While it’s common knowledge that drinking any form of soda raises health risks like diabetes, the surprising news from this study was that they found drinking “diet” soda actually increased the Type 2 diabetes risk more than drinking regular soda. Don’t be fooled by the “sugar free” label into thinking that the sugar substitutes like aspartame aren’t just as harmful. In fact, new research is proving they are even worse for your health.
The study was conducted by France’s National Institute of Health and Medical Research and covered 66,118 middle-aged women whose dietary habits and health were tracked from 1993 to 2007.
The results were unexpected. Though it’s well-known that people who consume a lot of sugar are more likely to develop diabetes, the researchers found that participants who drank “light” or “diet” soft drinks had a higher risk of developing Type 2 diabetes than those who drank regular, sugar-filled sodas. Those who drank 100 percent natural squeezed fruit juices instead had no additional risk.
Women who choose artificially flavored soft drinks usually drink twice as many of them as women who choose regular soda or juice—2.8 glasses per week compared to 1.6 glasses. “Yet when an equal quantity is consumed, the risk of contracting diabetes is higher for ‘light’ or ‘diet’ drinks than for ‘non-light’ or ‘non-diet’ drinks,” the researchers, epidemiologists Francoise Clavel-Chapelon and Guy Fagherazzi, said in a statement. Women who drank up to 12 ounces of artificially sweetened beverages per week were 33 percent more likely to develop the disease, and women who drank about 20 ounces) per week had a 66 percent increase in risk.
Drinking sweetened beverages increases the risk of becoming overweight, which is itself a risk factor in developing diabetes. But the study didn’t find that the results were the same even among overweight women. So how can artificially sweetened drinks be making the problem worse if they’re fat- and calorie-free?
How Can These Results Be Explained?
“With respect, in particular, to ‘light’ or ‘diet’ drinks, the relationship with diabetes can be explained partially by a greater craving for sugar in general by female consumers of this type of soft drink,” the researchers explained. “Furthermore, aspartame, one of the main artificial sweeteners used today, causes an increase in glycaemia and consequently a rise in the insulin level in comparison to that produced by sucrose (normal table sugar).”
According to the American Diabetes Association, about 25.8 million children and adults in the United States have diabetes—about 8.3 percent of the population. The disease is the leading cause of new cases of blindness in people age 20 and older, and can also cause heart disease, stroke, high blood pressure, kidney disease, and damage to the nervous system. Type 2 diabetes—which can be controlled by diet and exercise rather than a daily insulin injection—is the most common form of diabetes in the United States.
