Harvard University researchers have systematically analyzed 27 studies from 10 countries that examined food prices at the retail level by healthfulness. The price gap they discovered is it costs about $1.50 per day more for a healthful diet than an unhealthful one. While less than some might expect, for the economically disadvantaged this could be a barrier. Yet, this amount is less than a espresso or big gulp of soda! What they didn't really compare were healthy vegetarian diets.
