Question:

I've noticed that a lot of the sweets I buy in the health food store are sweetened with fruit juice, honey or something called fructose? Are these better for me than sugar? — K.Lehman, NY

Anne Coulston

Answer:

 

Yes and no. All carbohydrates, whether the source is sucrose, fruit juice or honey are converted through digestion and metabolism to glucose, the sugar that travels in the blood stream and provides necessary energy for all our body cells.

Fructose is a carbohydrate that is metabolized differently in the body than glucose, but it can be converted to glucose by the liver when it is needed for energy. Fructose can also contribute to the synthesis of fats for energy storage. Sugar, or sucrose is a refined carbohydrate and is purely glucose and fructose when metabolized.

Fruit juice and honey contain trace amounts of vitamins and minerals that contribute to overall health. However, since they are usually used in addition to other sweeteners, the amount of fruit juice and honey that are in a product won’t likely provide any meaningful amount of nutrients to the diet.
