APOA1 and metabolic syndrome: The risk of MetS was not homogenous in APOA1 rs670 genotypes, across quartiles of sugar and nut group intakes; A allele carriers of rs670 had lower odds of MetS in higher quartiles of sugar group intake (OR: 3.0, 1.60, 1.52, 1.30, P trend<0.01) (P interaction= 0.02), compared to the GG genotype (OR: 1, 1.70, 1.31, 2.20, P trend=0.46).
