What fat is doing to people's bodies is bad enough. But I am seeing more and more studies that suggest there's a correlation between diets heavy in processed and highly processed "food product" and dementias, including alzheimer's . Imagine a world in which pretty much everyone is fat, and those that make it to 50-60 are doomed to developing dementia. That's what terrifies me : Losing a mind is way worse than losing a foot  (though neither is good , especially if it's due to preventable causes, like not eating crap that's pretty much literal poison).
