Beer And Yeast Overgrowth: Is There A Link?

Candida is a naturally occurring yeast species, a type of fungus, that lives in the human body in small amounts. It is a normal part of the body's microflora and aids with digestion and nutrient absorption. However, when Candida begins to grow uncontrollably, it can cause an infection known as Candidiasis, which is the most common cause of fungal infections in humans. One of the major issues with Candida infections is the amount of live yeast in beer. Although most alcoholic drinks are fermented products, meaning most of the yeast is converted to alcohol, this is not the case with beer. Beer often contains much of the live yeast, which can add to the excess yeast already present in the gut, leading to an overgrowth. In addition, the sugar content in beer can feed the yeast, further contributing to the overgrowth. As such, drinking beer can indeed be a factor in causing yeast overgrowth in the body.

Alcohol and Candida create a perfect storm in the gut

Alcohol consumption plays a significant role in promoting Candida overgrowth. Firstly, alcohol weakens the immune system, disrupting the balance of good and bad bacteria in the gut, where a large portion of the immune system resides. This imbalance gives Candida the opportunity to proliferate. Additionally, alcohol damages the liver, which is responsible for filtering out toxins, including those produced by Candida cells, such as acetaldehyde. The accumulation of acetaldehyde can lead to toxicity and distort mental perceptions.

Furthermore, alcohol stresses the adrenal glands, which play a crucial role in regulating bodily processes and fighting Candida. Drinking alcohol lowers blood glucose levels, prompting the adrenal glands to produce the stress hormone cortisol. This exhausts the adrenal glands and can lead to hormonal imbalances. Alcohol also has a destabilizing effect on blood glucose levels, causing short-term spikes that encourage the growth of pathogens like Candida. The swings in glucose levels deplete the adrenals and the hypothalamic-pituitary-adrenal (HPA) axis, leading to cravings for sugar and fatty foods.

Additionally, alcohol is a fermented food, providing a direct source of fuel for Candida. All yeasts, including Candida, require sugar to thrive, and alcohol fermentation provides them with ethanol, their preferred energy source. Alcohol also injures the mucosal membrane, allowing Candida to grow deeper into the tissues, and interferes with nutrient absorption, potentially leading to nutrient deficiencies that further contribute to Candida overgrowth.

In summary, alcohol consumption and Candida overgrowth create a vicious cycle in the gut. Alcohol weakens the immune system, damages the liver, stresses the adrenal glands, and provides fuel for Candida, all of which contribute to the overgrowth of this yeast species. The resulting Candida overgrowth further compromises the gut, leading to digestive issues, fatigue, brain fog, and other health problems. Therefore, avoiding alcohol is crucial in managing and treating Candida overgrowth.

Alcohol weakens the immune system

Drinking alcohol weakens your immune system, leaving your body vulnerable to infections and increasing the chances of long-term illness. According to the National Institute of Alcohol Abuse and Alcoholism (NIAAA), even a single episode of binge drinking can leave you at higher risk of infection for up to 24 hours.

The immune system is the body's defence mechanism against infections caused by harmful bacteria and viruses. However, like a muscle, it can become weak if not properly cared for. Unhealthy habits such as stress, smoking, and excessive alcohol consumption can compromise the immune system's ability to protect the body.

Alcohol consumption alters the composition of the gut microbiome, which is home to trillions of microorganisms that play vital roles in maintaining health. It disrupts the balance of good and bad bacteria, creating an environment conducive to the overgrowth of opportunistic pathogens like Candida. This imbalance in the gut microbiome, where 80% of the immune system resides, hinders the body's ability to defend itself effectively.

Additionally, alcohol damages the protective lining of the respiratory tract, which is a crucial defence mechanism employed by the immune system to prevent upper respiratory tract infections. The respiratory tract is our body's first line of defence against pathogens, and alcohol compromises its integrity, making it easier for harmful microorganisms to enter the body.

Furthermore, alcohol consumption can lead to liver damage. The liver is responsible for filtering toxins from the bloodstream, including alcohol. Excessive alcohol intake can overwhelm the liver, impairing its function and creating a cascade of adverse effects on the body's ability to fight off infections.

In summary, alcohol consumption, especially in excessive amounts, weakens the immune system by disrupting the gut microbiome, damaging the protective linings of the respiratory tract and gut, and impairing liver function. These effects create an environment where opportunistic pathogens can thrive, leading to an increased risk of infections and long-term illnesses. Therefore, it is essential to drink in moderation or abstain altogether to maintain a robust immune system.

Alcohol damages the liver

There are several types of alcohol-associated liver disease, including steatotic (fatty) liver, acute hepatitis, and cirrhosis. Steatotic liver is the most common alcohol-induced liver problem, caused by a build-up of fat inside the liver cells, which leads to an enlarged liver. Alcohol-associated hepatitis is an acute inflammation of the liver, resulting in the death of liver cells and permanent scarring. Cirrhosis is the destruction of normal liver tissue, leaving scar tissue in its place. This can cause the liver to stop working correctly.

