Berries, citrus fruits, and cantaloupe are all low in sugar. Avocados have no sugar. Apples, grapes, and bananas have a higher sugar content by weight. Pay attention to serving size when comparing sugar content in fruit.
A healthy diet should contain about 2 cups of fruit a day. A half cup of dried fruit has about the same amount of sugar as one whole cup of whole fruit. Canned fruit usually adds sugar so check the nutrition labels and select ones with no or little added sugar.
That’s the way --- eat 2 cups of fruit a day!
