Cake makes us feel full so we reduce the amount we subsequently eat. Digestion takes hours, allowing our bodies time to deal with the sugar load. This doesnt happen when we drink a soda. For millennia, humans quenched their thirst with water. Unlike solid foods, liquid calories dont trigger our sense of feeling full. We take in excess liquid calories without being aware of it. When we drink soda, two sugars (glucose and fructose) are immediately absorbed. The glucose enters the bloodstream, signaling the pancreas to churn out insulin. The fructose -- the sweet part -- goes to the liver, where much of it gets converted into fat. The overworked pancreas eventually poops out from exhaustion. Diabetes is the result, with its risks of amputations, blindness, kidney dialysis, heart attacks and strokes. Meanwhile, the fructose is converted into fats that infiltrate our organs and clog the hearts arteries, causing heart attacks early in life. The liver itself gets packed with fat. Before reaching the breakdown point, the liver goes deaf to the insulin signal, in medicine known as insulin resistance. The pancreas has no choice but to shout, ie, make more insulin, thus hastening the pancreatic exhaustion and the onset of diabetes. Dr Jeff Ritterman, Cardiologist, Editorial, San Francisco Chronicle
