Alzheimer's and BasicH2

I was recently told about a "home remedy" that really took me by surprise. Coconut oil can be used as a treatment for Alzheimer's.
My friend Lloyd had gone through a long battle with his father's Alzheimer's before we knew as much as we know about it now. It is a tragic story about how no matter what treatments were given it seemed like a losing battle. Now that we live in an information age, it's easier to learn about alternative medicines and treatments. Lloyd was told about coconut oil as an alternative treatment, and since then him and his wife have been cooking with it to try and use it as a preventative measure.
Where my thoughts on the whole thing came from was from a highly disputed article I read some time ago from the medical journal Evolution, Medicine and Public Health. This lay summary of this article states:

Lay summary: People living in sanitized environments may be at greater Alzheimer’s
risk. We compare Alzheimer’s rates in different countries in light of countries’ historical
and contemporary pathogen prevalence, sanitation, and urbanization. We find that
countries that are less urbanized, with more pathogens and lower degree of sanitation
have lower Alzheimer’s rates.

My opinion on this wasn't that clean people are more susceptible to Alzheimer's, it was that I immediately thought of the air quality issue. Clean people use more household cleaners, plus being in a more urban area there is more commercial and industrial pollution.
So what is the best way to combat this? In my opinion the best way you can help the quality of life in your own home is to use a natural cleaner. Shaklee's Basic H2 is all natural. It's non toxic. It's made out of (the above mentioned) coconut...
Wouldn't you rather be breathing in something all natural than all of the chemicals in every store bought cleaner?
