Energy bars are the perfect pre-workout snack, right? Not always. Many energy bars are filled with high fructose corn syrup, added sugar, and artery-clogging saturated fat. Plus, some bars (particularly meal replacement varieties) contain more than 350 calories each―a bit more than "snack size" for most people. It is a good idea to fuel up with a mix of high quality carbs and protein before an extended workout or hike. Choose wisely: one-quarter cup of trail mix, or 1.5 oz. of low-fat cheese and three to four small whole-grain crackers. Or, make your own healthy granola bars and trail mix with these recipes.
