When food shopping, picking the healthiest groceries can be tough. Say one bag of potato chips is "baked" while another is "kettle-cooked." Which is the better choice? (Turns out kettle-cooked is more nutritious.) A new system, being used in more than 750 supermarkets across the country, can help you figure that out. NuVal ranks every product in the store from 1 to 100 (100 being the healthiest) by evaluating more than 25 nutrients and other related factors. So we sorted through scores of popular snacks, from chips to cheese, to pull out the best.
