Gut microbiome composition explains a significant proportion (4-6%) of the variance in blood triglyceride and HDL levels, independent of age, sex, and host genetics.
Your gut bacteria influence your cholesterol and triglyceride levels independently of your genes. While the effect size is moderate, targeting gut health through diet or probiotics may offer a supplementary strategy for managing lipids, particularly HDL and triglycerides.
GoodSupportsHIGH confidence
Cross-validation analysis revealed that microbiota explain 4.5% of the variance in body mass index, 6% in triglycerides, and 4% in high-density lipoproteins, independent of age, sex, and genetic risk factors.
Why this rating
Large-scale human cohort (n=893) with rigorous statistical controls (age, sex, genetics), though observational.
