It is very good. Note it does say limit carbohydrate intake in a single meal or snack, not just eliminate high sugar foods, but it does pass over the point very quickly. My main gripe is that it uses the word sugar throughout rather than glucose, but I guess it does it for the interests of simplicity. Insulin is needed to allow only glucose to enter the cells: other sugars do not require it. The reason it concerns me is that I meet many people who think that as long as diabetics avoid sugar they are OK. By sugar they understand that white crystalline stuff (sucrose). So they will avoid cake made with sugar, but sugar free cake is fine. Fruits or fruit juices are fine because the contain fructose, not sugar, right? If people are given the wrong idea initially, will they ever progress to proper understanding. Obviously the illustrator did not know the difference between the liver and kidneys!
