Why Do People Eat More Variety in Their Diets?

People who have more money generally feed themselves on more varied diet. If they had money, they would just be eating beans and fish. They don't need frankin casava that has ike a two gram higher protein count. And also, we as nations, are the ones withholding the money and there for the food. So what if we stop doing that? O it's so gross and so, in retrospect, so predictable.
