I used to be addicted to sulphite-free dried mango, dates and other sulphite-free dried fruits. I thought I was doing OK by avoiding the sulphite, as others recommended, but that turned out to be bogus advice for me. Even sulphite-free dried fruits caused me major problems. I didn't realize it until I cut them out. I'm more carb sensitive than most people, so your experience may differ. The only way you can find out is to test it for yourself. No one else can know what your experience will be.
BTW, I discovered that not only were fresh papaya and fresh figs less of a problem for me than dried, though I do have to limit my intake, but they actually taste WAY better to me than the dried versions. And like GS said, fresh mango is also tasty, so why not eat it fresh (or as fresh as you can get in your area, that is)? My guess is that tropical fruits are probably healthier to eat when they are taken right from the tree (tree-ripened) in the tropical nations where they are grown. It might be best to eat more of the fruits that are native to your region and truly fresh. Just a guess.
If you must eat dried fruit, then why not try drying it yourself, with no added heat (air-drying), or at least as little heat as possible? My guess is that dried-fruit manufacturers probably use rather high temps to quicken the process.
