Potato chips are a staple American comfort food and probably one of the first things that come to mind when you think about packing a light snack, so naturally, they're not so healthy for you. They're high in calories, most of which come from the oil the chips are cooked in, and they're high in fat. In the plus column, chip manufacturers have been reducing the unhealthy trans fat content for several years now. Some varieties are healthier than others are so look for low salt and/or baked varieties. Supermarkets typically devote an entire aisle to the wide variety of chips and chip-like products on the market. So it's likely you'll be able to find something that sates your hunger without clogging your arteries too much.
