“I have another article to post about salt and diabetics. Again I say, every day something comes along to dispute what “everybody knew” the day before.”
That’s because statistical analysis and ‘outcomes research’ is not accurate enough to base medical practice upon. It is absolutely not evidence-based medicine, as proponents would have you believe. Large database studies are fraught with error, and the people who do them know that you have a better chance of getting published if you show something that is contrary to accepted practice, or if you show data that suggests that minorities or women are treated differently. It’s sad.
I am becoming more and more skeptical of all scientific studies. You would probably enjoy the books by Dr. Nortin Hadler, Worried Sick, and The Last Well Person. Your local library may have both.
