I've bought Gallop's The GI Diet: The Easy, Healthy Way to Permanent Weight Loss and Living the GI Diet: To Maintain Healthy, Permanent Weight Loss. I also bought The GI Diet Pocket Book for my wife's handbag when she goes food shopping :shock: Seriously though, the pocket book has a handy guide to eating out as well. If you like I can PM you the Amazon links to the books.
As for snacks, Gallop suggests that you can eat as much low GI foodstuff as you want, there are a few exceptions to this rule (Bread, Cereals, Nuts, Margerine, Meat, Fish, Poultry, Olive/Rapeseed oil, Olives, Pasta, Potatoes (boiled new), Rice, Crispbreads).
As for prolonged exposure to stress causing diabetes, there is no evidence that stress directly causes diabetes. Having said that, in the eighteen months leading up to my diagnosis I was experiencing high levels of stress, as a result my lifestyle was not the best, so there could very well be an indirect causal link.
