Acetaldehyde associated with alcoholic beverages was recently classified as carcinogenic (Group 1) to humans based on uniform epidemiological and biochemical evidence. ALDH2 (aldehyde dehydrogenase 2) deficient alcohol consumers are exposed to high c

The aim of this study was to explore oral exposure to carcinogenic (group 1) acetaldehyde after single sips of strong alcoholic beverages containing no or high concentrations of acetaldehyde. Eight volunteers tasted 5 ml of ethanol diluted to 40 vol.

Background: Acetaldehyde, associated with alcohol consumption, has recently been classified as a group 1 carcinogen in humans. Achlorhydric atrophic gastritis is a well-known risk factor for gastric cancer. Achlorhydria leads to microbial colonizatio

Background: Normal colonic bacteria possessing alcohol dehydrogenase activity can oxidize ethanol to acetaldehyde. Acetaldehyde recently has been shown to be a local carcinogen in humans. The aim of the study was to examine the effect of lactulose fe

Acetaldehyde is a local carcinogen in the digestive tract in humans. Atrophic gastritis leads to microbial colonization of the stomach, which could enhance microbial production of acetaldehyde from ethanol. The aim of the study was to study microbial

Background: Carcinogenic acetaldehyde is produced from ethanol locally in the upper digestive tract via alcohol dehydrogenases (ADHs) of oral microbes, mucosal cells, and salivary glands. Acetaldehyde is further oxidized into less harmful acetate mai

Background: Acetaldehyde is a known local carcinogen in the digestive tract in humans. Bacterial overgrowth in the hypochlorhydric stomach enhances production of acetaldehyde from ethanol in vivo after alcohol ingestion. Therefore, microbially produc

Background: Acetaldehyde, produced locally in the digestive tract, has recently been shown to be carcinogenic in humans. Aim: To examine the effect of iatrogenic hypochlorhydria on intragastric acetaldehyde production from ethanol after a moderate do

Background: Metronidazole leads to the overgrowth of aerobic flora in the large intestine by reducing the number of anaerobes. According to our previous studies, this shift may increase intracolonic bacterial acetaldehyde formation if ethanol is pres

Many colonic aerobic bacteria possess alcohol dehydrogenase (ADH) activity and are capable of oxidizing ethanol to acetaldehyde. Accordingly, some ingested ethanol can be metabolized in the colon in vivo via the bacteriocolonic pathway for ethanol ox
