"Your political beliefs shape your opinions on obesity, says a study from the University of Kansas. Republican? You probably believe that eating and lifestyle habits cause obesity, regardless of how much you weigh. Democrat? Your probably believe that being fat is just a roll of the genetic dice, and you're fat because of genetic factors.
And what makes you a liberal or a conservative? Your genes may influence your beliefs. A study from the National University of Singapore (NUS) found that women who possessed a 4R/4R variant of the DRD4 gene — also called the 'adventure' gene — were more politically conservative.
'Our findings have shown that despite a country's political system or even culture, political ideology is in part hardwired by our genes,' said researcher Chew Soo Hong."
