If you do a search on ANYTHING, you can find a study that "proves" something CAUSES a health problem, such as cancer, and another study "proving" that the same exact thing CURES it. To me, this PROVES that it's all rhetoric, and plain old common sense and moderation in all things is the answer.
Anybody remember the Great Hot Dog Panic of '76? Everybody threw out all their hot dogs, grocery stores and restaurants stopped selling them for awhile, and Dodger Stadium started selling hamburgers at games... All because some quack group of doctors said hot dogs cause cancer... Guaranteed and proven scientifically! But what they DIDN'T say, was the you'd have had to eat something like 85,000 lbs of hot dogs per hour for 10,000 years straight, or something like that, in order to match what their study used as benchmarks.
