Is sugar an invisible killer?

Even 'safe' levels of sugar could be having invisible adverse effects on our health, say American researchers. 
Researchers gave mice the equivalent of a healthy human diet plus three cans of fizzy drink a day and found the female animals died twice as fast as those whose food was not largely composed of sugar. Male mice consuming the sugary diet were less able to hold territory and reproduce, leading scientists to speculate that sugar has a damaging effect on the health of mammals, including humans.
Scientists from the University of Utah said the mice showed no sign of suffering serious physical changes in their bodies. Writing in the online edition of the journal Nature Communications, the researchers said: 'Our results provide evidence that added sugar consumed at concentrations currently considered safe exerts dramatic adverse impacts on mammalian health.'
Mice on the experimental diet received 25 percent of their energy intake in the form of added sugar, no matter how many calories they ate. In human terms this was equivalent to a person eating a normal healthy diet plus three cans of sugar-sweetened fizzy drinks a day. After 32 weeks, more than a third of the female mice fed extra sugar died - twice the number fed a non-sugary diet. 
The death rate of males was not affected, but their survival behaviour was.  Males on the sugary diet acquired and held on to 26 percent fewer territories than their normal diet nest-mates and produced 25 percent fewer offspring.
