The results showed that the causal relationship between people with juice preference (PP.H3 = 0.045, PP.H4 = 0.852, PP.H3 + PP.H4 > 0.80) and soft cheese preference (PP.H3 = 0.085, PP.H4 = 0.728, PP.H3 + PP.H4 > 0.80) and NAFLD risk was driven by rs28429148, which corresponds to the fat mass, obesity‐related (FTO) gene (Figure 4 and Table S4). This evidence concerns the gene FTO and obesity due to melanocortin 4 receptor deficiency.
