Eating too many fruits can provide too much sugar, but fresh fruits have low sugar content in comparison with any artificial sweet food.
Only dried fruits, like raisins, dried figs, dried dates, dried prunes and so on, have high sugar content, well over 50%, so they are comparable with chocolate or candy bars.
Most fresh fruits contain only around 10% sugar, with a only a few, like grapes or fresh figs exceeding 15% of sugar (but less than 20%).
This means that for most fresh fruits you can eat a half kilogram (or a pound) per day, while still avoiding an excessive sugar intake.
