See http://www.findarticles.com/cf_dls/m.../article.jhtml or search google.
A quote:
Quote:
When a person drinks alcohol, two different enzymes in the liver break it down, first into acetaldehyde and then into acetate. People with a shortage of the second enzyme, aldehyde dehydrogenase-2 (ALDH-2)--which is normally detected in blood and saliva--can't break down acetaldehyde efficiently.
...
Among Asians, 2 percent of people carry a genetic mutation that causes them to totally lack ALDH-2. In nearly all cases, these people can't drink alcohol because it makes them flushed, dizzy, and nauseated.
Many other Asians, including nearly half of the Japanese population, have a milder form of the mutation. These people produce some ALDH-2 but typically less than one-third the normal amount. They have less severe reactions to alcohol than people without any ALDH-2.
