janeainsworth fructose being converted into fat and stored in the liver? Not glycogen?.... goes off to read wiki.... Not a chemist but squinting at the wiki entry seems to indicate that the primary metabolite is glycogen and after this is replenished in the liver the excess will form fatty compounds. So I guess it depends how much you consume, and when. I'm sure we agree its bad for your teeth!!! 
bags the natural sugars in dried fruit are a much higher proportion if you calculate by weight or volume because so much of weight and volume in fresh fruit consist of water. A handful of sultanas = a small bunch of grapes.
If you make wholemeal bread with flour, water and yeast the only added sugar is that needed to activated the yeast. And this is then broken down chemically by yeasts.
It would be a start, wouldn't it, if we talked about added sugar. It is clear that most people in this country consume more than 6 teaspoonfuls a day. The kind that is included in cake, biscuits, soft drinks, many processed food. On the ingredients section of the labelling it will be listed as sucrose, lactose, fructose, corn syrup etc.
Me? Probably about 6 teaspoonfuls added sugar a week.
