Top 10 Foods that Cause Mucus Build Up : Those with Asthma and COPD Should Avoid Them

What is Mucus?

Before we dive into the list, let’s first understand what mucus is. Mucus is a thick, sticky substance that is produced by the body.

It plays an important role in protecting our respiratory system by trapping bacteria, viruses, allergens, and other particles. However, when the body produces too much mucus, it can lead to discomfort and respiratory issues.

The Role of Diet in Mucus Production

While mucus production is a natural bodily process, certain foods can stimulate the body to produce more mucus than necessary. These foods are typically ones that are high in fat, dairy, or sugar.

They can also be foods that you may have an allergy or sensitivity to. By avoiding or limiting these foods, you may be able to reduce the amount of mucus your body produces.

List of Mucus Forming Foods

Here are some common mucus forming foods that you may want to avoid or reduce in your diet:

Dairy Products

Dairy products like milk, cheese, and yogurt are known to be mucus forming. They contain a protein called casein, which can increase mucus production in some individuals.

If you notice that dairy products worsen your mucus congestion or respiratory symptoms, it may be best to limit your intake or try dairy alternatives.

Fried Foods

Fried foods, such as french fries, fried chicken, and fried snacks, can be mucus forming due to their high fat content.

These foods can be difficult for the body to digest, leading to increased mucus production. Consider opting for baked or grilled options instead.

Sugary Foods and Drinks

Sugar can contribute to inflammation in the body, which can lead to increased mucus production. Foods and drinks high in sugar, such as soda, candy, and pastries, can worsen mucus congestion. Choose healthier alternatives like fresh fruits or nuts instead.

Processed Foods

Processed foods often contain additives, preservatives, and artificial ingredients that can trigger an immune response and increase mucus production.

For example, processed meats like hot dogs and sausages can be mucus forming. It’s best to opt for whole, unprocessed foods whenever possible.

Wheat and Gluten

Some individuals may have a sensitivity or intolerance to wheat or gluten, which can lead to increased mucus production.

If you suspect that wheat or gluten may be contributing to your mucus congestion or other symptoms, try eliminating them from your diet for a period of time to see if there is an improvement.


Alcohol can dehydrate the body and cause inflammation, which can lead to increased mucus production. It can also impair the immune system, making it more difficult for your body to clear mucus. Limiting or avoiding alcohol may help reduce mucus production.

Cold Foods and Drinks

Cold foods and drinks, such as ice cream and cold beverages, can constrict blood vessels in the throat and respiratory tract, leading to increased mucus production. Opt for warm or room temperature foods and drinks instead.


Caffeine is a diuretic, which means it can dehydrate the body. Dehydration can thicken mucus, making it more difficult to clear. Limiting your intake of caffeine, such as coffee and energy drinks, may help reduce mucus production.

Spicy Foods

Spicy foods, like chili peppers and hot sauces, can cause your body to produce more mucus as a protective mechanism. If you’re already dealing with excess mucus, it may be best to avoid or limit spicy foods.

High Histamine Foods

Foods that are high in histamine, such as aged cheeses, fermented products, and cured meats, can trigger an allergic reaction and increase mucus production.

If you suspect that histamine-rich foods are contributing to your mucus issues, consider eliminating or reducing your intake of these foods.

Frequently Asked Questions (FAQs)

How long does it take for mucus to go away?

Mucus production is a normal bodily process, and the time it takes for mucus to go away can vary depending on the individual and the underlying cause. In most cases, mucus should clear up within a few days to a week. However, if you have persistent or chronic mucus issues, it’s best to consult with a healthcare professional.

Can mucus-forming foods cause allergies?

While mucus-forming foods may not directly cause allergies, they can trigger an immune response in individuals who are sensitive or allergic to certain foods. This immune response can lead to increased mucus production as the body tries to protect itself.

Are there any foods that can help reduce mucus production?

Yes, certain foods may help reduce mucus production. Foods with anti-inflammatory properties, such as ginger, garlic, and turmeric, can help reduce inflammation in the body, which can lead to decreased mucus production. Additionally, staying hydrated by drinking plenty of water can help thin mucus and make it easier to clear.


By being mindful of the foods you consume, you can take control of your mucus production and potentially reduce discomfort caused by excess mucus. Limiting or avoiding mucus forming foods, such as dairy products, fried foods, sugary foods, and processed foods, may help alleviate symptoms associated with increased mucus production.

Experiment with your diet and observe how certain foods impact your body to find what works best for you. Remember, everyone’s body is unique, and what works for one person may not work for another.
