Fruit juices maybe. Smoothies are a much more complex issue. I make my own smoothies, 3 or 4 a week. I know what goes in there. I put 1, sometimes 2 cups of fruit or berries. No added sugar, no fruit mixes, no "smoothie mix" stuff. I also add Greek Yogurt, protein, and all sorts of other mostly glycemic-neutral items. I've also seen pre-canned and restaurant smoothies that I wouldn't touch with a ten-foot pole. Some of these things are sugar bombs. Incredible amount of glycemic impact. You'd be better off just getting a milkshake. But for me, two cups of fruit a day is not a significant health risk at all. While I completely agree that fruit juice and smoothie consumption can be just another sugary alternative to soft drinks, they don't have to be. Unlike store bought fruit juices and soft drinks, with smoothies the entire purpose is that the drinker is in control over exactly what they're consuming.
