There has been mounting evidence over the last five years that there is a connection between Alzheimer's and type 2 diabetes/insulin resistance. Researchers continue to figure out the details.
A July 16, 2009 article in Diabetes Health discussed other potential connections with Alzheimer's, type 2 diabetes including nitrates, nitrites and nitrosamines which are found in cured and preserved food, beer, fertlizers, pesticides and the manufacture of rubber products. Examples of cured food which are already known to exacerbate if not cause migraine headaches are: bacon, sausage, salami, some types of cheese, etc.
According to the article, "When nitrites combine with other nitrites or proteins, they become nitrosamines, which are highly reactive at the cellular level, altering gene expression or causing damage to DNA. One of the bases of nitrosamines is sodium nitrate, a chemical added to meat and fish to assist with a range of tasks, including preservation, color and flavor enhancement, and the prevention of toxins.
The high temperatures involved in frying or flame broiling generate nitrosamines from sodium nitrate, and the researchers think that they create changes in the cells that are much the same as the alterations that occur in aging or diabetes."
Also of note is that "nitrates and nitrites are chemical compounds that can be highly carcinogenic at high levels."
Though I can't imagine cutting bacon out of my diet ... what's better than good, crunchy bacon on Sunday morning? We all might be well-advised to moderate intake of such food and consider on a weekly basis "gee, what did I eat and how good or bad was it for me"? Did I eat 10% bad food or 75% bad food? Was it worth it?
I'm also not someone who can afford organic food but if fertilizer is a primary source of these chemicals, the more I harvest from my own chemical free garden the better. It makes me wish it were a larger garden and that I had a larger deep freezer!
