In the original journal article they are grouping 'soft drinks, fruit drinks and fruit juices' together so I think it's tough to take any lessons about juice specifically from this study

I guess we're talking about diet and what health claims are accurate ? And people often act like juice is good for you but most of the benefits of eating fruit is in the fibre idk I don't think it's so outrageous to talk about it

But do they mean juice that's made at home or the kind of stuff you get that has loads of additives and preservatives like Sunny D? To be honest, even juice that's made like in the picture and doesn't contain the fiber of the fruit isn't really that good for you.
