Sugar in soda is a known culprit in promoting diabetes and obesity. But a new study takes a look at another potential player in the soda-obesity equation: carbonation.
New research published in the journal Gastroenterology suggests that carbonation in sugary drinks can affect the brain's perception of sugar, making it think sugar consumption is less than it actually is.
The Italian researchers also found that a certain amount of carbonation seems to keep the brain from being able to tell the difference between sweet from sugar and sweet from artificial sweeteners.
