Wheat Beer And Stomach Issues: What's The Link?

Many people enjoy a few beers with friends, but for some, wheat beer can cause stomach pain and discomfort. While moderate consumption is usually well-tolerated, beer has the potential to irritate the stomach or trigger or worsen a pre-existing condition. There are several reasons why wheat beer may upset your stomach. Firstly, it is often thought that wheat beer causes gas due to its high fibre content. However, the fibre in wheat beer is soluble, meaning it dissolves in water and is not fermented by the body, so it does not actually cause gas or bloating. Instead, the fermentation process breaks down carbohydrates, making wheat beer easier to digest than other types of beer.

Another reason wheat beer may cause stomach upset is related to its carbonation. Carbonated drinks, including wheat beer, can cause bloating, and the release of carbon dioxide gas during digestion can contribute to excess gas and bloating. Additionally, the presence of yeast in wheat beer can lead to yeast overgrowth in the intestinal tract, resulting in further bloating and gas.

Furthermore, some individuals may have a sensitivity or intolerance to the ingredients in wheat beer. While true food allergies are less common, sensitivities or intolerances can result in digestive problems like gas, bloating, diarrhoea, and abdominal pain. It is also possible to develop an allergy to wheat or barley, which are common ingredients in beer, and this could explain why wheat beer upsets your stomach.

Finally, excessive consumption of wheat beer can have more serious health consequences, including liver disease, pancreatitis, and certain forms of cancer. Therefore, if wheat beer frequently causes stomach upset, it is important to consult a doctor to rule out any serious underlying conditions and to discuss strategies for managing the discomfort.

Wheat beer's soluble fibre

Wheat beer is a desirable source of quality soluble dietary fibre (SDF). The consumption of beer in moderate amounts can have a positive impact on human health. The fibre content in beer is composed mainly of indigestible carbohydrates, with small amounts of polyphenolic compounds and indigestible protein.

Soluble fibre has been shown to reduce glucose and cholesterol levels and is, therefore, considered to have a protective role against heart disease and diabetes. The consumption of wheat beer can contribute to the intake of soluble fibre, which can provide benefits such as improved intestinal health and reduced risk of cardiovascular disease.

The effects of wort preparation parameters on the composition of soluble dietary fibre in wheat beer have been investigated. The wheat malt percentage (WMP) influences the content of non-starch polysaccharides and polyphenols, while extending the resting time at 63°C augments the resistant protein (RP) content. Optimised parameters for high SDF wheat beer include a WMP of 55%, resting for 20 minutes at 43°C, 20 minutes at 50°C, and 20 minutes at 63°C, resulting in an SDF content of 2,178 mg/L.

It is important to note that the consumption of wheat beer or any other alcoholic beverage should be in moderation as part of a balanced diet. Additionally, individual sensitivities or intolerances to specific ingredients in wheat beer may exist, and it is always best to avoid consumption if negative reactions occur.

Wheat beer's fermentation process

Wheat beer is a top-fermented beer brewed with a large proportion of wheat relative to the amount of malted barley. The two main varieties are German Weizenbier and Belgian witbier, with other types including Lambic, Berliner Weisse, and Gose.

The German Weizenbier, or Hefeweizen, is a wheat beer traditionally from Bavaria, introduced in the 15th century. It is brewed with a significant proportion of malted barley replaced with malted wheat. By law, Weizenbiers brewed in Germany must use a "top-fermenting" yeast. These specialised strains of yeast produce overtones of banana and clove as by-products of fermentation. The Hefeweizen style is also noted for its low hop bitterness and relatively high carbonation, balanced by the beer's malty sweetness.

Belgian witbier, or simply wit, is a barley/wheat, top-fermented beer. It gets its name from the suspended yeast and wheat proteins, which cause the beer to look hazy or white when cold. Witbiers usually contain flavourings such as coriander, orange, and bitter orange.

Bavarian wheat beers typically consist of 50% wheat and 50% barley. The difference in the type of yeast used is significant. A traditional Bavarian-style yeast strain gives the beer a rich and complex flavour and aroma. In the United States, a standard ale yeast is used, resulting in a lighter, almost bland flavour.

