Food predilection is linked to variants in the hepatokine ''Fibroblast Growth Factor-21" gene (FGF21); with rs838133 linked to the sweet tooth in Caucasians. The effect of FGF21 variants on food intake is still unclear in other populations. A cohort of 196 healthy Emirati subjects was investigated [age: 30.34 ± 9. 75yrs (44.4% males)]. The FGF21 rs...
