ABSTRACT
Wine but not alcohol increases gastric acid secretion. Our aim was to clarify the influence of a moderate dose of wine, of its minor constituents, and of alcohol, on gastric emptying; and postprandial serum levels of glucose, insulin, triglycerides, NEFA, and acetate. Materials and Methods: 12 healthy subjects were studied on four different days after ingestion, with the test meal, of 183 ml water; alcohol, 11.9% v/v; dealcoholated red wine; or red wine, alcoholic concentration 11.9% v/v. Gastric emptying of an 800 Cal solid meal was studied by a previously validated ultrasonographic method; serum parameters were studied at 30' intervals for 240 min, calculating the area under the curve. The ANOVA for repeated measurements and, if positive, the student's t test for paired data were used for statistical analysis, considering 0.05 as the limit for significance. Mean ± 1SEM are shown. Results: gastric emptying was significantly influenced by the beverages (p < 0.05, ANOVA). It was significantly delayed after wine (259 ± 13.1 min) compared with water (199.1 ± 12.1, p < 0.05). Alcohol (221 ± 13.5, p < 0.05) and dealcoholated wine (226.8 ± 13.3, p = 0.055) produced an intermediate delay. The postprandial increase of glucose was significantly higher after ingestion of water than after the other beverages (p < 0.01), independently from the insulin response, not significantly different during the four tests. Triglycerides were slightly higher after ingestion of the alcoholic beverages than after water, but were markedly reduced after dealcolated wine compared with the other beverages (p < 0.05 For all contrasts). Both alcohol containing beverages produced a highly significant postprandial increase of serum acetate. Conclusions: Red wine produces a marked delay in gastric emptying, only partially explained by its alcoholic content. Moreover, red wine, alcohol, and minor wine constituents reduce the postprandial increase of serum glucose...
