Re: These include chocolate, of which Australians "eat the equivalent of 32kg" per year.
> "eat the equivalent of 32kg of chocolate" is 16Kg. Apples are 10%
Apples contain a good bit more than that - but it isn't generally available. The sugar in chocolate is generally sucrose which is only one step from glucose and easily converted so your blood sugar levels tend to look like the north face of the Eiger..
Apples OTOH, have a lot of their sugars as fructose and locked up within nice cellulose packages that your gut has to work harder to open. So your blood sugar rise looks more like a small roundabout in profile and the broken insulin feedback system has more time to adjust.
Also, Apples contain citric acid and acidic things seem to also slow down sugar take-up (dunno why!).
 Which is why drinking sweet fruit juices is generally not a good idea for t2 diabetics - all the sugar is now in solution and much much easier to absorb. Even things like rhubarb juice contain a suprising amount of sugar..
