The effect of Chlorella on the alcohol metabolism of healthy volunteers
Presented at the Annual Meeting of the Japan Society for Bioscience, Biotechnology, and Agrochemistry 2011
- Study Objectives
- Alcohol consumed as alcoholic beverages is absorbed from the stomach and duodenum, and
is decomposed in the liver into water and carbon dioxide as final products to be excreted out
of the body. During the course of decomposition, acetaldehyde is formed, and this substance
is responsible for the nauseous feeling experienced after drinking. In approximately half of
the Japanese population, the ability to break down acetaldehyde is reduced, and thus
alcohol-related symptoms, such as a red face, appear. Assuming that a faster metabolism of
alcohol would make these peoples' life with alcohol more comfortable, we investigated the
potential effects of chlorella on human alcohol metabolism and physical discomfort.
- Experimental procedures
- This study was conducted on a total of six healthy males who were informed as to the purpose
of the study. Subjects were divided into two groups: the control group and the chlorella group.
Subjects in the control group were orally given only water, whereas subjects in the chlorella
group were orally given water and 40 tablets of chlorella. All subjects ate an identical meal
and then ingested either only water or water plus chlorella tablets, and 30 minutes later
consumed alcohol at 0.5 mg/kg body weight (which is equivalent to 750 mL of beer
containing 4% of alcohol for a person weighing 60 kg). Subsequently, blood and expired air
samples were collected over time and changes in alcohol concentrations were examined. In
addition, subjective feelings of physical discomfort, such as sleepiness, rapid heartbeat, and
glow, were measured using visual analog scale (VAS) testing.
- Results
- Chlorella ingestion before consuming alcohol led to significantly decreased ethanol
concentrations in the blood, and a tendency of decreasing acetaldehyde concentrations in the
blood and ethanol concentrations in expired air (Fig. 1). In addition, sleepiness, rapid
heartbeat, and glow were significantly reduced by chlorella ingestion compared with chlorella
group (Fig. 2). These findings suggest that chlorella ingestion can promote alcohol
metabolism in humans.
