For years we've heard that if you're of African descent you are predisposed to a litany of disorders such as diabetes, obesity and heart disease. These are always attributed to genetics, and as we all know you can't do anything about genetics.
As it turns out these metabolic disorders can be attributed much more to societal norms that manifest as biology. In this day and age with what we know about the genetics of our species we should also know that categorizing biological differences based upon the outdated terminology of race is teetering on the edge of pseudoscience.
What is really needed is to shrink the social and economic disparities that lead to poor dietary decisions. If you have never been taught about proper nutrition you will not make good choices. If you can't afford those good choices you will end up eating the cheap processed and sugar-filled junk that will kill you in the end.
Telling people that easily preventable health issues are genetic does them a great disservice. The mindset becomes, "If I can't change it why even try?" This way of thinking becomes perpetual, ultimately affecting generation after generation.
