Guía dietética para mujeres embarazadas utilizando DeepSeek-R1 y ChatGPT-4.0: un análisis comparativo

Advancements in artificial intelligence (AI) and natural language processing have enabled the widespread application of large language models. However, the ability of AI models to provide dietary guidance for pregnant women remains unclear. This study aims to explore the capabilities of DeepSeek-R1 and ChatGPT-4.0 in generating dietary plans for pregnant women with different activity levels.

Personalized diet plans were generated using DeepSeek-R1 and ChatGPT-4.0. Through calorie calculation, Diet Quality Index-International (DQI-I) assessment, and cost analysis, the dietary quality and cost performance were evaluated.

The requested caloric targets in DeepSeek's diet plans were superior to those of ChatGPT. All plans achieved a satisfactory DQI-I score (≥ 70). The "adequacy" score of DeepSeek-R1 was much higher (DeepSeek-R1 35.8 ± 0.7 vs. ChatGPT-4.0 33.9 ± 0.8, p < 0.001), while ChatGPT-4.0 performed better in the "moderation" aspect (ChatGPT-4.0 22.3 ± 2.2 vs. DeepSeek-R1 17.0 ± 3.4, p = 0.004). ChatGPT-4.0 demonstrated better performance in terms of cost-effectiveness (p = 0.017).

This study shows that DeepSeek-R1 and ChatGPT-4.0 can be helpful in providing personalized and reasonable dietary advice for pregnant women. In some aspects, such as food type adequacy, the emerging model "DeepSeek" performs better than ChatGPT.
