Bananas, certain melons and "stone fruits" contain high levels of fructose.
While there have been studies conducted to determine the effects of fruits to people with diabetes, there are still some questions regarding what fruits should be considered as good or bad for diabetics. Fruits are recommended to diabetics because they are considered a great source for vitamins and fiber. But, when they are fruits like bananas and certain melons, and stone fruits like nectarines, peaches, plums, apricots and cherries, contain high levels of fructose which can be detrimental for diabetics.
Because these fruits contain these levels of fructose, it can cause high spikes in blood sugar content. However, this may not be the same for everyone. To be safe, it is recommended to avoid these when patients can and try to find options that include fiber and essential vitamins.
Try these fruits instead
Just because some fruits are bad doesn't mean that others should be avoided. Doctors recommend that diabetics should eat Granny Smith apples, blueberries and berries that have a low sugar content. But, when choosing fruit for you, you must know for yourself what works. Some fruits do better to provide the essential vitamins and fiber. The best way to determine this is to test your blood sugar after two hours of eating a certain fruit to see how your body reacts. If it's a good reaction, keep eating it! If not, stay away from it.
