Apparently, if you were stranded on a desert island (assuming that there was a fresh water supply) and the only food you had to eat was refined sugar; if you ate NOTHING ie. starved yourself; you would live LONGER than if you ate sugar!
It is the only substance we consume with zero nutritional value. No fat, no protein, no water! Just pure empty calories of carbohydrate.
I find it completely frustrating that food manufacturers feel the need to put in practically all of their products. Try getting ham from a supermarket with no sugar in it - It is almost impossible. Even ham from the deli counter can have sugar in it. (They often call it dextrose - Pretty much anything ending in -ose is a sugar)
