Mast cells are a type of immune system cell that play a crucial role in our body’s defense against infection and injury. However, in some individuals, mast cells can become overactive, leading to a range of symptoms including hives, itching, digestive issues, and even anaphylaxis. One of the key triggers for mast cell activation is food, and in this article, we will explore the foods that can trigger mast cell activation and provide guidance on how to manage mast cell symptoms through dietary changes.
Understanding Mast Cell Activation
Mast cells are found throughout the body, but are concentrated in areas such as the skin, lungs, and gastrointestinal tract. When mast cells are activated, they release a range of chemical mediators, including histamine, which can cause blood vessels to dilate, smooth muscle to contract, and mucous production to increase. In individuals with mast cell activation syndrome (MCAS), the release of these chemical mediators can lead to a range of symptoms, including:
- Hives and itching
- Digestive issues such as bloating, abdominal pain, and diarrhea
- Respiratory symptoms such as wheezing and shortness of breath
- Cardiovascular symptoms such as rapid heartbeat and changes in blood pressure
- Neurological symptoms such as headaches, fatigue, and brain fog
The Role of Food in Mast Cell Activation
Food can play a significant role in triggering mast cell activation, and certain foods are more likely to cause symptoms than others. Foods that are high in histamine, tyramine, and other biogenic amines are particularly likely to trigger mast cell activation. These foods include:
- Fermented foods such as cheese, wine, and beer
- Cured meats such as bacon and salami
- Fish such as tuna and mackerel
- Eggs
- Chocolate
- Citrus fruits such as oranges and lemons
- Tomatoes
In addition to these foods, some individuals may also experience mast cell activation in response to food additives such as:
- Monosodium glutamate (MSG)
- Aspartame
- Tartrazine
- Sodium benzoate
Other Dietary Triggers
In addition to foods that are high in histamine and other biogenic amines, other dietary triggers for mast cell activation include:
- Spicy foods, which can cause the release of chemical mediators from mast cells
- Foods that are high in sugar, which can lead to inflammation and oxidative stress
- Foods that are high in advanced glycation end (AGE) products, which can stimulate the release of pro-inflammatory cytokines
Managing Mast Cell Symptoms through Dietary Changes
While avoiding trigger foods can help to manage mast cell symptoms, it is also important to focus on incorporating foods that are rich in nutrients and antioxidants. These foods can help to reduce inflammation and oxidative stress, and may also help to stabilize mast cells and reduce the release of chemical mediators.

What is mast cell activation and how does it affect the body?
Mast cell activation is a condition where mast cells, a type of immune system cell, become overactive and release excessive amounts of histamine and other chemical mediators. This can lead to a range of symptoms, including hives, itching, flushing, digestive issues, and respiratory problems. When mast cells are activated, they can also contribute to chronic inflammation, which can exacerbate conditions such as arthritis, fibromyalgia, and irritable bowel syndrome.
The effects of mast cell activation can vary widely from person to person, depending on the individual’s sensitivity and the specific triggers involved. In some cases, mast cell activation can be a minor annoyance, while in others it can be a debilitating condition that significantly impacts daily life. Understanding the foods that trigger mast cell activation is an important step in managing the condition and reducing symptoms.
What are some common foods that trigger mast cell activation?
Some common foods that trigger mast cell activation include fermented foods, such as sauerkraut and kimchi, which contain high levels of histamine. Other culprits include citrus fruits, tomatoes, and spicy foods, which can stimulate mast cell release. Foods high in tyramine, such as aged cheeses and processed meats, can also trigger mast cell activation. Additionally, some people may react to foods containing sulfites, such as wine and processed snacks.
It’s worth noting that everyone’s triggers are different, and what causes mast cell activation in one person may not affect another person in the same way. Keeping a food diary can be a helpful way to identify personal triggers and develop a plan to avoid them. Working with a healthcare professional or registered dietitian can also provide personalized guidance on managing mast cell activation through dietary changes.
How do I know if I have mast cell activation?
If you’re experiencing symptoms such as hives, itching, flushing, or digestive issues after eating certain foods, you may be experiencing mast cell activation.
