Precision Nutrition: A brief perspective of what is known and what to investigate

Angélica Irais Borja Magno — 2026-05-04

Precision Nutrition (PN) is an emerging field dedicated to providing dietary interventions based on the unique interplay between an individual's biology and their environment. While General Nutrition (GN) overlooks interindividual differences, PN leverages this variability to optimize health outcomes. This review synthesizes current evidence evaluating the impact of PN compared to GN in the management of diabetes, obesity, cancer, and infertility. Additionally, it outlines critical areas for future investigation.

Advances and Challenges in Nutrition Research: A Field in Constant Evolution

Javier A. Magaña Gómez — 2026-05-04

Nutrition research has evolved significantly, transitioning from broad epidemiological approaches to more precise models integrating genetics, microbiota, and artificial intelligence. Contemporary advancements in fields such as precision nutrition, functional foods, and big data analytics have transformed our understanding of the intricate relationship between diet and health. However, these developments also present substantial challenges, including the proliferation of misinformation in nutritional science, the complexity of accurately assessing dietary intake, and the imperative to enhance the reproducibility of research findings. Moreover, individual variability in dietary responses further complicates the generalization of nutritional recommendations. Addressing these challenges requires a concerted effort to strengthen methodological rigor, improve evidence-based nutrition education, and foster interdisciplinary collaboration. Additionally, advancing the standardization of data collection and database management is essential to facilitate the generation of robust, applicable knowledge. Ultimately, nutrition research aims not only to elucidate the effects of dietary factors on health but also to translate scientific insights into effective strategies that enhance public health and quality of life. This review describes the evolution and recent advances in nutrition research, as well as the challenges it faces, with the aim of enhancing its impact on public health.

Ethics and Artificial Intelligence Applied to Nutrition Research

Rocío Angélica Salinas Osornio — 2026-04-30

Ethics as a discipline is defined as the conduct of human beings in relation to their responsibility for what others expect them to do voluntarily, so its importance lies in knowing what is right and wrong as individuals and as society. The Belmont Report considers three universal basic principles for the ethical conduct of human research: respect for people, charity and justice. Research processes in nutriology may present some ethical dilemmas between the researcher and the subject of study, that are recommended for treatment within an ethics committee following the basic principles of bioethics and good clinical research practices. There are several applications of artificial intelligence (AI) that can be used in nutrition research projects or clinical practice, based on hybrid human-machine decision models. However, its use presents a number of risks and challenges that are worth considering. Conclusion: Scientific research requires careful attention to ethical principles, promoting observance of autonomy, beneficence, non- maleficence, justice, fairness, scientific integrity and accountability throughout the research process. The impact of AI on nutriology is related to biased self-information, greater benefits in adherence to treatments and better quality of life for subjects.

An appropriate approach for body weight for all stages of life

Ana Olivia Caballero Lambert — 2026-04-30

In the international context, attention is drawn to what has been proposed as "clinical obesity," as clinicians, researchers, and patients have highlighted the harm caused when a person is stigmatized and treated with weight bias. Regardless of age, the focus on what is now known as the "diet culture" affects the physical, mental, social, and spiritual health of individuals, with greater emphasis on those in the pediatric group, due to their inherent vulnerability. Even so, it is important not to disregard the use of body weight when assessing a patient's nutritional status. It is recommended to use a combination of both quantitative and qualitative measures that integrate anthropometric, clinical, psychological, social, and environmental aspects to minimize harm to the patient as much as possible and, instead, foster their trust in healthcare services.

Importance of early diagnosis and treatment of severe hyponatremia due to the use of diuretics in patients with heart disease such as hypertension and heart failure. presentation of a clinical case

Arturo Villagrán Ruiz de la Peña — 2026-05-04

Heart disease is becoming more frequent and includes ischemic heart disease and heart failure as the predominant complication of the latter; which demand the use of medications that, fortunately, are very effective. Within the treatment of heart disease, both the use of diuretics of any kind and low-sodium diets must be handled with great care since their indiscriminate and inexperienced use can expose the patient to critical conditions that warrant urgent hospitalization; Hyponatremia can even lead to coma, first including headache, confusion, stupor, and seizures. We present the case of a 72-year-old female patient hospitalized for severe drowsiness after having been exposed to the intense sun for several hours, reporting significant sweating. She was admitted with clinical data of dehydration with serum values of sodium of 119 mmol/L, potassium of 4.6 mmol/L and chlorine of 85 mmol/L.. One of the most appropriate management of severe hyponatremia should be progressive doses of 0.9% saline solution, measuring serum sodium, potassium and chlorine every 4 hours, causing the patient's improvement successfully. On the other hand, management with a low-sodium diet even in heart failure is no longer recommended; It is suggested that the amount of sodium ingested should not be less than 5 g per day.
