White sugar is an almost chemically pure substance that is rapidly absorbed and has a powerful effect on body chemistry. It contributes only calories and no nutrients. With no lasting satiety value it is conducive to consuming far more calories than desirable. (Dychtwald, Ken, PhD., ed. Wellness and Health Promotion for the Elderly. p 182. MD:Aspen Publication, 1986.)
