You never can eat only one. And the fat, salt, and carbs add up. For a crunchy treat with a little more health appeal, try nuts.
Their nutrients help your cells work, and their good fats keep you full and satisfied. Just keep an eye on portion size — they have fats, too.
You could also pop some popcorn. It’s high in fiber and low in calories — as long as you watch the butter. Either one will satisfy hunger better than potato chips.
