The Negative Aspects of Alcohol - Alcohol Is a Toxin That Your Body Must Metabolize and Excrete
Our ability to break alcohol down into less toxic metabolites didn’t arise because of our tendency to seek out fermented fruits. Over the course of an average day, the average human digestive system produces about three grams of ethanol just from the gut flora fermenting the gut’s contents. If we didn’t have the ability to metabolize and detoxify ethanol, those three grams would add up real quick and represent a huge toxin load on our bodies.
After alcohol is consumed, a number of enzymatic reactions ensue. In the liver, an enzyme called alcohol dehydrogenase converts the ethanol to acetaldehyde, an incredibly toxic compound that’s been implicated in causing many hangover symptoms. An enzyme called acetaldehyde dehydrogenase converts the acetaldehyde into acetic acid, or vinegar, which is harmless unless you’re a cucumber. From there, you’re good to go. Sounds simple enough, right? Just let the enzymes do their thing. As long as you make those enzymes, the alcohol will be safely and effectively metabolized into table vinegar which can then be extracted to form a delicious salad dressing (that last part isn’t true).
Unfortunately, not everyone produces the same amount and quality of detoxifying enzymes. Many people of East Asian descent possess a dominant mutation in the gene that codes for aldehyde dehydrogenase, making it less effective. While they’re less likely to be alcoholics, folks with the mutation (characterized by a “flushing” upon ingestion) are at an elevated risk of liver damage and esophageal cancer.
