A high-fat, iron (Fe)-deficient Western diet induces obesity and dysregulates Fe metabolism. We compared the influence of Lactiplantibacillus plantarum and Latilactobacillus curvatus with and without Fe supplementation on duodenal Fe uptake under high-fat diet conditions. ⋯ L. plantarum and L. curvatus supplementation shows some potential to enhance duodenal cellular Fe uptake in rats on a high-fat, Fe-deficient diet.

Individuals experiencing higher stress levels tend to consume fewer fruits and vegetables compared to their less stressed counterparts. Thus, to promote fruit and vegetable (FV) consumption, action planning has been proven effective in translating behavioral intentions into actual dietary behaviors. This study aims to evaluate a 7-day intervention designed to improve FV planning and intake, while also examining the role of stress. ⋯ These findings confirm the positive impact of the planning intervention on improving FV intake, particularly for individuals with low stress levels, and highlight stress as a barrier to health behavior change that warrants further attention in future studies.

To evaluate the association between consumed non-nutritive sweeteners (NNS) and gestational diabetes mellitus (GDM) in a cohort of pregnant women from Santiago, Chile. ⋯ The consumption of NNS, particularly sucralose, is associated with an increased risk of GDM in pregnant women. Further studies are essential to validate these results in other contexts and to guide future recommendations for healthier dietary practices among pregnant populations.

Dietary fiber (DF) can be separated from food and convenient to take, and has an important role in diabetes prevention, but long-term intervention data are lacking. This study evaluated the long-term benefits of DF supplementation on body composition, glucose-lipid metabolism, and clinical regression in middle-aged and elderly patients with prediabetes. ⋯ DF supplementation can reduce the degree of central obesity, the levels of FPG and 2h PG, and the incidence of diabetes in middle-aged and older patients with prediabetes.
