For a diabetic, this can be a bit of a nightmare - especially if you have to navigate your way around a large variety of candy that you may not typically eat.
Well, good news. The JDRF has a page that includes typical Halloween candy carb counts! This is fantastic for Type 1s so we know how much insulin to dose based on our carb to insulin ratios.
For any Type 2s, it can give you some guidance if you have a daily carb target, or just want to be aware of what you are eating.
You can find the page here.
