Beer and wine but not whisky and pure ethanol do stimulate release of gastrin in humans.
In humans, the action of ethanol on gastrin release is still unclear and that of alcoholic beverages greatly unknown. We studied the effect of a drink of various concentrations of pure ethanol and several commonly ingested alcoholic beverages on plasma levels of immunoreactive gastrin in 6 healthy human volunteers and compared the results to a protein-rich meal. A drink of distilled water (250 ml) and of pure ethanol (250 ml or 125 ml in the case of 40% v/v ethanol) in concentrations (4, 10, 20 and 40% v/v) normally present in beer, wine, liquor and whisky did not stimulate plasma gastrin levels above basal. Of the alcoholic beverages given only whisky (125 ml) did not stimulate gastrin release. Beer, red and white wine (250 ml each) caused a rapid increase in plasma gastrin concentrations with a peak at 15-20 min, basal levels being reached 60 min after starting the drink. The 60-min integrated plasma gastrin response to beer, red and white wine was about 50% of the gastrin response to the protein-rich (steak) meal (883 +/- 297 pmol X min X 1(-1); mean +/- SE). A drink of 250 ml of white wine together with the meal did not cause a significantly higher integrated gastrin response than the protein meal with 250 ml of distilled water. We conclude that commonly ingested alcoholic beverages such as beer, red and white wine, but not whisky, are potent stimulants of gastrin release in humans. The ethanol content of these beverages cannot be responsible for the increase in plasma gastrin levels, since oral ingestion of pure ethanol in equivalent concentrations and amounts did not elicit a rise in plasma gastrin levels. Some unknown ingredients present in beer and wine are most likely responsible for the gastrin release by both alcoholic beverages.
