MILAN - Is there some negative nutritional aspect linked to drinking carbonated water? It 'a question which is often asked and which often does not receive a sufficiently correct answer. Experts at the Mayo Clinic have tried to shed light on this question, starting from the separation of drinks: on one hand, sparkling mineral water, and on the other, carbonated drinks.

Confusion

Experts explained that the original belief that carbonated water is harmful stems from the belief that the latter prevents calcium absorption and, consequently, increases the risk of osteoporosis. In actuality there is no evidence of this and, at most, the confusion is dictated by old research that found a link between so-called “carbonated cola drinks” and low bone mineral density. This association was not found for carbonated mineral water and this removes any impediment to sipping a glass of bubbling water.

Bubbles

Sparkling water is a mineral water that is particularly rich in carbon dioxide. Sometimes its famous bubbles are a characteristic of natural origin (as is the case of sparkling water that flows from some springs), but it can also be specifically treated by adding carbon dioxide (Also called CO2, carbon dioxide or E290). Like natural mineral water, carbonated water is also calorie-free.

Benefits of carbonated water

Beyond its organoleptic characteristics, which may be more or less pleasing, the bubbles stimulate taste receptors until resulting in an anesthesising effect, and a greater sense of freshness on the palate. This is why so many people believe it is more refreshing than common water, although in reality this effect is only temporary. When sipped before meals, carbonated water helps to dilate gastric walls and reduce appetite. If sipped during meals, on the other hand, the dilation of the walls of the stomach instead stimulates secretion of gastric juices.
