Nutrients

November 2024

Université Clermont Auvergne, CNRS, LaPSCo, Physiological and Psychosocial Stress, CHU Clermont-Ferrand, University Hospital of Clermont-Ferrand, Preventive and Occupational Medicine, Witty Fit, F-63000 Clermont-Ferrand, France.

Objectives: The objective of this investigation was to compile existing observational research and quantify the potential association between ultra-processed foods (UPFs) and the risk of insomnia using meta-analysis.

The association between Planetary Health Diet Index and the risk of colorectal cancer: a case-control study.

Sci Rep

November 2024

Department of Community Nutrition, Faculty of Nutrition and Food Technology, National Nutrition and Food Technology Research Institute, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Background Despite the beneficial effects of a plant-based diet on colorectal cancer (CRC), no study has yet investigated the relationship between a Planetary Health Diet Index (PHDI) and CRC in the Iranian population. Therefore, the present case-control study aimed to assess the relationship between this index and CRC. Methods The current research was conducted on 71 patients with CRC (case group) and 142 (control group) admitted to hospitals in Tehran, Iran.

  • The study investigates the link between transient global amnesia (TGA) and dietary intake of vitamin B12, aiming to understand how diet might influence this form of short-term memory loss.
  • Conducted with 258 individuals with TGA and 520 without in Sabzevar, Iran, researchers used a Food Frequency Questionnaire to assess vitamin B12 intake and employed logistic regression models for analysis.
  • Findings indicate that higher dietary intake of vitamin B12 is associated with a lower risk of TGA, suggesting that vitamin B12 deficiency could be a concern for those at risk; further research is recommended to explore this relationship.

  • The study focuses on the ApoB insertion/deletion genetic variant (rs11279109) and how it may affect cardio-metabolic markers and obesity, particularly in individuals with type 2 diabetes mellitus (T2DM).
  • Researchers aimed to explore the interaction between this genetic variant and dietary acid load (DAL), which is calculated using methods such as potential renal acid load (PRAL) and net-endogenous acid production (NEAP).
  • Findings suggest that individuals with the del/del genotype and high PRAL intake exhibited lower levels of harmful cholesterol and triglycerides, indicating a complex relationship between genetics, diet, and metabolic health in T2DM patients; further research is needed to confirm these results.

  • Non-alcoholic fatty liver disease (NAFLD) is becoming common among overweight and obese children, and this study examines how fructose and fiber intake, along with physical activity, relate to NAFLD.
  • Conducted with 378 children aged 6-13, the study found that 35% had NAFLD, and while fructose intake showed no significant link to the disease, higher fiber intake from legumes and nuts was associated with a reduced risk.
  • The findings suggest that while fiber could help prevent NAFLD, the exact role of physical activity remains unclear, indicating the need for further research.
