It sounds like you have type one and type two confused. Destruction of the beta cells (in the case of type two diabetes) can only result when a combination of these three things occur: prolonged exposure to high blood sugar from excessive carb intake, lack of essential nutrients to support healthy organs, and (most importantly) prescription of sulfonylureas which overwork an already overworked pancreas. If there’s one thing that gets my passion going, sulfonylureas is it. Once on them, you’re pretty much guaranteed to be on insulin shortly thereafter. We can argue until Jesus comes again about whether beta cells are lost over environmental or genetic factors. The point is, many of us (myself included) are genetically predisposed. Many of us (myself included) have actually improved our insulin output. How? Good question. Faith? Perhaps. Nutrition, exercise, reduced glycemic index diet? Most likely. Certainly, there are other factors, like toxins, but they are also avoidable, contrary to your belief (that would be a very healthy discussion for the two of us to engage in sometime in the future). All of these negative factors can be mitigated, or avoided completely, with simple diet, exercise, and lifestyle modifications (provided the disease is caught early enough). If you really and truly want to help people, you should be out there proclaiming the benefits of a super healthy, natural foods based diet and exercise instead of making it sound so gloomy. If I subscribed to your line of thinking, I’d be shooting insulin right now. Just like my dead mother, my dying brother, and all the rest of those poor souls who listened to their doctor instead of following their heart.
