Shiitake mushroom extract, particularly with lentinic acid, can reduce blood alcohol levels by speeding up alcohol breakdown and slowing absorption. This suggests shiitake may help mitigate alcohol
Area of Science:
- Biochemistry
- Pharmacology
- Gastroenterology
Background:
- Chronic alcohol consumption is a primary cause of alcoholic liver diseases.
- Ethanol metabolism and absorption significantly influence blood alcohol concentrations.
Purpose of the Study:
- To investigate the effects of shiitake mushroom extracts (high and low lentinic acid content) on ethanol metabolism and absorption.
- To determine the role of lentinic acid in shiitake's potential hepatoprotective effects against alcohol.
Main Methods:
- Administration of shiitake extracts (Shiitake-H and Shiitake-N) to assess impact on plasma ethanol and acetaldehyde levels.
- Measurement of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) activities in the liver and stomach.
- In vivo assessment of ethanol absorption from ligated stomach and jejunal loops with shiitake extracts.
Main Results:
- Both shiitake extracts reduced plasma ethanol and acetaldehyde levels and increased ADH/ALDH activity.
- Shiitake-H demonstrated more potent effects than Shiitake-N, indicating lentinic acid's importance.
- Shiitake-H significantly inhibited ethanol absorption from both the stomach and jejunum.
Conclusions:
- Shiitake mushroom extract, especially Shiitake-H containing lentinic acid, accelerates ethanol metabolism in the stomach and liver.
- Shiitake-H effectively inhibits ethanol absorption in the gastrointestinal tract.
- Lentinic acid is identified as a key functional component in shiitake for managing alcohol's physiological effects.
