Alcohol Awareness - Rethinking your Drinking!
Article written by Germaine Guzman.
Alcohol Awareness Month runs from April 1st to April 30th and it’s a good a time as any to take a closer look at alcohol and perhaps your drinking habits too! The word ‘alcohol’ often conjures up visions of delicious cocktails, parties, food, letting your hair down and perhaps the grueling hangover! It’s safe to say that alcohol is both a tonic and a poison.
Almost half of Americans aged 12 or older reported being current drinkers of alcohol in a 2001 survey (48.3 per cent). This translates to an estimated 109 million people. Both the rate of alcohol use and the number of drinkers increased from 2000, when 104 million, or 46.6 per cent, of people aged 12 or older reported drinking in the past 30 days.6
What is alcohol and how is it metabolized?
The active ingredient in alcoholic beverages is a simple molecule called ethanol which affects the body in many different ways.3 It also contributes calories, 1 gram of alcohol providing 7 calories! 60 – 90 % of ethanol metabolism occurs in the liver but a small proportion of alcohol is also metabolized by the stomach. Ethanol is rapidly absorbed, primarily in the upper gastrointestinal tract, and appears in the blood in as quickly as 5 minutes after ingestion. The rate at which alcohol disappears from the blood varies from 6 to 10g per hour.2
Food in the stomach will delay the absorption of alcohol and will reduce alcohol blood concentration levels.2 This is why the saying goes, “do not drink on an empty stomach!” The types of food eaten with alcoholic beverages will also alter blood alcohol levels. Studies show that meals rich in fat, carbohydrate and protein result in average alcohol concentration levels.2
So what exactly is the harm?
Alcohol directly influences the stomach, brain, heart, gallbladder and liver. It also affects levels of lipids (bad cholesterol) and insulin in the blood, as well as inflammation and coagulation.3 So too much is not good news! Although moderate alcohol use may have some health benefits, they are outweighed by greater risks such as:
- Cardiovascular system- Alcohol can raise high blood pressure and bad cholesterol which causes damage to the heart muscles and strokes.1
- Nervous system- Such as brain damage, tremors, dementia and nerve damage. Alcohol is a depressant drug and affects coordination, self-control, judgment and reaction times.1
- Gastrointestinal system- Can cause stomach inflammation and bleeding.4
- Liver- Cancer, hepatitis, fatty changes, cirrhosis and liver failure.4
- Endocrine system- Can cause problems developing blood sugar, loss of libido and reduced fertility.4
- Nutrition- Malnutrition can occur (alcohol displaces nutrients from your body) and excessive alcohol intake can contribute to obesity.4
- Breast cancer and other gynecological problems- Women who drink alcohol are at a higher risk of developing these problems than non-drinking women.4
- Accidents, Injury and Violence- This includes motor vehicle accidents, falls, fires and all forms of violence such as domestic violence and sexual assault.4
How much is too much?
In some studies, the term ‘moderate drinking’ refers to less than one drink per day, while in others it means three or four drinks per day. In the U.S., one drink is usually considered to be 12 ounces of beer, 5 ounces of wine, or 1 ½ ounces of spirits (hard liquor such as gin or whisky). Each delivers about 12 to 14 grams of alcohol.3, 5 The latest consensus places this point at no more than one to two drinks per day for men, and no more than one drink per day for women. This is the definition used by the U.S. Department of Agriculture and the Dietary Guidelines for Americans and is widely used in the United States.3
Sometimes even a little is too much….
Even moderate levels of drinking (up to 2 drinks per day for men and 1 for women) can be too much in some circumstances. It’s safest to avoid alcohol if you are:
- Under the age of 217
- Pregnant, breastfeeding, or trying to fall pregnant1
- Planning to drive a car or use machines (more than 16,000 people die each year in automobile accidents in which alcohol is involved!)1, 3
- Taking over-the-counter or prescription medicine that can interact with alcohol4
- Recovering from alcoholism7
Possible health benefits of alcohol
But it’s not all doom and gloom! ‘Moderate’ alcohol consumption may provide some health benefits which include:
- Reducing the risk of Cardiovascular Disease4
- Reducing the risk of Peripheral Arterial Disease 4
- Reducing the risk of Ischemic Strokes4
- Lowering the risk of developing Type 2 Diabetes4
- Lowering the risk of developing Gallstones4
Taking Action!
Small changes can make a big difference in reducing your chances of having alcohol-related problems. Here are a few tips and strategies on how to drink responsibly and to help you cut down on the drink:
- Eat before and while drinking to slow the absorption of alcohol into your bloodstream.1
- Avoid salty snacks that make you thirsty and make you drink more.1
- Pace yourself and sip slowly. Make every other drink a non-alcoholic one, such as water, soda or juice.5
- Try low alcoholic drinks.1
- Always keep your drink with you to minimize the risk of drink spiking.1
- Keep track of how much you drink. Making a note of each drink before you drink it may help you slow down when needed.5
- Find alternatives. If drinking has occupied a lot of your time, develop new and healthy activities, hobbies and relationships to keep you busy.5
- Avoid ‘triggers’. If certain people or venues make you drink, even when you don’t wish to, try to avoid them.5
- Learn when to say ‘no’. When offered a drink when you don’t want one, be prepared to politely decline the offer. The faster you can say no, the less likely you are to give in.5
- Social and professional support. Don’t be afraid to ask for help!5
The bottom line is to balance the risks and the benefits. While excessive alcohol consumption has been linked to a number of serious health and social problems, moderate alcohol consumption has been associated with some health benefits. Above all, never feel pressured to drink. If you do enjoy the occasional drink and you’re healthy, there’s no need to stop as long as you drink responsibly and in moderation.
