FAT1 and metabolic dysfunction-associated steatotic liver disease: Vaccenic acid, OA, and overall monounsaturated FA were reduced with dietary ω-3 PUFA, while the Fat-1 genotype did not have this effect (P = .05) and finally while the ω-6/ω-3 PUFA ratio (a variable within the NAFLD factor) was significantly lower in both ω-3 PUFA models, dietary ω-3 PUFA had a greater effect (Table S1).
