Abstract

Purpose of review Artificial intelligence has reached the clinical nutrition field. To perform personalized medicine, numerous tools can be used. In this review, we describe how the physician can utilize the growing healthcare databases to develop deep learning and machine learning algorithms, thus helping to improve screening, assessment, prediction of clinical events and outcomes related to clinical nutrition. Recent findings Artificial intelligence can be applied to all the fields of clinical nutrition. Improving screening tools, identifying malnourished cancer patients or obesity using large databases has been achieved. In intensive care, machine learning has been able to predict enteral feeding intolerance, diarrhea, or refeeding hypophosphatemia. The outcome of patients with cancer can also be improved. Microbiota and metabolomics profiles are better integrated with the clinical condition using machine learning. However, ethical considerations and limitations of the use of artificial intelligence should be considered. Summary Artificial intelligence is here to support the decision-making process of health professionals. Knowing not only its limitations but also its power will allow precision medicine in clinical nutrition as well as in the rest of the medical practice.

Analysis

Why This Paper Matters

This review is significant as it bridges the gap between artificial intelligence and clinical nutrition, a field that has traditionally relied on manual assessments and subjective judgments. By showcasing concrete applications—such as using machine learning to predict feeding intolerance in ICU patients or to identify malnourished cancer patients from large datasets—the paper demonstrates that AI is not a distant future but a present reality. For AI practitioners, it highlights the growing need for domain-specific models that can handle the complexity of clinical data, including electronic health records, microbiota profiles, and metabolomics.

The paper also underscores the shift toward personalized medicine, where AI can tailor nutritional interventions based on individual patient data. This is particularly relevant as healthcare systems worldwide grapple with rising costs and the need for efficiency. By providing a comprehensive overview of current AI applications, the review serves as a roadmap for researchers and clinicians looking to integrate AI into their workflows, while also cautioning against over-reliance without proper validation.

Technical Contributions

The paper's technical contributions are primarily conceptual, as it is a review rather than a novel algorithmic study. However, it systematically categorizes AI applications in clinical nutrition:

  • Screening and Assessment: Use of deep learning on large databases to improve malnutrition screening and identify at-risk populations (e.g., cancer patients, obese individuals).
  • Predictive Modeling: Machine learning models for predicting enteral feeding intolerance, diarrhea, and refeeding hypophosphatemia in intensive care, enabling proactive interventions.
  • Outcome Prediction: AI models that predict cancer patient outcomes, potentially guiding treatment decisions.
  • Integration of Omics Data: Machine learning to integrate microbiota and metabolomics data with clinical variables, offering a holistic view of patient health.
  • Ethical Framework: Discussion of limitations, including data privacy, algorithmic bias, and the need for clinician oversight.

Results

As a review, the paper does not present new experimental results but synthesizes findings from prior studies. It reports that AI has achieved success in improving screening tools and identifying malnourished patients, with examples from cancer and obesity. In intensive care, machine learning has accurately predicted enteral feeding intolerance and refeeding hypophosphatemia, though specific metrics are not detailed. The paper also notes that AI-enhanced integration of microbiota and metabolomics profiles has improved outcome prediction in cancer patients. These results collectively suggest that AI can augment clinical decision-making, but the lack of quantitative benchmarks in the review limits direct comparison.

Significance

This paper is significant for the AI community as it highlights a high-impact application domain with clear clinical needs. It encourages AI researchers to develop interpretable and robust models that can operate in real-world healthcare settings, where data is noisy and heterogeneous. The emphasis on ethics and limitations is crucial, as it aligns with broader AI governance discussions. For clinical nutrition, the paper signals a paradigm shift toward data-driven, personalized care, potentially improving patient outcomes and reducing healthcare costs. As AI continues to evolve, this review sets the stage for future research that combines advanced machine learning techniques with domain expertise to achieve precision medicine.
