If you want to limit your sugar consumption, but you're still a bit of a sweet tooth, you can easily give the sugar in fruit more sweetness.
Sprinkle a pinch of salt on your fruit salad, and they will taste much sweeter by themselves.
That 'pinch' won't hurt your blood pressure. Adding salt will make your tongue much more sensitive to the sugars in the fruit. So it seems that your fruit is sweeter.
