Djuric Z, et al. – In a cohort of healthy adults (17 men and 30 women; aged 26–75 years), researchers performed a secondary analysis of the Fish Oil Study to investigate the relationship between interindividual variations in colonic bacteria and variability in the attenuation of colonic prostaglandin E₂ (PGE₂) concentrations following personalized supplementation with ω-3 (n–3) fatty acids. In all, little influence of dietary supplementation with ω-3 fatty acids on intestinal bacteria was evident among study participants. However, reductions in colonic PGE₂ were significantly predicted by an increase in diversity in the luminal brushings.
