Excess mucus production can be caused by underlying conditions such as asthma, chronic bronchitis, or cystic fibrosis, and certain foods are believed to be common offenders. Dairy products like milk and cheese are often thought to increase mucus production, but the evidence is limited. While some studies have found a link between milk consumption and mucus production, others have found no relationship between the two. It is important to note that mucus plays a crucial role in keeping our bodies healthy, and a certain amount is normal. However, if you experience excess mucus, it is recommended to keep a food diary and monitor your symptoms to identify any trigger foods or underlying conditions.

Dairy elimination diets can improve symptoms of asthma and respiratory tract mucus production
Dairy products, including milk and cheese, have long been associated with increased mucus production and asthma symptoms. However, the link between dairy consumption and mucus production is not fully understood and may not be a simple cause-and-effect relationship. While some people report improved asthma symptoms and reduced mucus production when following a dairy elimination diet, others find no significant change.
The belief that dairy products increase mucus production is widespread, and it is commonly recommended to reduce dairy intake when experiencing a cold or respiratory infection. However, scientific studies investigating this association have produced conflicting results. Some studies suggest that excessive milk consumption may stimulate mucus production in the respiratory tract, particularly in individuals with asthma or other respiratory conditions. On the other hand, other studies have found no significant link between dairy intake and mucus production or respiratory symptoms, even when participants were infected with a common cold virus.
One challenge in studying the dairy-mucus link is that expectations and beliefs can skew the results. People who believe that dairy products increase mucus production may adjust their dairy intake based on their symptoms, and their perceptions of thickened saliva or increased mucus may be influenced by their expectations. In one study, participants reported similar sensations of thickened saliva and a coating in the mouth and throat after consuming either cow's milk or soy milk, indicating that their expectations influenced their perceptions.
While the evidence for a direct causal link between dairy consumption and mucus production is limited, some individuals may still find relief from asthma and respiratory symptoms by reducing or eliminating dairy from their diet. It is important to note that a dairy elimination diet should be undertaken cautiously, especially in children, as it may lead to nutritional deficiencies and reduced calcium levels. If you are considering a dairy elimination diet, it is advisable to consult a healthcare professional to ensure that your nutritional needs are being met.

The belief that milk causes mucus production is widely held, but there is limited medical evidence
The belief that milk causes mucus production is a widely held one, but there is limited medical evidence to support this claim. Excessive milk consumption has long been associated with increased respiratory tract mucus production and asthma. However, this association cannot be explained by a conventional allergic paradigm, and there is little evidence of a causal relationship.
In the human colon, β-casomorphin-7 (β-CM-7), a substance derived from the breakdown of A1 milk, has been found to stimulate mucus production from gut MUC5AC glands. This substance may also stimulate mucus production in the respiratory tract, leading to conditions such as asthma, bronchitis, or cystic fibrosis. However, this hypothesis has not been extensively tested, and the published medical evidence documenting these links is limited.
Some studies have suggested that excluding milk products from the diet may improve asthma symptoms. For example, a study by Rowe and Rowe in the 1950s found that asthma patients' symptoms often improved on a diet excluding various foods, including milk. However, with the development of effective asthma medications, these observations were largely neglected. Another study by Pinnock et al. found that excluding milk from the diet improved symptoms of cough and nasal congestion.
It is important to note that mucus plays a crucial role in keeping our bodies healthy. It lines and protects our tissues, moisturizes, and traps things like dust, pollen, and mold. However, excess mucus can be an issue and may be caused by underlying conditions or dietary factors. If you are experiencing excess mucus production, keeping a food diary and monitoring your symptoms can help identify potential trigger foods and determine if an underlying condition is at play.
While the link between milk consumption and mucus production is not conclusively established, the impact of cheese, a dairy product, on mucus production is even less clear. Processed foods, in general, have been linked to mucus production due to the presence of common food additives. However, specific studies on the relationship between cheese consumption and mucus production are scarce.

β-CM-7, a compound in A1 milk, may stimulate mucus production in inflamed tissues
Mucus is important for the healthy functioning of the body. However, in excess, it can be an issue. Excess mucus production may be caused by underlying conditions or dietary factors.
Excessive milk consumption has long been associated with increased respiratory tract mucus production and asthma. This association may not be explained by a conventional allergic paradigm, and there is limited medical evidence of causality. However, studies have suggested that excluding milk products from the diet may improve asthma symptoms.
The protein β-casein, a major component of cow's milk, has two primary genetic variants: A1 and A2. The digestion of A1 β-casein yields the peptide β-casomorphin-7 (β-CM-7), an exorphin. β-CM-7 has been linked to an increased risk of cardiovascular disease, type 1 diabetes, and sudden infant death syndrome.
In the human colon, β-CM-7 stimulates mucus production from gut MUC5AC glands. This stimulation also occurs in inflamed respiratory tract tissues, leading to mucus overproduction, which is characteristic of many respiratory tract diseases. β-CM-7 from the bloodstream could stimulate mucus production in these respiratory glands. This hypothesis can be tested in vitro using quantitative RT-PCR to show that the addition of β-CM-7 increases MUC5AC mRNA expression in respiratory goblet cells.
In summary, β-CM-7, a compound derived from the breakdown of A1 milk, may stimulate mucus production in inflamed tissues. This effect is dependent on β-CM-7 passing into the systemic circulation and the presence of inflamed tissues. These factors may explain why only a subgroup of the population experiences increased respiratory tract mucus production and improved symptoms with a dairy elimination diet.

