Washington | Early one Saturday, I headed to a "sugar detox" seminar at my gym. I didn't expect it to be a hot ticket, but when I opened the classroom door every seat was taken.

One was filled by "Grandma Teresa", as she introduced herself, who had brought along her two granddaughters, ages 11 and 13, because "sugar is really bad and I want them to learn as much as they can when they are still young". The other participants, all women from their 30s to 70s, said they wanted to curb their sugar intake for a variety of reasons - to ease a health struggle; to lose weight; or to reduce their risk of diabetes, heart disease, cancer and dementia.
