I'm not buying it without a comparison of water to carbonated water.
Its long been understood that soda w/o carbonation isn't palatable because its too sweet and animals stop consuming it. However, when carbonation is present it masks the sweetness which result in increased consumption.
So I think they're probably measuring a secondary effect here.
- Etheryte 9y agoThe paper includes carbonated water, see https://news.ycombinator.com/item?id=14352563 https://news.ycombinator.com/item?id=14352563
- theptip 9y agoOne of the experiments measures serum ghrelin levels in humans after consuming a fixed volume of liquid; you can directly compare degassed carbonated beverage (DCB) and regular carbonated beverages (RCB) in their tables. This controls for the concern you raise above regarding palatability of the beverage, so I don't think that can be a factor there. Critically, there's a statistically significant difference between water and RCB, but not between water and DCB (though the ghrelin level was higher in DCB than water). From my reading of the paper your concern could certainly be relevant in the rat experiment; I couldn't see any attempt to control for or measure the amount of liquid that the rats consumed, so they could have been drinking less decarbonated beverage.
- dahauns 9y agosoda w/o carbonation Soda without soda? :) As a non-native speaker, this continually fascinates me...
- overcast 9y agoSoda, is just short for soda pop, which is the sweetened, carbonated water beverage. So soda without the carbonation is just sweetened water. Flat soda is a fairly common term to describe soda that has lots its carbonation.
- dahauns 9y agoYeah, I know. But everywhere else in the world, "Soda" is just the name for (Natrium-)carbonate...
