Alcohol has some potentially positive benefits. Moderate alcohol consumption can be healthy, especially for the heart. Alcohol is a type of sugar—called an “alcoholic” sugar because it can only be broken down by enzymes in the human body when it’s combined with another substance, called an enzyme. This means that you cannot digest alcohol on its own. It turns out that the body can only digest certain kinds of alcohol and not others.
If a person drinks ethanol, it doesn’t stay in their system for very long, but if they drink methanol instead, the effects are quite different. The body digests ethanol quickly, so most of it leaves your system within one hour after drinking. However, because methanol does not get broken down as readily as ethanol does, its side effects last much longer than those of ethanol. Both types have their pros and cons—find out what they are below!
