Just so everyone knows. Most physicians get very very little nutritional training. Almost none. I know a recently graduated doctor who admitted they only taught ONE DAY of nutrition during her four years of med school. So: When you have questions about nutrition, or if your doctor tells you something that sounds odd to you about nutrition, just ignore it. They are not educated in the field, unless they have taken it upon themselves to learn what nutrition has to do with health. Trust me on this. Do some research. I suggest most people would do well to visit the Weston A. Price organization website and rove around.
