Meat-Eating Genes

A new study shows that when humans began eating meat, they developed special genes to offset the high intake of cholesterol.  A natural question then, is why do so many meat-loving Americans have high blood cholesterol and cardiovascular disease?  The study's author suspects that this is due to constant eating of fatty meat, while our hunter-gatherer ancestors had to work hard just to find lean game meat.  I also suspect that the low intake of fruits and vegetables of most Americans is a contributing factor as well.
