Ethanol both "GOOD" & "BAD"

Ethanol, also called ethyl alcohol or grain alcohol, is present in varying amounts in beers and wines. It is also found in distilled liquors such as whisky, gin an rum. It is produced by the natural process of fermentation.

Alcohol mainly utilizes our body for heat production. It does not contain any amounts of vitamins and minerals and even acts to displace vitamins from our body causing the intestinal cells to stop absorbing thiamine and B12. Thus the balance of blood nutrients is disrupted.(ENVIRONMENTAL SCIENCE by Salvacion Dorado)
