Maybe an online free book isn't the best thing to look for, unless you take your computer to the market. Why not get a very small, fits in your pocket, book on the glycemic loads of foods? A good one is The Easy GL Diet Handbook by Dr Fedon Alexander Lindberg. U.S. $10
Personally, I think saving my health and life is worth $10
What's the worst thing to eat if diabetic? - all dried fruits and all grains!
Glycemic loads in this book - 0-9 low 10-19 medium
foods over 20 are high glycemic load and you really need to avoid these if diabetic.
