While shopping at the grocery store, all it takes to make a bad choice is one swipe at the cash register.

There was a time when spending included more than a bank account and a receipt. Consumers carefully shelled out paper money from their wallets and purses, witnessing dollars and cents leave their possession for good, bad and ugly decisions. (See a special report on the science of appetite.)

In an increasingly debit- and/or credit-based economy, the Journal of Consumer Research has brought a new study to the kitchen table, linking bank-card usage with impulsive food choices. The experiment observed 1,000 people over a six-month period, with results suggesting that paying cash can cut “vice” foods out of your grocery bill. (See nine kid foods to avoid.)
