Do you enjoy an occasional cocktail? You have probably heard the phrase “everything in moderation.” This may not apply to alcohol. Associations between heavy alcohol consumption and cancer risk have been observed consistently, irrespective of the type of alcoholic beverage. However, research has now found associations between light alcohol consumption and cancer risk, specifically cancer of the mouth, esophagus, larynx, breast, liver, and colon. New research has found the specific culprit too.
The culprit is a chemical compound called acetaldehyde. It is a natural byproduct of the alcohol manufacturing process. Acetaldehyde has been found to damage the DNA of stem cells. Bits of DNA may be deleted broken. Even parts of chromosomes can be moved about and rearranged in the presence of acetaldehyde. Why is this significant? Our body makes its own stem cells. These cells are designed to replace our aging cells with ones that are younger, stronger, and healthier. But when stem cells suffer DNA damage, they spread their genetic damage throughout the body.
The body does have a defense against acetaldehyde. It is a group of enzymes called acetaldehyde dehydrogenases. When these enzymes are working properly, they help convert acetaldehyde into acetate, which the body can use as an energy source. However, it has been found that alcohol clearance and DNA repair systems in our body are not perfect and alcohol can still increase the risk of cancer.
Comments from Dr. Thomas: I recommend avoiding alcoholic beverages of any kind. As an alternative, have a “virgin” (non-alcoholic) drink instead. If you are a fan of red wine, as an alternative, I recommend organic unsweetened dark cherry juice, pomegranate juice, or grape juice. The flavor and bouquet of these juices are heavenly, and they are rich in life-extending polyphenols such as resveratrol. Drink up!
