My favorite kind of passage in an article about science is this one, in the Guardian's article, Alzheimer's could be the most catastrophic impact of junk food:
New Scientist carried this story on its cover on 1 September; since then I've been sitting in the library, trying to discover whether it stands up. I've now read dozens of papers on the subject, testing my cognitive powers to the limit as I've tried to get to grips with brain chemistry. Though the story is by no means complete, the evidence so far is compelling.
I'm less unambiguously enthused about the premise of the article: that Alzheimer's Disease might actually be a form of diabetes. According to diabetes.co.uk, which outright refers to Alzheimer's as Type 3 Diabetes, "many type 2 diabetics have deposits of a protein in their pancreas which is similar to the protein deposits found in the brain tissue of Alzheimer's sufferers."
This scares the crap out of me, because Alzheimer's is one of my biggest looming fears,[1. As opposed to non-looming fears, like spiders, car accidents and being alone in the dark.] and I don't exactly have a fantastic diet. I'm pretty sure I'm safe for Type 1 Diabetes, but my family has a history of Type 2, a fact I know because my mother pointed it out to me every few weeks/months since middle school, which is why Type 2 Diabetes is another one of my big looming fears.
On the bright side, though I find it difficult to improve my eating and exercise habits for reasons like "I'll probably be healthier and live longer and stuff," imagining a future in which my mind slowly degrades to the point where I become a burden and a constant reminder of a lost person to the people I love, while I'm trapped knowing that I will never again think the way I used to, is sufficiently terrifying that it might stop me eating pop tarts so often.
Although, if climate change is any indication, fear of ensured doom is a terrible way to motivate humans to change for the better.
