Cordial Deconstruction

Observations from our shared single objective reality in a materialistic, naturalistic, & effectively macro-deterministic universe.

Zicam Increases Risk of Iocaine Poisoning!

Posted by Karl Withakay on June 18, 2009

The FDA has issued a warning that using Zicam can lead to anosmia, which is a loss of the sense of smell.  Many bloggers in the blogosphere (pretty much most of the sites in my Daily Sites links) have covered this already, but they have all ignored the most serious potential risk of anosmi from taking Zicam: Iocaine Powder poisoning

As we all know, the best way to detect Iocaine Powder is from its lack of scent, but if you can’t smell anything at all, how will you know if something doesn’t have a scent (or has no added scent) since everything lacks a scent to you?

Of course the Iocaine poisoning risk would be greatest for people in Australia and people going up against Sicilians when death is on the line.

Rumor has it that land wars in Asia will be unaffected.

I felt that this risk needed to be brought to people’s attention.

That is all.  🙂

Deconstruction: 5 Secrets to Preserve Your Eyesight

Posted by Karl Withakay on June 15, 2009

OK, finally, an actual Deconstruction.  Deconstructing various Yahoo features will probably be a semi-regular feature of my blog, for as long as I actively maintain the thing.

Yahoo’s main page frequently features various “health” articles of somewhat dubious value, and now I finally have a blog on which to deconstruct one.

Today I saw the story, 5 Secrets to Preserve Your Eyesight (warning for the right-click impaired, the link opens in the same window), and decided to take a look.

It’s pretty typical fare for the types of “health” articles Yahoo features, providing a lot of sciencey sounding, but unsupported recommendations, appeals to ancient wisdom, and repeating one or more already debunked medical myths.

The first particular I’ll address is the first “secret”

1. A juice to brighten your eyesight
An age-old Chinese folk remedy for clearing the vision is a blended juice made from celery, peppermint, and Chinese parsley. Research has caught up with this wisdom, and we now know that luteolin, an antioxidant bioflavonoid found in these three ingredients, has been found to provide the best protection of cell DNA from radiation. Some evidence shows that luteolin helps protect the eye from UV radiation damage, as well as from glycation, a process in which sticky sugar molecules bind up protein, potentially damaging the retina. Luteolin also promotes healthy blood sugar levels and regulates insulin sensitivity. Blend together celery, peppermint, and Chinese parsley in a blender with a little water or a juicer. Drink this fresh juice daily to see well into the future!

First, I’ll just address that the article provides no references to support the claims made in any way; we’re just supposed to accept that the author speaks with authority.  It may be unrealistic to expect support references, but at least a passing mention of the source of the research and evidence would be nice, as in “research at XYZ University in 2001  showed….”.

Next, notice how the article doesn’t say that  these ingredients have been “shown to provide the best protection of cell DNA from radiation”, “protect the eye from UV radiation damage, as well as from glycation”, or “promotes healthy blood sugar levels and regulates insulin sensitivity”, only that substances found in these ingredients have.  In my experience, this is fairly typical of mainstream media “health reporting” in general.

The reasoning goes something like this:  Item A has been shown to have health benefit Y.  Item B contains item A, therefore item B has health beneift Y.  This is fallacious logic.  There are numerous reasons why item B may not have health benefit Y.  Item B may or may not contain sufficient amount of item A, it may contain item A in a different (less effective or ineffective) form, or item B may contain other ingredients that offset or nullify the beneficial effects of item A.

If item A has been shown to have health benefit Y, and item B contains item A, we can say there is reason to investigate item B to see if it too has benefit Y, but that’s about it.

Item 2 “Eat for Eye Health” is essentially a bunch of unsupported claims which may or may not be true.   I don’t feel like taking the time to research them to see if they hold any merit (It’s my first real Deconstruction, give me a break).

Item 3, “Stay hydrated” parrots the debunked notice of needing to drink 8 glasses of water a day (even the CDC still parrots that one, so it’s hard to blame the author too much for it) and adds that proper hydration is essential for good eye function.  It’s of course important to not become dehydrated, but most people’s current liquid intake is already fine.

Item 4, “Eye exercises to fight floaters“: I spent a few minutes searching the internet, and found no scientific support for these claims.  I did find info on the Mayo Clinic’s site describing the causes and treatment of floaters, but strangely never found any of these exercise listed.  Wearing of UV-protective sunglasses is something my eye doctors have been recommending for decades, so I’m OK with that advice.

Item 5, “Instant eye remedies“: is mostly unproven, scienced up herbal remedies, but the recommendation for eye exams is reasonable.

As we get to the end of the article, surprise-surprise, we find that the author, one Dr Mao, has a book he wants you to buy, and he also sells “natural health products”  on the Tao of Wellness website.

Dr Mao’s website states that he  “is a doctor of Chinese medicine and an authority in the field of Anti-Aging Medicine” and “has two doctorate degrees and wrote his Ph.D. dissertation on nutrition”  It does not say what institutions he has his doctorates from, and it although it says his dissertation was on nutrition, it does not state that either of his degrees are in nutrition.  He is most clearly not an MD, and this is something which is not at all clear in the Yahoo article.

I get the feeling that people like Dr Mao really want us to actually use only 10% of our brains, and not think critically when consuming information.
