The best fair foods are those that contain at least one healthy ingredient: kettle corn, candy apple, watermelon, shish-ka-bob, roasted chicken, veggie burrito, homemade pretzel, or fresh lemonade.  A snow cone, made mostly of water, also fills the bill.  Traditional fair food is full of grease and the portions are huge. To avoid grease, steer clear of deep-fat fried foods, like funnel cakes, and fatty meats, like Philly cheesesteak and racks of ribs.  Practice portion control by sharing food with a friend and by ordering items that are naturally small, like a single corn dog.
