OK I've been on fructose for many years, as a type 1 it does gently raise sugar levels but no more than no sugar marmalade or bananas.
Alot of the USA discussion appears to be related to those that aren't diabetic so I don't get there argument. The idea you'll eat more cause it's not satisfying is rubbish.
I have eaten fructose in cakes (gluten free too

) and know one knows any different.
It's a great replacement, I use it in tea rather than the chemical replacements.
Health wise, I've low good blood pressure, fit, not over weight and relatively healthy with good long term sugar level count around 6/7 ish.
I cannot see why people don't try it for themselves rather than listen to self interested marketing talk. If sugar levels are good, no weight gain and tastes good what's not too like. Unless it causes cancer or damages kidneys and liver then what'd the problem. If it doesn't suit your digestion then fair enough.
It's great for baking just use a lot less, no saccharine taste, good in tea and if I weren't diabetic I would use sugar I'd use the fructose sugar instead.
Good luck with it if I make it to 70 yrs I'll be happy. Good blood sugar and sweet taste - all good.
