In moderate quantities, fructose cannot be harmful.

Nevertheless, with easy access to concentrated forms, like sugar, but also honey and dried fruits, it has become possible to eat too much fructose per day, which is guaranteed to have bad health effects, like damaging the liver.

The recommendation that I have seen is to eat up to 50 g/day of sugar, i.e. up to 25 g/day of fructose.

When eating only fresh or defrosted fruits, it is easy to follow this, because the upper limit corresponds with around 500 g of most cultivated fruits or with around 300 g of the sweetest fruits, like grapes or fresh figs.

On the other hand, a single chocolate may contain more than 60 g of sugar.
