Of the option between drinking water or soda, there appears to be evidence to support the assertion that water is the healthier choice, yet misconceptions remain. Part of the water or soda confusion centers around the effects of diet versus regular soda, specifically pertaining to weight gain, but the amount of daily water or soda fluid intake has also come under debate.
Should we really drink eight glasses of water, anyway?
Asked the question, “How much water should I be drinking?“, pinning down the scientific evidence for the “drink eight glasses of water a day” advice is difficult. Where did this suggestion originate? “I can’t even tell you that,” says Barbara Rolls, a Pennsylvania State University nutritionist, “and I’ve written a book on water.” Jurgen Schnermann, a National Institute of Health kidney specialist, maintains that much, if not all, of the body’s daily fluid loss is made up in food intake.
Can drinking soda cause weight gain?
If additional water intake is not vital to daily hydration, is drinking soda harmful? A study at the University of Texas Health Science Center showed that people who drank at least three servings of diet soda per day doubled their risk of becoming overweight over eight years. “Even if diet drinks prove to aid long-term weight loss when used to replace sugary beverages, they may promote weight gain when consumed instead of unsweetened beverages,” stated Dr. David Ludwig, writing for the Journal of the American Medical Association.
Is drinking soda harmful?
Even for those not watching their weight, water or soda choices may have health consequences. A 2006 study from Tufts University in Boston suggest that drinking cola soft drinks can result in bone loss. Lead author of the study, Katherine Tucker, Ph.D., sites phosphoric acid, which is unique to cola drinks, as the culprit. Breaking down this compound increases acidity in the blood. To neutralize acidity, hydrogen ions bind with minerals, including calcium. If enough calcium is not present in the blood to neutralize the acidity, “the body draws calcium from the bones,” says Tucker.
Phosphoric acid
Defenders of sodas in the water or soda controversy maintain that phosphoric acid, which in its pure form can eat through metals, should not be compared to edible acids. Dr. Marc Hellerstein, an Associate Professor of Nutritional Sciences at the University of California in Berkeley states, “Sweeteners are generally safe – it takes very high doses to show problems in animals, and I know of no problems proven in humans.” However, Dr. Hellerstein also states that drinking regular soda instead of water leads to a host of problems, including weight gain, triglycerides in the blood, and tooth decay. Plus, a person is simply not getting the health benefits of water, or gaining the help of water to prevent disease.
Whether to choose water or soda may depends upon personal goals. Dieters and those scrupulous about their health will probably choose water. However, no hard evidence exists to prove that indulging in an occasional soda drink is harmful.
