Good news: A little sugar can go a long way.

Adding a wee bit of sugar to balance a too-tart tomato sauce is a good thing; so is a teaspoon of honey on a tart grapefruit half or in plain yogurt. “Add a little bit of sugar to help boost your intake of nutrient-rich foods by making them tastier,” says Jackie Newgent, RD, author of the All-Natural Diabetes Cookbook.

In this refreshing palate cleansing sorbet, sugar tames the tartness of grapefruit juice. And with just two ingredients, it could not be simpler to prepare. A serving delivers about two-thirds of your RDA for vitamin C, and only 145 calories.
