What to watch with FUT2 and gut health?

The rs5082 variant in APOA2 (G allele) has been associated with higher BMI in individuals consuming high saturated fat, based on observational and GWAS data. The effect size is small, and the evidence is rated human-moderate. A low-saturated-fat diet is already recommended for cardiovascular health. Therefore, this genetic information alone does not mandate a personalized diet change. It may provide a slight additional incentive, but overall diet quality and lifestyle remain far more important. Caveat: The association is observational, not causal. Do not base major dietary decisions solely on this SNP; consult a healthcare professional.
