The Guardian has the article The sugar conspiracy.

In 1972, a British scientist sounded the alarm that sugar – and not fat – was the greatest danger to our health. But his findings were ridiculed and his reputation ruined. How did the world’s top nutrition scientists get it so wrong for so long?

For probably 25 years after my 1989 heart attack, I followed a low fat diet. If you go low fat, the only think g left to eat is carbs. When I heard of a friend’s surgeon wife following an Atkins diet, I told him all I knew about low fat diets and essentially called his wife crazy. A year or so ago, I finally decided to heed my doctor’s complaint that my blood sugar was too high, nearing a worrisome level. I stumbled on a book that talked about lowering your blood sugar level. To my surprise, the book was about minimizing your carbs. I gave those ideas a try. The next time I had occasion to have my blood sugar measured, it was so low that I was told I could afford to eat more carbs. In the meantime, I had lost an additional 15 pounds beyond where my low-fat diet had gotten me. (It may not have been the low-fat diet that had helped me gain and then lose 40 pounds. That loss may have come from contracting noro-virus on a cruise. The thought of eating at the company cafeteria after returning from the cruise, turned me into bringing my own food to work.)
