Sugar. When I was young, I was a strange kid who often didn' t even want ice cream or other desserts. I took after my father who wasn' t a sweet eater. Neither of us wanted sugary foods. Unfortunately, advancing years brought out my inner child. I' m now a hardcore sweet eater, at least some of the time. I cycle with it. We know sugar isn' t good for our teeth. We know it puts on unhealthy weight. But breast milk is sweet for a reason. The human infant is drawn to sweets, and we don' t seem to outgrow that attraction.
