Eating a nutritious breakfast has tremendous physical and mental benefits. According to MayoClinic.com dietitian Katherine Zeratsky, having a healthy breakfast can boost your energy level, encourage you to be more physically active, help curb snacking and overeating and aid weight maintenance and weight loss. "Cooking Light" magazine states that the most nutritious breakfasts have a combination of healthy fat, fiber-rich carbohydrates and lean protein.

Fruits are the stars of any healthy fruit smoothie. According to MyPyramid.gov, eating more fresh or frozen fruits can reduce your risk of stroke, heart disease, kidney stones, bone loss, diabetes and cancer. Avoid fruit juice, which often contains preservatives and added sugar. To get some healthy fat in your smoothie, try adding a swirl of flaxseed oil, a spoonful of unsweetened cocoa powder or a tablespoon of nut butter. Low-fat protein is also important; the healthiest choices include nonfat Greek yogurt, skim milk and soy milk.
