The Alzheimer's link is a relatively new one (at least in the media) and looks to be a little bit of sensationalism: it sounds scary, makes for a good story and there's plenty of ways to angle it.

Pragmatically, there's little downside to publishing it as well - if people eat healthier and exercise a little more as a result, brilliant. For researchers given the wide base of ground to cover in the disease, if it gives more funding in their fields, also brilliant.

Taking a step back and looking at Alzheimer's just as a metabolic disease (which does have some merit, let me find the papers) does give some new avenues to explore. Same as you will be interested to see what comes out of it. It truly is a crushing disease for all involved.
