Okay, first off, no one knows if feeding sugars or starches (or certain types of sugars or starches) can increase the risk of insulinoma, but the hypothesis DOES has some reasoning behind it, and it is possible. Some foods are major no-nos because they have a documented history of causing blockages and thus requiring emergency surgeries or causing deaths. Among these are: carrots (esp. raw), broccoli stems, some types of dried bananas, and any other food that is hard, thick, and difficult for ferrets to digest. WE are descended from primates that were mainly eaters of vegetables, fruits and insects for tens of millions of years, and in the non-industrial state meat still makes up a minor portion of the diet. (Yes, people in the more of the ancestral state are gather-hunters (3:1) instead of hunter-gathers (25% vs. 75% of diet) if a person is going to be accurate.) We also have a diurnal history for a long time. FERRETS are descended from animals that were obligate carnivores for tens of millions of years. They are descended from burrow dwelling (DARK) crepuscular (dawn and dusk) hunters. What is healthy for them is not healthy for us; what is most healthy for us is not healthy for them. They need way more animal food (and not just meat since a muscle-only diet has nutrient shortages) and they need way more true darkness. BTW, even humans aren't made for the amount of sweets that are in the modern industrial society diets. That said, we give some raisins (though NOT many), and some Nutrical, and if one gets a UTI then we include some dried cranberries from a place in Michigan for the tannins, and we do get ferrets with some insulinomae, but only very few over a span of 19 years, and have had only one die of insulinoma so far since surgery has been marvelously successful for our crew. Have one elderly one now who is not a surgical candidate due to almost dying in two previous surgeries for a chronic problem of her's and she may wind up passing eventually of her insulinoma. Then again, we don't give sucrose laden starchy treats like Cheerios (though Glueball steals those against our wishes at times). One of the things that sets our guys apart from too many others is that they get a LOT of exercise. It really seems to keep them healthier -- a lot healthier. They also have night covers, and very, very dark nap places since we are in a tiny place and can't provide a black-out room for them for the long spaces of time that would better simulate how many hours their wild ancestors got. Might these things help. Yes, they might. Then again, a home sample simply is too small to know, there is a dearth of actual studies, and surveys simply have too many inherent sampling and reporting errors to be trust-worthy. All that folks can do is to learn what hard info is available, and to then try their best, understanding that some of it is simply guess-work. [Posted in FML issue 3601]
