Beer, when consumed in moderation, does not pose a significant health risk, and research has shown that it can increase the diversity of gut microbiota. However, for some people, beer can actually be toxic. Those with certain conditions should avoid beer. Here, we explore the representative diseases for which beer should be avoided and the reasons why.
◆ Irritable Bowel Syndrome
A cold beer can actually irritate the intestinal mucosa. While it may not be a major issue for healthy individuals, it can exacerbate symptoms such as abdominal pain, bloating, and diarrhea in patients with irritable bowel syndrome. Even if you crave a cold beer, it is advisable to avoid it if you have irritable bowel syndrome.
◆ Diabetes
Beer is an alcoholic beverage made by fermenting grains, and even without added sugar, its high carbohydrate content can rapidly raise blood sugar levels. Alcohol can also promote insulin secretion when consumed on an empty stomach, increasing the risk of hypoglycemic shock. For diabetes patients, moderate drinking is possible if blood sugar is well controlled, but distilled spirits like soju or whiskey, which have lower sugar content, are preferable to brewed beverages like beer, wine, or makgeolli.
◆ Gastroesophageal Reflux Disease
If you frequently experience heartburn or acid reflux, it may be worth considering gastroesophageal reflux disease. This condition is sensitive to acidic foods and beverages, so it is advisable to avoid sour orange juice and tomato juice. Caffeine and fatty foods can also exacerbate symptoms. Additionally, alcohol, especially beer, should be approached with caution. Alcohol can relax the esophageal sphincter, which can worsen acid reflux.
◆ Liver Disease
In cases of chronic liver diseases such as hepatitis or cirrhosis, alcohol, including beer, can pose a deadly burden on the liver. Alcohol is detoxified in the liver, and an already damaged liver has reduced capacity for this function, leading to greater damage during the detoxification process. Ultimately, alcohol adds additional stress to an already weakened liver due to underlying conditions, potentially accelerating long-term liver function decline.
◆ Gluten Sensitivity
Beer typically contains gluten, so caution is necessary. If a person with celiac disease consumes beer, it can trigger an inflammatory response, leading to symptoms such as diarrhea, abdominal bloating, and skin rashes. In such cases, it is advisable to choose gluten-free beer. Last year, gluten-free beer was also launched in the domestic market, in addition to being non-alcoholic.
