Hair zinc and copper in chronic alcoholics.

ABSTRACT

Chronic alcoholics frequently show associated malnutrition. Both ethanol and malnutrition exert profound changes on zinc and copper metabolism. In this study, we found higher hair zinc and copper values in 43 male alcoholics than in 39 controls. Hair copper was significantly related to the amount of ethanol consumed, whereas hair zinc was higher in consumers of distilled beverages. No relation was observed between hair zinc and copper and nutritional status, kind of diet consumed, style of life, and liver cirrhosis. Consequently, hair zinc and copper levels are related only with alcohol intake.
