Part skim string cheese sticks
It’s hard to squeeze in your 3 daily servings of dairy when you’re cooped up in the car all day. Calcium-rich snacks like string cheese can help. Grab a couple of these and you’ll get as much calcium as you would from a glass of milk. What’s more, their protein (one piece supplies 7 grams) helps you focus and stay alert behind the wheel. For a balanced snack, pair them with a bag of baby carrots.
