Credit cards users eat more junk food

Using cash and not credit cards to buy groceries leads to lower consumption of junk food, according to US researchers.

Consumers are more inclined to buy unhealthy, impulse items such as cola drinks and chocolate biscuits when paying with credit card because that method of spending weakens impulse control.

The researchers suggest technological advances might be able to counteract the current disconnect between credit card spending and junk food purchasing.
