Yes, and it's odd. Basically if you have CRC you are 35 percent less likely to get Alzheimer's; conversely, if you have Alzheimer's you are less likely to get cancer (by half). And it is apparently the result of which microbes you have in your intestinal system. All of which sounds like my grandmother's insistence on curing us with chicken soup. On the other hand, she also thought the less you moved, the longer you would live, because you weren't using up your energy.
I'm glad to see Science is finally listening to my grandmother. It's about time.
