Hungry Shoppers Make Poor Food Choices
Wondering how all those chips and cookies ended up in your supermarket cart? You may be hungry. Researchers asked 68 people to fast for five hours, then fed half of them wheat crackers while giving the rest nothing. The participants next did some online grocery shopping. Those who hadn’t eaten bought higher-calorie foods than those who’d enjoyed some pre-shopping crackers. The researchers also tracked the grocery store purchases of random people from 1 to 4 p.m. (the after-lunch crowd) and from 4 to 7 p.m. (the hungry before-dinner crew). The later shoppers picked fewer lower-calorie foods than those who shopped in the early afternoon, again supporting the idea that hungry people make less-healthy choices at the grocery store.
