Many people drink diet soda instead of regular soda because they are trying to reduce the intake of calories. Since diet soda usually has no calories, it is widely believed to be a good way to maintain or lose weight.
But a study recently presented at the annual meeting of the American Society of Nephrology may make you think twice about drinking diet soda. In this study, the researchers looked at the participants of the national Nurses' Health Study and selected more than 3,000 women who had perfectly normal kidney function. These women were asked about their eating habits, including how much soda they drank, both regular (sugar-sweetened) and diet (artificially-sweetened).
Women who had two or more servings of diet soda a day had double the risk of faster kidney function deterioration. Women who drank regular soda did not have kidney function decline.
Look at the ingredients of a very popular diet soda: Carbonated Water, High Fructose Corn Syrup, Caramel Color, Phosphoric Acid, Natural Flavors, Caffeine, Aspartame (NutraSweet), Potassium Benzoate, Citric acid.
There is nothing healthy about this drink. Your body does not need any of these ingredients, except water. They are all potentially harmful and should be avoided.
Dark sodas have phosphoric acid, which stimulates the removal of calcium from the bones, making them weaker.
And by the way, just because regular soda did not cause kidney problems in this study, it is very far from being a healthy beverage. Most of the ingredients are the same, except that the artificial sweetener is replaced by either sugar or high fructose corn syrup. Both of these have been linked to higher risk of diabetes, hardening of the arteries, heart disease, and stroke.
All man-made "foods," including sodas, should be avoided, but especially diet sodas because of their negative effect on the kidneys.
