I wonder what the nutrient composition was for watermelons before they were transformed into giant sugar orbs.
The lowest sugar fruits are the berries - raspberries and strawberries are both ~4.5-5g sugar per 100g.
Watermelon is 6g/100g.
On the higher end, apples and oranges are both ~10g/100g, Bananas 12, and Grapes 16.