A food diary can help identify trigger foods that cause excess mucus production
Mucus is a gelatinous substance produced by the mucus membranes that line the mouth, nose, sinuses, throat, lungs, and gastrointestinal tract. It plays a crucial role in trapping dirt, dust, pollen, mold, bacteria, and viruses, preventing them from entering our bodies and causing harm. While some mucus is necessary for maintaining health, excessive mucus can lead to issues such as congestion, throat irritation, and respiratory problems.
Excessive milk consumption has long been associated with increased respiratory tract mucus production and asthma. This link is not fully understood and there is limited medical evidence to support it. However, it is believed that β-casomorphin-7 (β-CM-7), a compound derived from the breakdown of A1 milk, may stimulate mucus production in specific circumstances.
Cheese, as a dairy product, may also contribute to mucus production. Dairy contains casein, a protein that can trigger an inflammatory response and increase mucus secretion. Additionally, processed foods and snacks, including those with additives like sweeteners, preservatives, and thickeners, can interfere with intestinal mucus and lead to both under and overproduction of mucus.
To identify specific trigger foods, including those that may cause excess mucus production, maintaining a food diary is recommended by Harvard Health Publishing. By recording your dietary intake and monitoring any symptoms, you can potentially pinpoint certain foods that may be causing issues. This information can also be valuable to share with your doctor to determine if any underlying conditions or allergies are contributing factors.
In addition to identifying and avoiding potential trigger foods, incorporating mucus-regulating foods into your diet can be beneficial. Fresh garlic, ginger, pineapple, honey, and probiotic-rich foods like yogurt and fermented vegetables can all help support respiratory health and reduce excess mucus. Staying hydrated is also crucial, as water helps to thin out mucus and make it easier to clear from the airways.

Processed foods and food additives can cause mucus production and gut health issues
Mucus production is a natural bodily function that is essential for clearing our airways and keeping our lungs functioning properly. However, excessive or prolonged mucus production can lead to various respiratory issues, such as nasal congestion and chronic lung diseases. Certain foods can stimulate mucus production, and among them are processed foods and foods containing additives.
Processed foods, such as highly processed snacks and even processed forms of otherwise healthy foods like potatoes, can contain additives such as sweeteners, preservatives, and thickeners. These artificial ingredients have been linked to an imbalance in mucus production, leading to either excessive or insufficient mucus in the gut. This disruption in mucus homeostasis can result in an unhealthy gut environment, triggering harmful inflammatory responses or contributing to intestinal diseases.
In addition to the direct impact on mucus levels, the consumption of processed foods has also been associated with adverse effects on gut health. A diet high in ultra-processed foods can negatively affect the gut microbiome, leading to potential long-term consequences for overall health. The gut microbiome is a complex ecosystem of microorganisms that play a crucial role in maintaining digestive health, nutrient absorption, and immune function. Disruptions to this delicate balance can have far-reaching implications.
Furthermore, some processed foods can trigger histamine production or sensitivity in certain individuals. Histamine-rich foods or those that prompt the body to release histamine can stimulate mucus production, as suggested by the Annals of Dermatology. However, this is typically only a concern for people with histamine sensitivity or intolerance, which may be linked to enzyme deficiencies in the gut.
To maintain optimal respiratory and gut health, it is advisable to limit the consumption of processed foods and those containing additives. Instead, focus on incorporating more whole foods into your diet, such as garlic, ginger, pineapple, and fatty fish rich in omega-3 fatty acids. These natural foods possess anti-inflammatory and antimicrobial properties, helping to regulate mucus production and promote a healthier gut environment.

Frequently asked questions
Mucus is important for keeping your body healthy, but excess phlegm could be a result of an underlying condition or your diet. While there is limited medical evidence, excessive milk consumption has long been associated with increased respiratory tract mucus production. Cheese, like milk, is a dairy product, so it may have a similar effect on mucus production.
Other conditions like chronic bronchitis, asthma, and cystic fibrosis can cause excess mucus production in the long term. Irritable bowel syndrome and certain infections may also cause mucus to appear in your stool.
Keep a food diary and monitor your symptoms to help identify trigger foods. This can be helpful to show your doctor to determine if an underlying condition is at play.
Several small studies have found little to no link between milk consumption and mucus production. One study found that participants who believed milk made them produce more mucus reported more cough and congestion symptoms but did not produce higher levels of nasal secretions. Another study found no relationship between dairy intake and the weight of nasal secretions.
While cutting out dairy may help reduce mucus production, it is important to consider the potential risks, especially for children. For example, avoiding milk may expose children to problems caused by reduced calcium levels and restricted growth. It is best to consult with a doctor or healthcare professional before making any significant dietary changes.
