Hundreds of studies conducted from the 1970s to modern day have shown time and again that moderate alcohol consumption decreases rates of cardiac mortality by about 25%. It was always assumed that this protective effect was balanced out by beer-induced weight gain and liver inflammation.
Instead, researchers from Spain have found just the opposite. These scientists were interested in the effects of beer on the development of Diabetes. They fed a group of males at high risk of developing Diabetes with either beer, gin, or non-alcoholic beer.
In line with the known effects of moderate consumption, these researchers found that alcohol was able to improve the balance of cholesterols in the body and reduce the factors that contribute to stiffening of the blood vessels, or atherosclerosis.
Unexpectedly, the researchers also found that a group of chemicals in beer, known as poly-phenols, reduced whole-body inflammation.
Specifically, the poly-phenols in beer lower levels of immune signals that cause the immune system to attack different parts of the body.
