Re: SkinSterols predict metabolic syndrome

[Guest guest]

Hi folks:

Not ONLY to be the devil's advocate here ........... but the first

thing to come to mind for me about this study is to ask whether they

made sure they were not failing to distinguish the horse from the

cart. Perhaps they did not have this problem, but may not the horse

be the waist circumference? And everything else the cart?

And by that I mean that I would not be at all surprised to find that

all their other data, including their skin test and hsCRP, are simply

a function of the degree of obesity. In which case this study would

not be adding any new information beyond the fact that the skin test

is ALSO correlated with all the other data that we all here know

result from obesity, the cause of metabolic syndrome.

If we saw the full study we might be able to resolve this question.

Perhaps on the weekend I will look for it. Or email the author and

ask the question. (He will not like the question so I probably will

not get an answer. But no answer sometimes is all one needs in a

case like this).

If anyone has the full text of the study and sends it to me, I

promise to read it from end to end and comment on it next week.
