In October last year, the Washington University School of Medicine in St. Louis published a study indicating that a preference for vegetarianism could be inherited. Based on whole genome data from the UK Biobank, the study compared 5,324 strict vegetarians to 329,455 control subjects and found that at least one specific single nucleotide variation on chromosome 18 is associated with vegetarianism. Additionally, 201 other variants were identified that are presumably significant. Specifically, 11 genes were pinpointed, which are likely linked to the inclination towards vegetarian food.

So, blame it all on genetics 🙂
