Mice give us reasons to avoid added sugar

iStock_000014015871XSmallResearchers at the University of Utah found that when mice were fed a diet where 25% of the calories came from added sugar, the mortality rate of female mice doubled.

Let’s consider the equivalent amount of added sugar in our own diets. “Added sugar” means sugar that comes from processed foods, not sugar that is naturally in non-processed foods like fruit. Surprisingly, it doesn’t take much to add those calories- for a person who normally eats a healthy diet, it is the equivalent of adding three cans of sweetened soda a day. Approximately 13-25% of Americans currently consume a diet with at least 25% added sugar.

The mouse experiments lasted for about 8 months, and 35% of the female mice on sugar-added diets died during that time, in comparison to 17% of the female control mice. (The average mouse lifespan is about two years.) While males on sugar-added diets did not show an increase in mortality rates, they were less dominant and produced 25% fewer offspring than males on the control diet.

As more tests are developed to understand the impact of potential toxins in our food and environment, it wouldn’t be surprising if many of the chemicals and additives we encounter every day are scrutinized further. In the meanwhile, limiting extra sugar might not be a bad idea… just saying.
