Again this is nothing new.  Yes the low GI diet is healthier in
relation to a high GI diet.  That is what this study shows.  You are
doing exactly what you accuse others of doing by saying this study
proves something it does not.  The study does not provide "clear
support" for including whole complex carbs in a mixed diet.  It gives
support to a low GI diet over a high GI diet.  Hardly ground breaking.
Why dont you admit that you view things with just as much bias and
preconceived notions as the others who you accuse of the same thing.
And while you are at it you can thank me for pointing this out to you
so you can avoid such things in the future.

What is funny about this study is it shows directly that high GI diets
lead to risk factors for heart disease and diabetes.  Risk factors
they have previously blamed on fats(especially saturated fat).  Fat
was not even a factor in this study.  They unwittingly added yet more
evidence against their preconceived ideas and false theories like the
lipid hypothesis.  Despite this they do not even consider the reality
of what they have observed and what significance and impact it has on
those previous assumptions.  Anyone who looks at this rationally and
unbiasedly can understand such significance.  One can easily see that
while fat was not a factor in the increased risks of disease in this
study GI has always been an uncontrolled, unconsidered factor in
previous studies that blamed saturated fat.  Could this possibly be
why there is so little relation between cholesterol and fat to
disease.  Could this be why their observations are always so
inconsistent?  Maybe if they designed real studies that could reveal
deeper truths they would learn something.  That would be real science
as it is done in most other scientific fields.
