A study in the June 2013 issue of "American Journal of Clinical Nutrition" found eating your daily five of fruits and veggies could lead to a longer life span. McDonald's smoothies contain fruit puree, fruit juice and low-fat yogurt, making them one option for getting some of your daily fruit servings. Depending on the size and flavor, the smoothies average between 220 and 340 calories.

Watch the Sugar
You should examine the other nutritional facts of McDonald's smoothies before deciding if they are a worthy expenditure of your daily calories. Smoothies are low in sodium, but high in sugar. Depending on which size you choose, a McDonald's fruit smoothie has from 44 to 74 grams of sugar, which translates to 11 to 18 teaspoons. The American Heart Association recommends limiting sugar intake to 6 teaspoons daily for women or 9 daily for men.
