Lactose and Dextrose

Here's an unusual question I received.

After I got very ill I again looked at the ingredients and spotted dextrose. Are they similar and do you get others who have to also avoid too much dextrose?

Both lactose and dextrose are sugars but the resemblance stops there. Dextrose is in fact another name for glucose. Glucose is not only one of the sugars you get if you properly digest lactose, but it is the body's basic energy source. All sugars and carbohydrates break down to glucose, or another sugar that gets converted to glucose. You need it to keep your body going.

So nobody ever gets symptoms from glucose. If glucose bothered you, you'd be dead before you got a chance to check the ingredients list.
