You already know not to grocery shop hungry, but the type of snack you have may make a difference. In a recent study, shoppers who sampled an apple selected 28 per cent more fruits and vegetables than those who didn't get a sample at all.

The study, published in Psychology & Marketing, involved a real apple (or cookie, for some lucky volunteers) and an imaginary shopping trip. So the technique hasn't been field-tested, but it fits with previous research on priming: reminding you that fruit is delicious makes you want more fruit.
And it's an easy tip to implement: just snack on an apple (or another fruit or veggie of your choice) before you go shopping. Pair this with a (water) drinking game and see if you come out of the store with more healthy choices.
