I think the question should also be asked, how much other sugar are you consuming? Eat dessert? Cook with sugar? Eat refined flour? Odwalla and Cliff Bars aren't the worst thing you can eat, they're much cleaner than most similar products, but overdoing it is questionable. Cliff bars were invented for off road cyclists who were expending a lot of energy and burning it quickly. Are you? Personally, I'd say Gymdandee's suggestions are a lot healthier for everyday eating, though I'd avoid cereal bars as they add a lot of sugar of some kind and stick to the oatmeal or high quality cold cereals that use grains other than wheat. I personally use a millet and rice flake cereal, add some oat bran and sprouted grain and bean granola-like cereal with soy milk, but you can use almond milk if you like, a piece of fruit and some nuts to balance out the protein when I choose to eat cereal.
Healthy breakfast on the run is possible with the right supplies on hand. Cereal and cereal bars are a good source of fiber, grain and energy for breakfast. Some cereals provide fruit and nuts in the mixture, which adds servings of other food group. Take care not to choose high-sugar, refined cereals; these tend to have higher calories and cause a sugar crash, resulting in mid-day fatigue. Cereal bars that contain oatmeal, bran and fruit offer sensible options on the go. Grab a piece of fruit such as an apple, orange or banana to pair with the cereal.
Fresh fruit smoothies with added protein powder provide a high-energy and high-protein breakfast option. The sugar supplied by the real fruit is a natural carbohydrate. Blend the smoothie with fruit juice, sherbet or frozen yogurt for flavor. Try a whole wheat pita or tortilla stuffed with scrambled eggs and cheese for a quick and healthy option. A bowl of oatmeal topped with blueberries or a side of dried cranberries offers protein and carbohydrates. The key is to choose whole grains and natural fruits and avoid refined, sugar-filled junk foods.
