Acetaldehyde is a naturally occurring chemical that is present in some amount in all beer. Unfortunately for us beer drinkers acetaldehyde is toxic for the body. Ideally, the acetaldehyde beer is to be as low as possible. It will affect the beer in an undesirable way with a green apple odor and sense of taste.
Recall we said acetaldehyde was toxic to your body. While it naturally occurs acetaldehyde beer you buy. Acetaldehyde is also formed in the body when your body breaks down alcohol. An enzyme called alcohol dehydrogenase breaks down alcohol into acetaldehyde. Why do we care? Acetaldehyde is 30 times more toxic than alcohol.
So your body again tries to break it down with another enzyme and glutathione, a powerful antioxidant that is crucial for liver detoxification. Cysteine helps the body with this process. Eggs contains Cysteine. Also B1 (thiamin) & C Vitamins (fruits & vegetables) help your body process toxic acetaldehyde.
