Is sugar free candy healthy to eat?

In moderation: Sugar Free does not mean free of calories, and sugar free candy generally is made with sugar alcohols. Sugar Alcohols are poorly and incompletely absorbed by the intestines, so eating a lot will give you bad gas and diarrhea. Taken in moderation, sugar free candy is better for your teeth than regular candy, and is a useful tool for diabetics and people on low carbohydrate diets.

Probably not: Sugar free candy is a way to get some of the joy and satisfaction that you might get from sugared candy, without the sugar and calories. It is a substtute for this and not a source of nutrition. So it is not "healthy' to eat but can satisfy the craving without the calories.

Yes and no.: If you eat a lot of candy, it might be better for you to avoid all the sugar. However, the artificial sweeteners in sugar-free candy aren't the healthiest ingredients either, being linked to fatigue and achiness. Your best bet would be to eat limited amounts, whichever you choose.
