Alcohol’s effect on the brain.

Thursday, January 14th, 2010

Anyone serious about craft beer should know that great beer should be enjoyed responsibly. Many of the most interesting and unusual beers out there frequently carry with them high alcohol percentages, some as high as 13 or 14%. Beer this strong can have a powerful effect on anyone. Today, we’re going to take a look at how alcohol affects the brain.

There are basically four stages of intoxication-

1st Stage – The first part of the brain alcohol hits is your cerebral cortex, making you more talkative and less inhibited. Because the cerebral cortex controls conscious thought, language and social interaction, these aspects of our personality begin to run less efficiently under the influence of alcohol.

2nd Stage – After the cerebral cortex, alcohol begins to affect the hippocampus, resulting in memory loss and exaggerated emotions. This is the part of the evening when you begin having trouble with balance and start telling everyone “I love you, man!” Due to the importance of the hippocampus in long-term memory retention, this is also when memory starts to get a little fuzzy.

3rd Stage – Next up on alcohol’s hit list is the  cerebellum, which seriously impairs your coordination and balance. This is not a pretty sight. The typical person usually has so much trouble keeping their balance at this point that they can no longer stand up. Nausea and vomiting frequently occur during this stage. Scientists believe that these symptoms stem from increased levels of acetaldehyde present in the body, a by product of metabolizing alcohol.

4th Stage – Finally alcohol makes it way to your medulla, frequently resulting in disruptions of automatic functions, like heart rate & breathing. This is serious and immediate medical attention should be sought. Usually a person is passed out at this point, and alcohol poisoning is a high risk.

As soon as you consume alcohol, your body begins breaking it down. Your liver metabolizes around 90% of the alcohol you consume. The remaining 10% is actually excreted through urine and breath, albeit at a much slower rate. The average liver can metabolize about 1 drink per hour. If you consume more than that, the liver can’t break the alcohol down fast enough, and you begin to get drunk.

Having some food with your beer can slow down the consumption rate, causing you to get less drunk, but it’s no excuse to drink excessively. Great beer should be enjoyed for its taste and merit, not as a way to get drunk. If you have concerns about your alcohol consumption or that of someone you know, the best idea is to consult a medical professional.

Drinking To Your Health: Beer And The Body

Today’s post is part 2 of Beeriety contributor Sarah’s look at beer and health. Thanks Sarah!

The health benefits of beer (when consumed in moderation, of course) are almost in-numerable. A beer can help with everything from settling an upset stomach to improving heart health to increasing blood iron levels. It can strengthen bones, improve skin, and defend against memory loss. And as for those beer bellies, it doesn’t cause them. What beer does do, as more and more evidence is suggesting, is just about everything that red wine does – maybe more!

The specific benefits of beer come from three main areas:

Alcohol: We’ve been hearing for years now that regular consumption of small amounts of alcohol is good for you. A drink a day can help increase blood flow, which is both relaxing and good for the heart, reducing the likelihood of stroke or heart attack. A lesser known benefit to drinking is its ability to fight osteoporosis. Because alcohol helps the body absorb calcium more efficiently it can help maintain healthy, strong bones. Low to moderate alcohol consumption has been loosely linked to fighting diseases and conditions like dementia, type 2 diabetes, hearing loss, rheumatoid arthritis, and ulcers. Those who drink a little live longer (and healthier) than those who drink too much or not at all. And a standard 12oz bottle of beer (typically) has the same amount of alcohol that a standard 5oz pour of red wine would have.

B-Vitamins: The grains and yeasts used to make beer are rich in powerful B-vitamins, which help the body maintain healthy metabolism, immune function, and red blood cell counts. And like alcohol, they’ve also been linked to improved blood pressure and healthy heart function. Most notably, the concentrations of B6, B12, and folic acid found in beer help prevent the build-up of homocysteine, an amino acid linked to both cardiovascular problems and bone-deficiency, making beer valuable to heart, bone and skin health.

Hops: Hops, as we’ve learned before, are a flowering plant used to balance the flavor of beer and help keep unwanted bacteria from affecting the desired reactions of the yeast. However, before it was used in beer, hops were used to treat everything from indigestion to leprosy. Today hops (when not in beer) are most frequently used as an herbal supplement to treat insomnia and mild anxiety. These anti-oxidant-rich plants contain a powerful compound called xanthohumol, a prenylflavonoid which may fight conditions like cancer and Alzheimer’s. While most beers only contain trace amounts of this compound (the hoppy-er varieties will obviously have more), hops have many other health benefits: they can reduce blood triglyceride levels; they can help sooth upset stomachs and aid in digestion; and they can help reduce the calcium build-up that leads to kidney stones. In addition, hops are a powerful phytoestrogen, potentially aiding in the fight against heart disease, certain cancers, and osteoporosis.

So, the next time someone tells you to put down the pint glass and pick up a wine glass, don’t be afraid to proudly defend your drink of choice!
