People are led to believe that their genetics are to blame instead of what they're eating.  Doctors are more willing to suggest a pill rather than promoting people to change their lifestyles.  The fact that most men and women are working 40+ hours a week, no one has time to cook meals at home and will stop and get fast food at the end of the day.  It doesn't help that all restaurants use seed oils to cook with, which are probably the worst thing a human can consume.  Also, the government has everyone thinking that red meat and eggs are bad for us when in fact they are the most nutritious food we can consume.  Veggies and whole grains are pushed on people by doctors and the end result is higher blood pressure, more weight gain, and lack of important vitamins and minerals.  I know at my work people are more likely to grab a pack of chips for lunch and keep working, rather than sit down and eat something with some protein in it
