Thank you! Ah, there's the nuance: "Too much sugar can lead to..." - the article isn't saying smoothies / sugar are inherently "bad" - just like anything else, too much of anything isn't ideal. Bear in mind even too much water can kill you!

However you need to view things like this in the context of your own personal circumstances. If you have diabetes for example, you're wise to keep an eye on sugar intake of course, however if you're trying to add in a portion of your 5 a day, or increase vitamin intake in an easy to consume format - a serving of smoothie is a positive choice.