The fermentation process for wheat beer involves milling the wheat with a finer setting than barley, as wheat kernels are smaller and denser. The temperature for fermenting wheat beer is ideally around 70° F, with a range from 68° to 72° F. The warmer the beer is fermented, the more esters are produced.

Wheat beer intolerance

Symptoms of Wheat Beer Intolerance:

People with wheat beer intolerance typically experience a combination of symptoms, which may include nausea, vomiting, diarrhoea, abdominal pain, bloating, and gas. Less common symptoms can include hives, sneezing, wheezing, fatigue, anxiety, swollen lymph nodes, headaches, skin rashes, and puffy eyes. These symptoms can range from mild discomfort to more severe reactions, and they usually occur within a few hours of consuming wheat beer.

Causes of Wheat Beer Intolerance:

The specific cause of wheat beer intolerance can vary from person to person. In some cases, individuals may have a sensitivity or intolerance to one or more ingredients commonly found in wheat beer, such as grains, hops, yeast, or specific additives. For example, some people may be intolerant to wheat or gluten, which is often present in wheat beers. Additionally, the fermentation process and carbonation in wheat beer can contribute to digestive issues, especially for those with yeast sensitivities.

Diagnosis and Management:

If you suspect wheat beer intolerance, it is recommended to consult a doctor or a healthcare professional. They can help determine whether the symptoms are due to an intolerance, allergy, or another underlying condition. Keeping a food diary and tracking your symptoms can be helpful in identifying triggers.

The best strategy to manage wheat beer intolerance is to avoid consuming wheat beer or other alcoholic beverages that trigger similar symptoms. Switching to gluten-free drinks like cider or wine, or trying gluten-free beer options, may be suggested. Additionally, drinking in moderation, drinking slowly, and consuming food along with alcoholic beverages can help reduce the severity of symptoms.

Wheat beer allergy

Allergies occur when the body's immune system identifies a certain substance as harmful and overreacts to it. In the case of wheat beer, people may be allergic to specific ingredients such as wheat, barley, gluten, yeast, or hops. True allergies can cause symptoms such as hives, itching, swelling, abdominal pain, chest tightness, and in severe cases, anaphylaxis. Anaphylaxis is a life-threatening reaction that requires immediate medical attention and includes symptoms such as loss of consciousness, severe itching, and difficulty breathing.

On the other hand, food intolerances and sensitivities are more common and are related to the digestive system's response to certain substances. They typically cause less severe symptoms, such as gas, bloating, diarrhoea, constipation, cramping, and nausea.

If you suspect you have a wheat beer allergy, it is important to consult a doctor or allergist. They can perform skin and blood tests to determine if you have an allergy and identify the specific allergen. Keeping a food and symptom diary can also help identify patterns and trigger factors.

The best way to manage a wheat beer allergy is to avoid drinking wheat beer or any products containing the specific allergen. With research and careful label reading, you may be able to find alternative beers that do not contain the allergen.

It is worth noting that allergies can develop at any time, and even if you have been drinking wheat beer without issues, you may develop an allergy or intolerance later on.

Wheat beer and gastritis

Wheat beer is often thought to cause gas and bloating, but this is a misconception. Wheat beer is high in fibre, but the fibre in wheat beer is soluble, meaning it dissolves in water and is not fermented by the body. This means it won't cause gas or bloating. The fermentation process in wheat beer also breaks down carbohydrates, making them easier to digest.

However, wheat beer, like other beers, contains carbonation, which can cause bloating. Beer is also made up of grains, hops, and yeast, which can be difficult for some people to digest and can cause an allergic reaction. Beer allergies can cause symptoms such as hives, nausea, abdominal pain, and diarrhoea.

If you experience stomach pain and discomfort after drinking wheat beer, it could be a sign of gastritis or peptic ulcer. Gastritis is an inflammation and irritation of the stomach lining, with symptoms including abdominal pain, nausea, and vomiting. Reactive gastritis is often caused by chemicals or excessive alcohol. A peptic ulcer is an open sore in the stomach lining, usually caused by bacterial infection or overuse of certain drugs. While a peptic ulcer is not caused by alcohol, consuming excessive alcohol can interfere with ulcer healing and worsen existing stomach damage.

If you experience frequent stomach pain after drinking wheat beer, it is important to consult a doctor to rule out any serious underlying conditions.
