Just to show how long this information has been around, in the following video Dr Jason Fung goes through the history of diets. This video is six years old so it shows how long he has been actively working with obese and diabetic patients. He has lots newer videos on YouTube.

It is a six part series but if you click on this link it will bring you to the first part and You Tube will pop up the rest of the series in the right hand column. It is pretty long, but it is kind of interesting about how the Standard American Diet and the food pyramid came about. Fung is the real deal. He doesn't sell foo foo juice and most of his recommendations cost nothing to implement. He has a clinic in Canada.

This is a long series but has a wealth of information about the body and the health thereof.

If you are diabetic, or pre-diabetic, are over weight, or just worry about becoming diabetic, the whole series IS VERY WORTH WATCHING.
