A couple of observations, obtuse as they may be ... incongruent?

A) information overload.
One day coffee is bad then next day coffee will protect you from Alzheimers and cancer.... eventually people say screw it.
B) ignorance of the public. A report on CNN or web of some quack is treated at the same level as real researched and supported info.
C) research by definition does hardly ever claim 100 % effectiveness, the quacks do
D) money, something that does not cost a mint cannot be worth much. Plus who is pushing this? Also there is not much money in it for the MD's.. although there ARE those who push this now. (May I point to US hysterectomies.... )
E) Even if you have a decent scientific background it is difficult.. (Se, Vit D, E, kinase inhibitors, etc). Plus a lot of stuff makes sense in a narrow application (i.e. hyperthermic theapies etc).
F) did I say B....
G) Political considerations... Gardasil. Also, as a physician you can get in trouble if you tell a patient that they are overweight.
... This is a fact (in GA).
I) We need a place where you get spin free info ... besides OCF. NIH might (should?) be the place......

... and I am off the soap box....
