It is a double edged sword though, because a LOT of people, including many health-conscious people, think of fruit and fruit juices as equivalent when they very much are not. You can drink down 4-7 apples/oranges/etc worth of nutrient-rich sugar juice in a matter of minutes, with only a fraction (or effectively zero) fiber. Quite terrible for the kinds of insulin and leptin resistance, ATP disrupting effects discussed in the paper. It's also worth remembering that many types of modern fruits are extremely sugary and tend to be relatively less fibrous and nutrient dense than historical, wild, and heirloom varieties. "Eat whole fruits regularly and in moderation" is much better advice overall. Simple, to the point, and cuts out problematic ambiguities.
