    In his book  (Quit plan) David shows the amount of fructose in nuts eg approx 1.3 grm in walnuts.   In the Australian & NZ Food standards guide, link below, walnuts do not have fructose, they do however, have sucrose.  In David's book he suggests that you halve the sugar content to work out the amount of fructose in the foods.  So in a walnut there is 2.7 grm sucrose, David appears to have halved this for the fructose, but there is no fructose.  In David's book he is stating  peanuts have  3.4 grm fructose in the guide below they have no fructose but sucrose 4.8 grm, halve this and it should be 2.4 grm.   I am a little confused.  Should I just halve the sugar content because I need to reduce the amount of sugar or is fructose the problem.

    Hi Diane,

    Food Standards website never used to show sucrose it always had glucose and fructose, it was only just last year or year before when they started showing all sugars as sucrose (not sure why they did that actually).  But basically when calculating something this is how you would do it.

    so walnuts have 2.7g of sucrose, no fructose and no glucose per 100g.  Sucrose is 50% glucose and 50% fructose to basically all you need to do is half the 2.7g. So in total walnuts have 1.35g of fructose.

    Ok something different, orange sweet potato (raw).   Sweet potato contain 1.2g fructose, 1.7g glucose and 2.7g sucrose.  Remember to half the sucrose, so that would be 1.35g plus the 1.2g fructose listed so in total that's 2.55g fructose per 100g.
