Fascinating study.... but I feel sorry that monkeys also get DM... as well as intrigued... what does this mean? I mean after all, they must eat very little of the highly processed food some attribute causative effects to. Hmmm.... 8)
Does this support the conjecture that DM is in large part of genetic origin?

Some points:
Among a colony of rhesus monkeys tracked for more than 20 years, animals whose calories were restricted to 30% below normal lived no longer, on average, than monkeys whose eating was unrestricted, scientists found. But the diet did offer clear benefits, notably in warding off cancer.

Among the younger animals, the scientists didn't find any survival edge for dieting animals. But they did find reduced rates of diabetes and stark differences in cancer rates.

The Wisconsin diet consisted of purified ingredients mixed together and was high in sugar, perhaps explaining why so many of the free-feeding monkeys in that study developed diabetes. The Maryland monkeys ate a diet made from natural ingredients that contained more plant micronutrients and omega-3 fatty acids, among other items.

Makes me wonder about something else:

If the dieting monkeys had a lower risk of diabetes, heart attack, and cancer, yet still had the same life expectancy, then what killed them more often than the well-fed monkeys to make up for the difference?
