As if sugar doesn’t have enough PR problems, a new study  published in January suggests it encourages the growth and spread of breast cancer tumors in rats. Common sugar is half fructose and half glucose, and the researchers showed that the fructose half shows particularly carcinogenic activity. This is similar to recent evidence that pancreatic cancer cells can distinguish between fructose and glucose — and perform better  when fed the former.
