If you have elevated triglycerides and consume alcohol-a reduced intake or not drinking alcohol at all is strongly advised. Just one drink can increase triglycerides in susceptible people.Alcohol is a source of excess calories which are being turned into fat (usually, triglycerides), so the fat levels in your blood go up. But that is only part of the story.he liver can detoxify about one ounce of alcohol (distilled spirits) per hour, which is about 1 serving of an alcoholic beferage (equivalent to 12 ounces of beer or 4 ounces of wine). In the meantime, however, glucose tends to be further processed into triglycerides which raises their blood levels.
