BEER
The following study shows that beer mitigates some of the effects of copper
deficiency. Copper deficient rats given beer lived six times as long as copper
deficient rats given water. Interestingly, the effects were found to be
unrelated to the copper, chromium, and alcohol in the beer. My guess is that the
effect is due to the yeast which other studies show increases copper uptake in
the cells.

Beer mitigates some effects of copper deficiency in rats.
Klevay LM, Moore RJ
United States Department of Agriculture, Grand Forks Human Nutrition
Research Center, ND 58202.
Because of an epidemiologic association of decreased risk of death from
ischemic heart disease with moderate use of alcoholic beverages, and because
numerous abnormalities found in people with ischemic heart disease are also
found in animals deficient in copper, rats were fed a diet deficient in
copper and were given either beer or water to drink. Rats drinking beer
lived nearly six times as long and had lower plasma cholesterol, less
cardiac enlargement, and higher liver copper. Apparent absorption and
biological half-life of oral radiocopper were increased by beer. The effects
were not attributable to alcohol, chromium, or copper in beer. Beer intakes
were similar to those of some people in the United States. Results may
explain seasonal cycles in plasma cholesterol and may be germane to the
epidemiology of ischemic heart disease because diets in the United States
seem to be low in copper.
