I have spent the last three to four weeks reading about and viewing videos about what scientists, doctors, neurologists, physicians, cardiologists and just 'people' have and are finding out about what sugar and carbohydrates are doing to us humans. It is daunting and does not make happy reading especially of you have been on Dr Ornish's recommended diet for the last year as my husband and I have. We have done a direct about turn! Search and find the following, not all by a long chalk but enough to convince me: On You Tube: The Bitter Truth, by Dr Robert Lustig. A long video but worth sticking with. A lot and a website by Dr Joseph Mercola, Dr Robert Johnson: see Cereal Killers, The Movie. Dr David Perlmutter, who is a neurologist and nutritionist: get his book: Grain Brain, join his website and change your diet.
