On a road trip during summer, but still want to stick to some semblance of a healthy eating plan? CNN.com offers these tips:

At a gas station or convenience store:

CNN warns this is the last resort for a snack or meal, but there are ways to beat the high-calorie, sugar-high system.

Go straight to the refrigerator. Pick up string cheese, yogurt (and nuts or dried fruit for added texture and flavor), water, orange juice and unsweet tea. Nothing good in the fridge to eat? Try nuts, dried fruit and whole-wheat crackers.

If you feel the need to splurge, get the nugget pretzels–they’ll be more satisfying since they take longer to eat. Also, animal crackers and Teddy Grahams have fewer calories than other cookies.

At a rest stop:

Larger rest stops house a coffee or sandwich shop. Go for a fruit and cheese plate, pasta salad, or a wrap.

If it’s breakfast time, get eggs in a whole-wheat wrap, oatmeal or a yogurt parfait. Or at Dunkin’ Donuts, choose the egg white turkey sausage flatbread sandwich.

At the coffee shop, stick to regular iced or hot coffee. Need the latte? Choose nonfat milk.

At a fast food restaurant:

At McDonald’s, choose the caesar salad (nonfat dressing) with grilled chicken. At Wendy’s? Try the mandarin chicken salad.

Tempted by the burgers and fries? That’s all right too. Just choose a single-patty burger, no cheese or special sauce. And stick to small fries.

At a roadside diner:

At breakfast, choose oatmeal or a veggie omelet. If you get whole-wheat toast, ask for it dry or else they’ll slather it with butter.

At lunch or dinner, try the soup of the day, stew, chili or turkey sandwich (no mayo). If you want something heavier, get the meatloaf or roasted turkey plate. Ask for double veggies instead of mashed potatoes.

At an Italian or pizza joint:

Try the small pasta with marinara sauce or veggie-laden pasta primavera with a green salad. As for the pizza, if you need two hands to hold the slice, only eat half. And skip the meat toppings, as they’re loaded with sodium and saturated fat.

At a Mexican restaurant:

Avoid the word “crunchy.” Instead of sour cream, eat the guacamole (they’re not likely to give you so much that you’ll regret it — this condiment is expensive for them). Try to hold off on the cheese, but if it’s a must, ask for half of the normal amount.

At a sandwich or sub shop:

Choose whole-wheat bread and lean meats, and load up on the veggies. Skip the high-fat mayo for oil and vinegar, mustard, or low-cal spicy or honey mustard. Avoid the Italian subs, whose pepperoni, salami and bologna are high in sodium and saturated fat.
