$this->bbcode_second_pass_quote('', 'T')he fundamental problem is that it doesn't work. Back in the 70's we were all supposed to switch to this low fat diet and it was going to wipe out heart disease within a decade. Since then we've been sitting around twiddling our thumbs. "Ok. We made the switch. When is this going to start working?" Meanwhile we're getting sicker and sicker.
Yes, I know, the War on Drugs and the War on Cancer were declared around the same time, too. Neither wars are over, and neither have made any significant difference to the number of drug addicts/users or the drug trade, or the number of cancer sufferers. It's not hard to foresee a similar outcome for the more recent War on Terror ....
I think the conclusion that the low fat fad has failed, doesn't take into consideration the overall
increase in caloric consumption throughout the campaign coming from ... what exactly? larger portions, higher levels of hydrogenated fats, the use of corn and starch sugars, palm oil and certainly an increase in processed foods generally, not to mention those gallons size soft drinks Europeans are always surprised to see in the hands of Americans. Okay, they may be no sugar, but what ever they contain to replace the sugar is certainly no healthier.
You know as well as I do the bottom line in weight loss is lower caloric consumption. Fewer calories in, and more expended, and you've got weight loss. Whether you're eating grass or an animal that ate grass.
My point is that you can not take a single dietary component and study it out of context, and expect to get reliable or usefull results. There is simply too much going on in the body to blame specifically one item or another for ill health, and likewise to tout one ingredient over another as being a 'health promoter'. This, to my mind, is why the subject of nutrition and health is so confused and confusing: we don't know everything about how the stuff we put in our mouths works synergistically. And to make matters worse, of course there is an
industry involved with, or behind just about everything we can eat, or simply a life style to promote for profit/fame etc. (i.e The Atkin's diet) and so the information we get is practically ALL skewed one way or another by the time it reaches us.
An example of the confusion is the whole Omega-3 fad: most people don't know we actually
need Omega-6 and 9 as well, (there's a hint in the name
essential fatty acids,) but the message which has come across is basically
stop eating bad fats!
I think Campbell's book
title is perhaps misleading, since it includes far more scientific studies than just the one China Study which serves as the title. His conclusions are certainly not drawn from just this one study, which as critics have rightly pointed out, takes up a very small portion of the whole book. But you'd have to make up your own mind about that from reading the book, and seeing for yourself the science he refers to, to support his conclusions.
In any case, the public confusion over what to eat and what not to eat doesn't seem to be close to resolving any time soon, and arguments such as Taube versus Ornish don't help matters.
As for the being hungry because of having more kids, I have to agree, but I still think you'd agree that this particular problem is a lot more complex than just the 'it's in their culture' excuse.
