Moderate levels of added sugar reduce survival and compromises fitness and reproduction, in a lab animal model.
Previously, a number of studies have suggested that the consumption of added sugar may correlate with a number of diseases. Wayne Potts, from the University of Utah (Utah, USA), and colleagues administered a diet containing 25% added sugar to laboratory mice, observing that the female animals died at twice the rate of animals fed a standard diet; and males were 25% less likely to maintain territory and reproduce. Noting that this added 25% corresponded to an equivalent of humans consuming three cans of soda, the study authors submit that: “These findings represent the lowest level of sugar consumption shown to adversely affect mammalian health.”
