Fructose fever
I was fascinated by the article “Sweet confusion” (SN: 6/1/13, p. 22) about the ambiguous health effects of high fructose corn syrup. I was surprised, however, to find little mention of taste, flavor and satiety. I can clearly recall from my childhood the satisfaction from a bottle of Coca-Cola. The transition in America in the 1970s from sucrose to corn syrup as a sweetener in soft drinks was brought home to me in my travels to Central America in the ’80s and ’90s, where cane sugar was still used as a sweetener. Drink a soft drink with cane sugar and you are satisfied. Satiety is the key to the obesity epidemic.
