Low-sugar fruits include avocados and berries such as raspberries, blackberries and strawberries. These fruits are not only packed with nutrients but are also appropriate for low-carb diets.
Weighing sugar content against other nutritional benefits is a good way to choose the healthiest fruit to include in a daily diet. As a group, berries are among the best all-around nutritional bargains. Raspberries contain little sugar but a lot of fiber, while cranberries and strawberries are low-sugar and high in vitamin C. Blackberries have only a little more sugar per serving than raspberries, making them a good choice for smoothies and snacking.
Avocados are packed with healthy fats, making them an especially beneficial food. Rhubarb is also low in sugar, as are small servings of lemon, lime and grapefruit. Fruits with moderate levels of sugar include apples, apricots, blueberries, papaya, peaches, nectarines and melons, including watermelon, cantaloupe and honeydew. At the other end of the scale, fruits that are high in sugar include oranges and tangerines, bananas, grapes and figs.
As a rule, to gain the most benefit from a fruit while consuming as little sugar as possible, it's best to eat the fruit in fresh, raw form rather than cooked, dried or juiced.
