According to Self.com, three high-sugar fruits are watermelon, bananas and oranges. Self.com recommends eating more fruit, but choosing options that are nutrient-packed with a lower sugar content. Also, it's better to choose fresh fruits instead of dried fruit, as dried fruit has more calories.

While watermelon contains potassium, vitamin C and lycopene, it also has a higher sugar content than other fruits. Self.com recommends opting for berries. Berries are a nutrient-dense superfood, and they offer all the benefits of watermelon, but with less sugar.

Bananas have a higher glycemic index than other fruits, coming in at 70, compared 18 for an apple. The body digests high-GI foods more rapidly than low-GI foods, which causes fluctuation in blood sugar levels. This causes spikes and crashes in blood sugar, which causes a person to feel hungry soon after eating a high-GI fruit or food. If a person needs quick fuel before exercising, a banana's energy-boosting potassium and fiber provides suitable sustenance.

Oranges are high in sugar, especially the juice. They are also very high in vitamin C. A better option for someone who is trying to avoid sugar is a grapefruit. An orange's GI is 50, compared to 25 for a grapefruit of the same size. The grapefruit also has fewer calories than an orange – 46 compared to 62.
