Excessive alcohol intake increases your susceptibility to cancers, liver disease, pancreatic disease and heart disease, according to health experts.
Alcohol also affects cognitive behavior associated with the frontal lobes of the brain. Excessive consumption can lead to a slowed processing of information, difficulty learning new material and reduced problem-solving abilities.
In fact, researchers have discovered that the brains of alcoholics are smaller than those of non-alcoholics and show evidence of substantial brain tissue loss.
"By weakening your immune system and impairing your cognitive abilities, alcohol can lead to premature illnesses - and an increased susceptibility to things like heart disease and early memory loss," said Samuel Bork, M.D., a general practitioner in Marin County, Calif.
However, recent studies have suggested that dark beer and red wine can fight free radicals, which increase in number when the body starts to metabolize food. Experts have said that the moderate consumption of beer and wine can be helpful in reducing the risk of heart disease and inflammation because they contain antioxidant flavonoids.
"It's a lesson that anything in moderation is fine - and just might be good for you," Bork said.
