In this study, lab mice were made to compete for territory and reproductive partners as they would in real world situations. One group of mice was fed 25% of their daily Calorie allotment in refined white sugars – equivalent to the amount of about three cans of soda per day – and the other group received normal food.
Even though the refined white sugar group in this study did not exhibit noticeable signs of diabetes or obesity, they reproduced less frequently and died more frequently. The study also indicated that the toxic effects from the refined white sugars was very similar to the effects of inbreeding on mice. It was as if the mice’s parents were cousins, leading to genetic abnormalities.
