In some cases eating right wins:  water is cheaper than soda. eating less is cheaper, duh making your own food can be cheaper if you do it right In some cases eating right or way too healthy does get expensive: If you fill up on produce, you don't get filled up very much for the price of things. If you go to the packaged foods, the healthy stuff is always more expensive or has less in the box.  If you're in to natural and especially organic foods, that's an added cost.
