7. Pears
Pears are high in both sorbitol and fructose sugar, a double whammy for sensitive stomachs. Pear juice is even worse, with almost as much fructose as in sodas sweetened with high fructose corn syrup.
Too much pear can cause all the bloating, cramping, and diarrhea that comes with other high-sorbitol fruits, as well as pack on the pounds. Pears have about 10.5 g of sugars per 100 g serving, but a whopping 6.4 grams of that is fructose.
