The Week -- A leading scientist believes sugar does more than expand our waistlines — it’s a “toxic substance” that causes heart disease and cancer. Just about everyone admits that eating too much sugar can rot your teeth and expand your waistline. But Dr. Robert Lustig, an expert in childhood obesity at the University of California, San Francisco, believes sugar can be lethal. Lustig says sugar causes heart disease, diabetes, hypertension, and many forms of cancer. “It has nothing to do with the calories. It’s a poison by itself,” he says.
