Fruit juice: 26-29 grams of sugar
Whether it's a green smoothie or orange juice, fruit juice is loaded with sugar. You're much better off eating a piece of fruit instead of drinking juice. That way, you'll avoid added sugars and consume only fructose, a naturally-occurring sugar that's much more nutritious. Plus, the fiber in fruit will give you a feeling of fullness that juice won't.
