While mucus is a natural substance found throughout the body, excessive production can cause discomfort and difficulties in breathing, vision, and digestion. Although excess mucus is often caused by illness or allergies, certain foods may also contribute to its production. Dairy products, such as cheese, have long been believed to cause high mucus levels, but the evidence is mixed. Some sources suggest that while dairy doesn't increase mucus production, it can cause it to thicken, leading to a feeling of congestion. Other studies have found no link between dairy and mucus secretion. In addition to dairy, other foods and beverages, such as sugar, alcohol, gluten, and greasy fried foods, have been associated with increased mucus production.

Dairy and mucus: Does cheese cause mucus?
Dairy and mucus have long been believed to have a connection, with many people assuming that dairy products like cheese and milk cause mucus buildup and congestion. However, according to several sources, including a July 2018 study in the BMJ, there is no evidence that dairy directly leads to increased mucus secretion.
The belief that dairy and mucus are linked is not unfounded, as drinking milk or consuming other dairy products can create a sensation of thickened phlegm or congestion. This is because the creamy, thick texture of dairy can mix with saliva in the mouth, creating a substance that feels similar to mucus. However, this thickness is temporary and does not indicate an increase in mucus production.
While dairy may not directly cause mucus buildup, it is important to note that individual sensitivities and allergies can play a role. Some people may have a dairy allergy, and while the most common symptoms include hives, throat and tongue swelling, and a drop in blood pressure, according to the Australasian Society of Clinical Immunology and Allergy (ASCIA), mucus production is not a typical symptom. Additionally, for people with asthma, drinking cold milk may trigger coughing due to the temperature irritating the airways, rather than a direct link between dairy and mucus.
If you are concerned about excess mucus or congestion, it is recommended to monitor your eating habits and identify any potential triggers. Sugar, greasy or fried foods, alcohol, and gluten are some common culprits that can contribute to increased mucus production. It is also beneficial to include plant-based foods and warm herbal teas in your diet, as they can help reduce respiratory issues and act as natural anti-inflammatories and decongestants.
In summary, while cheese and other dairy products may not directly cause mucus buildup, they can contribute to a sensation of thickened phlegm. Individual allergies and sensitivities can also play a role in how dairy affects mucus production. To manage excess mucus, it is advisable to avoid trigger foods and incorporate anti-inflammatory and decongestant foods into your diet.

Allergies and mucus: How are they related?
Mucus is a natural substance that lines the moist surfaces of the body, such as the lungs, sinuses, mouth, and eyes. It serves as a lubricant and a line of defence against dust, allergens, and microorganisms. While mucus is typically thin and clear when one is healthy, it can become thicker and darker in colour when one is exposed to smoke, allergies, or infections.
Allergies can indeed cause an increase in mucus production. Allergens such as pollen, pet dander, mould, and dust mites can trigger inflammation in the respiratory system, leading to increased mucus production. This allergy-induced mucus is often thick and sticky, causing post-nasal drip and potentially resulting in a chronic cough. The body's immune system overreacts to these allergens, releasing substances like histamine, which cause the mucous membranes to swell and produce more mucus.
Additionally, certain foods may contribute to excess mucus production. Greasy or fried foods, sugar, alcohol, and gluten are known to cause increased mucus levels. Dairy products, while once believed to directly increase mucus, are now understood to thicken existing mucus, leading to a sensation of congestion.
To alleviate allergy-related mucus, individuals can consider over-the-counter medications like expectorants, decongestants, and antihistamines. Warm herbal teas made with peppermint, licorice, or elderberry can also help soothe the throat and clear excess mucus. Plant-based foods containing quercetin, such as leafy greens and certain fruits, act as natural anti-histamines, reducing phlegm and allergy symptoms.
In summary, allergies and mucus are closely related, with allergens triggering increased mucus production and contributing to respiratory discomfort. While mucus is naturally produced by the body and serves important protective functions, allergies can cause an excessive and thickened state, leading to breathing difficulties and other symptoms. Understanding this relationship between allergies and mucus can help individuals manage their symptoms and make informed dietary choices to reduce the impact of allergies on their respiratory health.

Alcohol and mucus: What are the effects?
Alcohol consumption can have a range of effects on mucus production and the respiratory system. Alcohol can cause irritation in the throat and airways, leading to coughing as the body attempts to clear excess mucus. This is sometimes referred to as "alcohol cough". Certain alcoholic beverages also contain histamines and sulfites, which can trigger allergic reactions resulting in lung inflammation, shortness of breath, wheezing, and mucus buildup in the airways.
Heavy alcohol consumption can impair the function of cilia, the tiny hair-like structures that line the airways and help move mucus and other debris out of the lungs. This impairment, known as alcohol-induced ciliary dysfunction, can lead to a buildup of mucus and an increased risk of respiratory infections and other lung problems. Alcohol also has a dehydrating effect, which can increase the thickness of airway mucus.
Additionally, alcohol consumption can decrease the body's ability to fight off bacteria and airborne respiratory illnesses. It can also reduce the levels of protective antioxidants in the lungs, increasing the risk of severe injury and illness. Prolonged and heavy alcohol exposure may worsen lung function and outcomes in individuals with respiratory conditions such as asthma, bronchiectasis, and COPD.
The effects of alcohol on mucus production can vary between individuals, and not everyone experiences nasal congestion after consuming alcohol. However, for those prone to sinus congestion or with allergies, alcohol may exacerbate these issues. Alcohol causes blood vessels to constrict and dilate, leading to swelling in the nasal passages and contributing to congestion.
While cheese was once believed to cause high mucus levels, this is not entirely true. Although dairy may not directly increase mucus production, it can cause the mucus to thicken, contributing to a sensation of congestion and nasal blockage.
