Nutrition science explores how the food we eat shapes our health, from cellular function to long-term disease prevention. This field moves beyond simple dietary advice to investigate complex biological mechanisms, nutrient interactions, and the impact of eating patterns on public well-being. Because research evolves rapidly, staying current with the latest findings is essential for understanding what truly drives better health outcomes.
At Gist.Science, we monitor medRxiv to ensure you never miss a breakthrough in nutrition research. We process every new preprint uploaded to this category, transforming dense scientific manuscripts into both accessible plain-language overviews and detailed technical summaries. This dual approach allows everyone from curious readers to specialists to grasp the significance of emerging data without getting lost in jargon.
Below are the latest papers in nutrition, freshly processed and ready for you to explore.
This cross-sectional study in urban Kathmandu Valley, Nepal, reveals that 3% of school-going adolescents experience the double burden of malnutrition, a condition significantly driven by low nutritional knowledge, poor diet quality, and specific socio-demographic factors.
This study demonstrates that a machine-learning classifier trained on nutrient composition can effectively transfer across different food databases to identify ultra-processed foods and rank processing intensity, even though assigning all four NOVA groups remains challenging due to inherent definition ambiguities.
An analysis of the 2021-22 Cambodia Demographic and Health Survey reveals that while 57.2% of women aged 15-49 achieved minimum dietary diversity, underweight status was not significantly associated with dietary diversity despite notable geographic variations and the coexistence of underweight with overweight and obesity.
This descriptive, analytical, and correlational study of 160 physical education students found that while high nutritional awareness is strongly associated with specific eating behaviors (such as reduced emotional and external eating but increased restrained eating), body mass index and estimated resting metabolic rate show weaker links, suggesting that nutrition education should be tailored to sex and academic level differences.
Using nationally representative data from the 2022-2023 Multiple Indicator Cluster Survey, this study reveals that 8.4% of under-five children in Yemen suffer from concurrent wasting and stunting, a condition significantly driven by male sex, geographic location, household poverty, food insecurity, recent diarrhoea, and inadequate WASH facilities, thereby underscoring the urgent need for integrated, multi-sectoral interventions.
This exploratory, double-blind, randomized, placebo-controlled trial found that while daily Lab4 probiotic supplementation did not yield statistically significant reductions in upper respiratory tract infections or related healthcare utilization among 104 healthcare workers, it was associated with improved self-reported wellbeing and trends favoring reduced illness that warrant further investigation in a larger, powered study.
This qualitative study of 35 retailers in urban poor areas of Kuala Lumpur identifies consumer demand, profitability, and supply constraints as key factors influencing stocking decisions, while highlighting price, shelf life, and limited supply as major barriers to offering healthy foods, thereby underscoring the need for collaborative interventions among retailers, suppliers, and policymakers to improve the local food environment.
The SCCSS-Nutrition study identified five distinct dietary patterns among adult childhood cancer survivors that were influenced by sociodemographic and lifestyle factors but showed no significant association with cardiovascular disease risk profiles.
This randomized controlled trial demonstrates that daily supplementation with whole-fruit feijoa powder (Feiolix), particularly at a high dose of 1,150 mg, significantly improves glycemic control, insulin resistance, and lipid profiles while reducing body weight and BMI in overweight adults with prediabetes compared to placebo, without altering GLP-1 levels or causing adverse events.
By analyzing over 50,000 free-living meals, this study demonstrates that despite high meal-to-meal variability, short-term glucose monitoring can reliably identify stable, individual-specific traits—particularly an overall tendency for larger glucose excursions—that are reproducible and predictive of standardized responses, offering a viable method for personalizing glucose management.