The effects of alcohol on the liver depend on how much and how long a person has been drinking. Alcohol-related liver disease (ARLD) usually doesn't cause any symptoms until the liver has been severely damaged. When this happens, symptoms can include jaundice (yellowing of the skin and eyes), swelling in the ankles and tummy, confusion or drowsiness, and vomiting blood or passing blood in stools. ARLD is often diagnosed during tests for other conditions or at a late stage of liver damage.

The treatment for ARLD is to stop drinking alcohol completely, preferably for the rest of the person's life. This allows the liver to recover and reduces the risk of further damage. In some severe cases, a liver transplant may be required if the liver has stopped functioning and does not improve with alcohol abstinence.

It's important to note that alcohol consumption can also have other negative effects on the body, including disrupting the balance of gut bacteria and weakening the immune system, which is mostly located in the gut. Additionally, alcohol can stress the adrenal glands, affect blood glucose levels, and feed Candida overgrowth in the gut.

Alcohol stresses the adrenal glands

Drinking large quantities of alcohol lowers blood glucose levels. As sugar levels drop, your adrenal glands produce the stress hormone cortisol. Cortisol raises your blood glucose levels, which exhausts your adrenal glands. Optimal adrenal gland function is essential for making hormones that regulate metabolism and communicate with other organs such as your brain, kidneys, and reproductive system.

Drinking alcohol affects the production of cortisol. Your adrenal glands naturally produce cortisol in response to different circumstances, such as waking up in the morning, exercise, anxiety, and stress. This is a healthy hormone production that helps regulate your blood pressure, sleep, metabolism, and overall immune response. Continuous drinking over an extended period has been shown to disrupt this natural production and raise cortisol levels in the body. It is thought that this happens because alcohol affects the brain chemicals that signal to the adrenals to produce more cortisol. Research has found that sudden alcohol withdrawal has the same danger. Periods of alcohol abstinence are characterized by increased activity of the adrenal glands, and sympathetic nervous system. This shows up as a collection of adrenal fatigue symptoms such as anxiety, excessive sweating, rapid heartbeat, and increased blood pressure.

A 2010 study showed that stress is a significant contributor to uncontrolled drinking, relapse, and withdrawal. In other words, we turn to alcohol to reduce stress, but it simply increases it by raising cortisol levels. If we try to “quit,” the body also reacts with a heightened stress response because of the sudden abstinence. Essentially, alcohol negatively influences the HPA axis and cortisol production. And the more you go through the start-and-stop cycle, the greater the neurological damage.

Drinking alcohol consistently can also increase the duration and intensity of your adrenal fatigue symptoms. While it’s supposed to make you feel drowsy and relaxed, excessive alcohol actually increases your brain’s activity—but at all the wrong times and in all the wrong ways. Even if it helps you fall asleep “quicker,” you won’t stay like this for long. Alcohol interrupts the REM stage of the sleep cycle. This is our restful, dream-state that we need to feel mentally refreshed and restored again. It’s why so many people experience a “hangover” the next day.

Alcohol can cause dysbiosis

When you drink alcohol, it enters your gut and disrupts the balance of good and bad bacteria, creating an environment conducive to Candida overgrowth. Additionally, alcohol can damage the liver, which is essential for filtering out toxins, including those produced by Candida cells. The liver metabolises alcohol into carbon dioxide and water, but this process can be overwhelmed if alcohol intake is high. As a result, the liver may struggle to process acetaldehyde, a toxic by-product of Candida overgrowth, leading to a buildup that can cause damage to the intestinal wall and result in "leaky gut syndrome".

Alcohol also stresses the adrenal glands, which play a crucial role in maintaining immune function and regulating metabolism. Drinking large amounts of alcohol lowers blood glucose levels, prompting the adrenal glands to release the stress hormone cortisol to raise blood sugar levels. This process fatigues the adrenal glands and can have detrimental effects on the body's ability to regulate metabolism and communicate with other organs.

Furthermore, alcohol consumption can destabilise blood glucose levels. While alcoholic beverages high in sugar can cause a short-term spike in blood glucose, they can also lead to significant swings in glucose levels, depleting the adrenals and the hypothalamic-pituitary-adrenal (HPA) axis. These fluctuations can trigger cravings for sugar and fatty foods, providing more fuel for Candida overgrowth.

Alcohol is also a fermented food, and all yeasts, including Candida, require sugar to thrive. When consumed, alcohol feeds Candida and contributes to its growth. Candida can utilise alcohol as an energy source and convert it into acetaldehyde, a compound that can cause toxicity and distort mental perceptions. Even small amounts of alcohol can be detrimental, and there is no known safe level of alcohol consumption when it comes to Candida overgrowth.
