Are Alzheimer's and diabetes the same disease?

Interesting article on the links between diabetes II and dementia.  Apparently if you eat enough sugar and processed food you naturally forget all your troubles.  If that's your hope you have never watched someone suffer through the torments of Alzheimer's.  Sadly, I had to watch both my Grandmother and Mother suffer from this condition.   In some ways though, I think the toll it took on my father was equal.  Given the limited resources we have in the world and the mounting evidence regarding sugar and disease; what we put in our mouth is now as much of a moral problem as it is a health problem.  But we want simple quick fixes from our government to take care of our inability to exercise self-control.  Jean-Paul Sartre once proclaimed that France was more free during the German occupation than afterwards.  The occupation was a conscious reminder to the French people that we ultimately have no excuses for our actions, as human beings we are condemned to be free.  Of course, I guess you could keep sniveling about how you can't live without X or Y food, but I hope you have more dignity than that.
