Ever drank a home brewed beer and it had a green apple taste and smell. Almost tasted and smell artificial like a solvent? Acetaldehyde beer often happens. The smell is often from acetaldehyde, it is a byproduct of ethanol.
Acetaldehyde is in all beers at some levels. Some American beers have it in their flavor profile. One example is Budweiser. Unfortunately, it can be found at an extremely high level in some homebrew cases. This makes the flavor of the beer bad and sometimes undrinkable.
When you drink your body turns ethanol into acetaldehyde. Unfortunately, this is an alcohol-related toxin, that is often linked to hangover symptoms. The liver’s stores of glutathione quickly run dry when large quantities of alcohol enter the system. This causes acetaldehyde to build up in the body as the liver attempts to create more glutathione, allowing the toxin to sit in the body for long periods of time, causing damage.
Your body can counter this toxin why cysteine which can be found in eggs and in supplements. Reducing your hangover symptoms.
