Along with fried and baked goods, snack bars at summer sporting events also offer pre-packaged foods. Keep an eye out for granola bars, a combination of oats, nuts, seeds and dried fruit. Avoid ones with chocolate chips or drizzles!
Choose granola bars over energy bars, which typically are higher in calories. They are designed to give the body energy, but since you're just going to be sitting down on the stands, those extra calories aren't needed.
