I have extremely high cholesterol. Which alcohol is the safest for me to drink?

Alcohol? If u want a good answer , none . Eat fruit , vegetable and exersize.
It depends. Total cholesterol doesn't tell me enough. If your LDL or HDL is very high, then alcohol has little impact (in reasonable amounts). If it is the triglycerides that are high, then all/any alcohol is likely a problem. However, you should really talk to a clinical lipidologist (special cholesterol dr.) for help, visit www.Lipid.Org and look for a board certified lipidologist near you.
Cholesterol. No alcohol is safe but not contraindicated. Red wines has some support for cholesterol lowering.
