Step Away From the Soda!
A new study underscores an important health message I’ve been preaching for years: Sugar is toxic! In my book, True Nutrition-European Secrets for American Women, I talk extensively about research by experts such as Robert Lustig, M.D., who has been proclaiming for years that sugar is toxic and we’re slowing killing ourselves with the stuff. Evidence that he’s right continues to mount.
In the present study, researchers at the University of Utah raised mice on two different diets. One was ordinary chow, while the other featured 25% added sugar—the equivalent of a human drinking just three soft drinks a day. Female mice died at twice the normal rate, while males were less successful at reproducing, or holding territory. “Our results provide evidence that added sugar consumed at concentrations currently considered safe exerts dramatic adverse impacts on mammalian health,” wrote researchers.
Previous studies on the effects of added dietary sugar involved even larger amounts of sugar. The present study relied on smaller amounts that are currently considered “safe”. The 25% added sugar amount is in keeping with the amounts of added sugar many people consume every day. Although the mice didn’t show outward signs of distress, such as obesity or other metabolic symptoms, their health clearly suffered. The health deficits were similar to those seen among mice that have been inbred.
What’s most alarming is the fact that the relatively modest amount of added sugar was similar to the diet of one-quarter of Americans. Sugar consumption by Americans has increased 50 percent since the 1970s, noted one researcher, accompanied by a dramatic increase in metabolic diseases such as diabetes, obesity, fatty liver and cardiovascular disease.
