the chemical composition of human foods, with particular emphasis on actual data on composition of foods; analytical methods; studies on the manipulation, storage, distribution and use of food composition data; and studies on the statistics, use and distribution of such data and data systems. The Journal''s basis is nutrient composition, with increasing emphasis on bioactive non-nutrient and anti-nutrient components. Papers must provide sufficient description of the food samples, analytical methods, quality control procedures and statistical treatments of the data to permit the end users of the food composition data to evaluate the appropriateness of such data in their projects.
The Journal does not publish papers on: microbiological compounds; sensory quality; aromatics/volatiles in food and wine; essential oils; organoleptic characteristics of food; physical properties; or clinical papers and pharmacology-related papers.
