the drug people think is not a drug

sugar Refined sugar is so much like the human body's internal sugar that it enters the blood stream too fast. This gives you a high followed by a low as the body attempts to compensate for the overload. Repeated hits of sugar take their toll over the years.

It was about 1982 when I first read "Sugar Blues" and, after reading quite a few other books on the subject, I still recommend it highly.
