GI diet - does it work and how can I find out what the GI index of food is?

[GIJane]

I got this book free with Slimming Magazine yesterday and it all sounds fairly straightforward, but it only listed the GI value of a few foods. How do I find out the GI value of all foods?

there is a web site that lists the GI values saw it ages ago and have since lost it! Have a google there are loads of sites on it... it does seem to work for me -- but I don't have a sweet tooth - imagine it is hell if youhave!!
