Design affects us whatever we are doing; the design and layout of a grocery store affects how we shop and what we buy. Lifehacker has a suggestion for healthier shopping: stick to the perimeter.
That's where all the fresh foods are. The less you find yourself in the central aisles of the grocery store, the healthier your shopping trip will be. Make it a habit--work the perimeter of the store for the bulk of your groceries, then dip into the aisles for staples that you know you need.
