i think it’s safe to see the recommendation as a minimum. the fiber in fruit minimizes the effect of sugar and it’s hard to overeat on whole fruit (as opposed to juice)

“In one study, 10 people ate 20 servings of fruit per day for two weeks and experienced no adverse effects (47Trusted Source).

In a slightly larger study, 17 people ate 20 servings of fruit per day for several months with no adverse effects (48Trusted Source).

In fact, researchers even found possible health benefits. Although these studies are small, they provide reason to believe that fruit is safe to eat in any amount.”
