pass on carbonated cocktails.

> The air bubbles in champagne and carbonated

mixers such as tonic water cause the liquid to remain in your stomach

longer, increasing alcohol absorption. If you want to keep a clear head,

limit yourself to a drink or two and choose a non-carbonated drink such as

white table wine.

Gastric gas and fluid emptying assessed by magnetic resonance imaging.

Magnetic resonance imaging (MRI) was used to characterize the volumes and

rates of gastric emptying of both liquid and gas following the ingestion of

beverages of varying carbonation and carbohydrate levels. Eight subjects

drank 800 ml each of four test beverages in a counterbalanced order: water,

a non-carbonated carbohydrate-electrolyte solution (NC), a lightly

carbonated carbohydrate-electrolyte solution (PC), and a carbonated cola

(CC). T2-weighted, echoplanar images (25-30 contiguous slices, 1 cm thick,

256 x 128 matrix, TE = 80, 40 cm FOV) of the abdomen were collected at

minutes 3,110, 20, 30, 45, and 60 following beverage ingestion. Images were

analyzed for gas and liquid volumes. Water and NC emptied the most rapidly,

with half times of 21(3) and 31(3) min, respectively [mean (SE)]. PC emptied

significantly slower [47 (6) min] and CC slower yet [107 (8) min]. The

carbonation content of the beverage accounted for 84% of the variation in

emptying time, whereas carbohydrate content did not account for any

significant variation. The gastric gas volume of the CC was higher at 2 min

post-ingestion compared with all other drinks; however, the rate of emptying

of the gas was the same among all beverages. Significantly greater total

gastric volumes (gas+ liquid) were associated with the ingestion of CC, and

accordingly produced a greater severity of gastric distress, as evaluated

with a gastric distress inventory. The high gastric gas volumes

(approximately 600 ml) after ingestion of CC suggested a potential source of

error in body composition using standard hydrostatic weighing methods. This

prediction was tested in nine additional subjects. Ingestion of 800 ml of CC

prior to hydrostatic weighing resulted in a 0.7% underestimate of body

density and thus an 11% overestimate of percentage body fat compared to

measurements made before beverage consumption.
