Seattle’s Fresh Bucks program boosts food security and diet but benefits fade when funding ends

A lottery-based cohort study of Seattle’s Fresh Bucks program found that providing a $40 monthly fruit and vegetable benefit improved food security by 5.5 percentage points and increased daily produce consumption by 7.5 percentage points, while disenrollment reversed these gains. These findings highlight the potential of healthy food benefit programs to reduce nutrition-related disparities in low-income populations.

Gut bacteria and insomnia influence each other in small but significant ways, study shows

Scientists used Mendelian randomisation to explore the two-way relationship between gut microbiota and insomnia, analyzing GWAS data from over 386,000 individuals and two major microbiome cohorts. The study found only limited taxa surviving strict correction, suggesting small but causal links that highlight the gut–brain axis in sleep health.

Can AI help you eat healthier?

Researchers developed and validated an AI-based nutrition recommendation system (AINR) that generates weekly Mediterranean meal plans tailored to individual needs and dietary restrictions. Tested on 4,000 simulated users, the system achieved high accuracy in calorie and nutrient targets but struggled with profiles involving milk and nut allergies.
