Who knew? Why we buy the foods we do

Do you buy a lot of the same foods week after week at the grocery store? Sure, we switch it up a little, but most of us have quite a few brands and foods that we're faithful to. Researchers are currently working on something I think would be really interesting: they're studying why we choose the foods we do when making selections at the grocery store.

Not only do we buy foods based on our income levels and what we know and/or believe about nutrition and health, but our ethnicity and gender also play a role. This is a pretty interesting article covering everything from how lower incomes mean higher sodium intake, to how men generally eat more fruits and vegetables than women.

Really? That last one surprises me.
