There has been much discussion over the years about fruit sugar and whether it is helpful or harmful as a part of a healthy diet. Many recent low-carbohydrate diets prohibit fruits, claiming that they are too high in sugar. Other diets incorporate fruits as a main staple. Though for some people with diabetes and other blood-sugar related illnesses, too much of any sugar can be problematic, most people will benefit from eating fruit on a daily basis. It is easy to digest and offers a quick source of energy. Fruit also provides fiber, vital nutrients and antioxidants.


Fructose, a monosaccaride, is the most water-soluble of all sugars. It is found in fruits, honey and some root vegetables. Its water-solubility makes it quick and easy to digest. Fructose is low on the glycemic index (a measure of the effects of carbohydrates on blood sugar levels) as compared to refined table sugar. Fructose can be purchased in a crystalline form and used as a substitute for refined cane sugar, though should be used in moderation (just as with any processed sugar.)


Glucose is another monosaccaride and is stored with fructose in fruits. Upon digestion, it is delivered to the cells of the body to provide energy, or is stored to be used later. All carbohydrates are broken down into glucose. It is the source of energy for our brain and red blood cells.


Sucrose is a disaccharide, meaning that two molecules are bonded together, in this case, fructose and glucose. Sucrose is the sugar most commonly used in the form of cane or beet sugar, in a crystalline form. Fruits contain a wide range of sucrose levels, which should be considered when intentionally cutting back on sugars, in general.

Fruit Sugar Misconceptions

According to the American Diabetes Association, fruit is a healthy part of a balanced diet. It is not a contributor to diabetes, nor does it cause weight gain, when eaten in moderation. Fruit has been known to restore wellness, improve digestion and increase overall health when combined with a healthy lifestyle including exercise.
