I'm sorry, I don't wait for science to make a statement in order to take common sense seriously.
For example, doctors are still telling people to limit their calcium intake when they get kidney stones, even though this has been shown to cause more kidney stones. I knew this before the doctors. Why? Because everyone I ever knew who said they had a kidney stone said to me "it's funny, because the doctor said I should start drinking less milk, and I had already cut down on the amount I drink recently." Did I know the causitive factor? No. However, I did have enough common sense to see the pattern.
Of course, today, even after the studies have shown the _lack_ of calcium to be a prime factor in kidney stones, doctors _still_ recommend patients reduce their calcium intake to avoid stones.
Grrrrr....
