New Beneficial Property Found in Carbonated Water

BMJ: Carbonated water helps cells absorb sugar more efficiently
Carbonated water can influence metabolism by accelerating sugar absorption by cells. This was reported by scientists from Kyushu University (Japan). Their study results were published in the journal BMJ Nutrition, Prevention & Health.

According to the study, carbon dioxide from carbonated water is partially absorbed into the bloodstream after ingestion. There, it converts into a substance called bicarbonate, which affects the chemical composition of the blood — specifically, it slightly increases the acidity level (pH) inside red blood cells (erythrocytes). This change triggers the glycolysis process — a mechanism by which cells start to process sugar (glucose) more actively and use it to generate energy.

Scientists compared this effect to what happens during hemodialysis — a blood-cleaning procedure used in people with kidney failure. Carbon dioxide is also used there and similarly stimulates metabolism in cells.

Although the reduction in blood sugar levels among participants was small, researchers believe this mechanism may play a role in regulating energy metabolism. They say carbonated water does not aid in weight loss but can cause a slight feeling of fullness and temporarily lower glucose levels. According to the authors, these observations require further research, especially regarding the prevention of metabolic disorders.
