The numerous studies found that beer just like wine has benefits for people’s health. The study carried by the Emory University discovered that those men and women who consumed minimum 1.5 drinks a day had 50 percent less risk of heart attacks.
Another study involving German, France and the United Kingdom discovered that restrained consumption of beer or wine lowers the risk of coronary heart disease. It is enough to just take a look at French who are addicted wine drinkers- there is one of the lowest rates of coronary heart diseases in this country.
Beer also positively affects the brain functioning. Scientists from Boston found that light drinkers (consume up to six drinks weekly) and moderate drinkers (consumer from seven to fourteen drinks weekly) were observed to have less strokes than nondrinkers as alcohol prevents the blood thinning and blood clots formation in the brain. But as for the heavy drinkers (consume more than fifteen drinks weekly)- despite having less strokes, they suffer from atrophy and brain tissues wasting.
The reasonable amounts of alcohol leads to stress reducing, nervousness and anxiety decreasing and mood improving. Actually, beer is rich with nutrients including protein, B vitamins, phosphorus, magnesium, selenium, iron, niacin and riboflavin.
But one shouldn’t be thinking that drinking beer brings only benefits. The health risks connected to drinking larger amounts of alcohol are more significant than benefits. One of the most significant harm of alcohol is its destructive effect on the liver. Liver is responsible for toxins removing from the body. Enzymes in liver first transform alcohol into acetaldehyde, which are the chemical intermediates that can initiate nausea, headache and vomiting. The molecule called NADH is also created during this step.
Acetaldehyde is further converted into acetic acid and later into water and carbon dioxide that we exhale. But bodies of those people who consume alcohol often are not able to metabolize the toxic acetaldehyde quickly enough. Besides, heavy drinkers have the higher levels of NADH, which leads to fat accumulation in the liver known as “Fatty liver”. This fatty liver is not only less effective in carrying its main duties, but can also prevent normal distribution of oxygen and nutrients to the liver cells. Thus, these liver cells die and form fibrous scar tissue that causes cirrhosis and liver scarring. This condition is considered to be potentially deadly.
Another negative effect of the high level of NADH- development of free radicals, which are harmful and may cause liver cells damage. Besides that, beer has a great amount of calories that can transfer into obesity, which is the main cause for heart disease and diabetes.
