Alcohol is deeply woven into societies and cultures around the world and is often present during life milestones and everyday moments, from toasts at weddings to happy hours after work, relaxation, and even rituals. While at times it can be harmless, the reality of its effects on health is complex, given its ability to contribute to addiction, impaired judgment, and long-term health risks. There has been increasing attention on the impact of alcohol on social and mental health, but also physical health and nutrition. People are often aware of the immediate effects, such as dehydration, altered mood, and perhaps a slight hangover; however, in this blog, we will explore how those effects show up in your day-to-day as alcohol interacts with dietary habits, metabolism, and long-term nutritional well-being. We are not here to demonize alcohol but rather to better understand its impact on the body and mind, and so you can make informed choices for your health and well-being.
What Happens In Your Body: How Alcohol Is Metabolized
Alcohol (or ethanol) is a chemical substance found in beer, wine, and spirits that has seven calories per gram; however, it does not provide any nutritional value to the body. When you consume alcohol, your body treats it as a toxin and prioritizes breaking it down to eliminate it as efficiently as possible. It starts with absorption in the lining of the stomach and small intestines, then into the bloodstream. It circulates through the body until eventually it reaches the liver, which is where alcohol is primarily metabolized. In the liver, enzymes convert ethanol into acetaldehyde and then into acetate. It is then broken down further into water and carbon dioxide to be eliminated. The body can typically process one alcoholic drink per hour. Any excess alcohol continues to circulate in the blood, affecting the brain, heart, and other organs. Because the body prioritizes the metabolism of alcohol, it interferes with the body’s normal use of carbohydrates, proteins, and fats.
Effects on Nutrition:
- Nutrient absorption: Alcohol can interfere with the absorption of essential vitamins and minerals by reducing the production of digestive enzymes and stomach acid, as well as damaging the lining of the stomach and intestines. As a result, this disrupts the digestive system and alters how the body processes and breaks down food to release the nutrients. The major nutrients affected by alcohol are vitamin B1 (thiamine), B12, folic acid, and zinc. These nutrients play major roles in brain health, nerve function, immune health, and metabolism.
- Gut microbiome: Alcohol can damage the gut microbiome as it tends to decrease the number and variety of healthy bacteria, all while promoting the growth of harmful bacteria. It irritates the gut lining, allowing toxins and bacteria into the bloodstream, and interferes with digestive enzymes. This imbalance in the microbiome (called dysbiosis) can trigger a range of digestive issues.
- Immune function: Even moderate alcohol intake can disrupt the normal activity of white blood cells (immune cells) that are essential for identifying and fighting off harmful bacteria and viruses. In addition to altering the gut microbiome, the damage to the gut lining can create what is known as “leaky gut”. This allows toxins and bacteria to enter the bloodstream more easily, triggering inflammation in the body. Chronic inflammation weakens the immune response and increases the risk of illness.
- Mental health: Alcohol can significantly impact mental health both in the short term and long term. While it may seem to initially relieve stress or anxiety, it is a depressant and disrupts the balance of neurotransmitters in the brain. These neurotransmitters include serotonin and dopamine. Chemicals that are responsible for regulating mood, motivation, and emotional stability. Drinking can lower the levels of these chemicals and contribute to depression, anxiety, irritability, and problems with memory.
- Athletic performance: Alcohol negatively affects athletic performance in several ways. First, it dehydrates the body and reduces blood flow and nutrient delivery to the muscles. This can lead to fatigue, cramps, and slower recovery. It also interferes with protein synthesis, impacting muscle repair, and lastly increases inflammation, making post-workout recovery less effective.
- Sleep: Alcohol may induce drowsiness and initially make falling asleep easier, so one might think it’s helping them sleep. However, when the body metabolizes alcohol during the night, it interferes with the natural sleep cycle, specifically REM sleep. REM is essential for cognitive function, memory, and emotional regulation. This results in less restorative sleep, which then leads to fatigue, irritability, and decreased concentration.
Can Alcohol Fit Into a Healthy Lifestyle?
Now knowing and understanding how alcohol is metabolized and how it not only affects mental health but also physical health, such as nutrient deficiencies, blood sugar imbalances, and increased fat storage, the question isn’t, is alcohol healthy? But rather, does it align with my health goals and well-being?
Mindful drinking is a conscious, intentional approach to drinking alcohol. Rather than drinking out of habit, social pressure, or emotional triggers, it simply asks you to pause, build awareness, and reflect. Why are you drinking? How does it make you feel? Does it align with your health and wellness goals? It doesn’t mean you are required to give up alcohol completely, but rather, allows you to set healthy boundaries with it. For example, maybe you only drink at social occasions or limit it to one or two drinks per occasion. It can also mean being present with the experience. For example, having a well-crafted drink where you can savor the flavors or choosing a glass of wine that pairs well with a meal.
A standard drink in the U.S. is defined as 0.6 ounces of pure alcohol, which equates to a 12-ounce beer, 8 ounces of malt liquor, 5 ounces wine, or 1.5 ounces of distilled liquor. The CDC recommends one drink or less a day for women and 2 drinks or less a day for men.
We do not encourage alcohol consumption even in moderation for certain populations, such as if you are pregnant or might be pregnant, under the age of 21 years old, have medical conditions directly impacted by alcohol, are taking medications that can interact with alcohol, or are recovering from addiction.
Maybe you think you want to go to social events and not drink, or simply reduce the amount. Here are some tips to try:
- Set intentions before you drink. Ask yourself why you’re drinking, how you want to feel physically and mentally during and after.
- Order or make a mocktail! Take a look at our website and Instagram for mocktail recipes we are currently loving!
- Alternate alcoholic drinks with water, especially if it’s an all-day event like a BBQ. This helps with giving your body time to metabolize the alcohol and also makes sure you are staying hydrated.
- Before drinking, always eat a balanced meal with protein, fiber, and healthy fats to help slow the alcohol absorption and maintain energy levels.
- Plan alcohol-free days and give your body regular breaks during the week.
Enjoying alcohol while trying to stay committed to your health goals can feel challenging, but it is possible. You don’t have to give up drinking entirely, however, it does require awareness, a realistic level of balance, and being intentional with your choices.
