In reply to Antigua:
Things like high fructose corn syrup are 100% sugar. A big problem is that there is just so much sugar of all kinds added to loads of foods so many people eat huge amounts without realising it. There are loads of names for simple sugars, all of these things on product labels are sugar:
Sugars ending in -ose include: Sucrose, Maltose, Dextrose, Fructose, Glucose, Galactose, Lactose, High fructose corn syrup, Glucose solids
Just because it doesn't end in -ose, however, doesn't mean it isn't sugar. There are plenty of other names as well that may or may not sound like sugar.
Regardless of how they sound, the following are all sugar:
Cane juice, Dehydrated cane juice, Cane juice solids, Cane juice crystals, Dextrin, Maltodextrin, Dextran, Barley malt, Beet sugar, Corn syrup, Corn syrup solids, Caramel, Buttered syrup, Carob syrup, Brown sugar, Date sugar, Malt syrup, Diatase, Diatastic malt, Fruit juice, Fruit juice concentrate, Dehydrated fruit juice, Fruit juice crystals, Golden syrup, Turbinado, Sorghum syrup, Refiner's syrup, Ethyl maltol, Maple syrup, Yellow sugar
So you see how much can be in food without us realising it. A lot of low fat foods have extra sugar added to make it taste better.
Does that help?
