Lectins, Low Lectin Foods, and the Mast Cell Connection – for those with Mast Cell Activation Syndrome or Histamine Intolerance

Lectins, Low Lectin Foods, and the Mast Cell Connection – for those with Mast Cell Activation Syndrome or Histamine Intolerance

My knees, fingers, and toes were constantly swollen, and my joints always felt like they were on fire. 

The level of pain I experienced was so bad that I had been (mis)diagnosed with Rheumatoid Arthritis. 

I was also frequently bloated with lots of abdominal pain.  

And brain fog was interfering with my ability to do anything. Chores were left undone. Mail was left unopened. Even basic self-care like showering was a struggle.  

I was so exhausted all the time. 

Have you felt like this, too? 

I had already done a lot of work on my health. After I worked on my Histamine Intolerance and Oxalate issues, I was getting better.  

I no longer had soul-crushing pain and anxiety. I felt like I was making progress.  

But I was still experiencing so many symptoms.  

How could I have come this far to still feel so sick? 

I was always looking for answers to that question.

One day, I was talking with a colleague about my ongoing issues and Lectin Sensitivity came up.  

To be honest, for several months, I resisted exploring it further. I’d made so many changes to my diet already. 

But one day, the pain got so bad, I could hardly move.  

So, I went back and read everything I could on lectins. I was desperate. 

The night before, I’d eaten a corn tortilla with bell peppers, quinoa, zucchini, and potatoes for dinner. 

Little did I know, it was a lectin smorgasbord!  

I went on to read that for those with lectin sensitivities, lectins can trigger mast cells. And that can result in symptoms like burning joints.  

Fast forward: Within 2 weeks of coming off lectins, the burning pain in my knees, fingers, and toes was completely gone!  

I couldn’t believe it! I finally felt some relief! 

Lectin Sensitivity is particularly important to know about with Mast Cell Activation Syndrome.  

Many of us with mast cell issues, or any form of Autoimmunity, may have Lectin Sensitivity. Particularly, if we’ve had mold exposure. I’ll tell you more about that in a bit. 

Before we go any further, though, know this — not everyone has trouble with lectins. So, please don’t limit your foods unnecessarily.  

But lectins can trigger Mast Cells for many people. And many people who are sensitive to lectins have gotten really good results by shifting to a Low Lectin, Low Histamine diet. 

This goes back to lectins being a trigger of Autoimmunity and Mold Toxicity, according to several studies.  

So, if you’ve dealt with Mast Cell Activation Syndrome, Mold Toxicity, or Autoimmunity, keep reading to see if this is something that might help you.  

First, let’s cover the signs that lectin sensitivity could be a problem. Then, we’ll go over what lectins are and why they could potentially be a mast cell trigger for you. 

Signs and Symptoms of Lectin Sensitivity –What to know when you have Mast Cell Activation Syndrome or Histamine Intolerance

It’s important you know that this blog post is for informational and educational purposes. It’s not meant to treat any health condition or to be prescriptive for anyone. If you have any medical condition, it is critical you work under the care and guidance of a licensed medical provider. 

Are any of the following symptoms familiar to you?

  • Fatigue 
  • Lack of motivation 
  • Brain fog 
  • Pain in the joints and elsewhere in the body 
  • Skin breakouts 
  • Digestive problems including bloating, gas, nausea, and irritable bowel syndrome 

Well…all those symptoms can be related to Lectin Sensitivity.   

But keep in mind that reactions can come from any number of factors like: 

  • other types of foods (like high histamine foods or oxalates or FODMAPs) 
  • environmental triggers such as chemical toxins in skin or home care products 
  • nervous system dysregulation 
  • mold toxicity 

And more…  

But if your symptoms start within a few minutes to a few hours after eating meals loaded with lectin foods, Lectin Sensitivity could be a problem.  

Lectin sensitivity may also contribute to the following conditions: 

  • Mental health issues, such as anxiety, depression, and psychosis 
  • Neurodegenerative diseases 
  • Autoimmune diseases 
  • Inability to gain or lose weight 
  • Blood sugar problems 
  • Water retention 
  • Excessive mucus 

So, you might be asking yourself, “What exactly are lectins and how are they causing these issues?” 

Great questions. 

Let’s start with what lectins are. 

What Are Lectins? What to know when you have Mast Cell Activation Syndrome or Histamine Intolerance

It’s important you know that this blog post is for informational and educational purposes. It’s not meant to treat any health condition or to be prescriptive for anyone. If you have any medical condition, it is critical you work under the care and guidance of a licensed medical provider. 

There are many, many types of lectins. 

Lectins can be found in plants. (And technically animals make certain kinds of lectins too) 

Lectins are proteins that help cells correctly recognize each other.  

Lectins in your body play an important role in cell communication. One of the biggest roles is that lectins help immune cells recognize your own cells from outside invaders, like infections. 

So, the lectins your own body produces aren’t the problem here. But your own body can sometimes respond to the lectins in plants in a negative way. 

Many plant lectins are harmless, but some plant lectins can be triggers for mast cell activation because they mess up our own cell communication. 

And some lectins are outright dangerous.  

Eating uncooked white kidney bean lectins, for example, is very unsafe. These lectins can cause a type of food poisoning if eaten raw.  

And caster bean ricin is a type of lectin so toxic is has been weaponized! 

Other lectins are not outright dangerous, but they can be problematic in very sensitive people. Unfortunately, these lectins are in very common food staples.  

Common food groups that have potentially problematic lectins include: 

  • Certain grains 
  • Beans and lentils 
  • Certain nuts 
  • Certain seeds, including seed-based spices 
  • Plants in the cucumber family, including melons, squash, and cucumbers 
  • Nightshade plants, such as tomatoes, peppers, and potatoes 
  • Genetically modified foods (GMOs) – these are made with potentially concerning lectins 

Cooking or pressure cooking can break down some lectin groups, though.  

Lectins can be reduced in these foods by peeling, seeding (for vegetables with seeds), and pressure cooking: 

  • Winter squashes (ie. spaghetti, acorn, butternut, etc)
  • Summer squashes (yellow, zucchini)
  • Potatoes
  • Rice
  • Oats
  • Beans
  • Lentils
  • Buckwheat 

This is the pressure cooker I use: 

What makes these lectins so harmful for some very sensitive people?

Managing Histamine, Salicylate, and FODMAP Intolerance with Mast Cell Activation Syndrome and Histamine Intolerance

Lectins can break down the gut barrier. 

Some lectins are known to open the gut barrier. For example, gluten found in wheat, rye, and barley can open the gut barrier. This can cause leaky gut. 

By opening the gut barrier, lectins can expose the content inside the gut to the immune system. The content may include food, bacteria, and gut bacteria. This can cause more food sensitivities. 

Very sensitive people often have weak digestion to begin with. So, a breakdown of the gut barrier just creates more problems. 

Lectins can contribute to autoimmunity.  

Dr. Alessio Fasano, MD, described the three requirements for the development of autoimmune diseases, including: 

  1. Genetic predisposition 
  2. Leaky gut 
  3. An environmental trigger (like mold toxins) 

We just talked about how lectins can contribute to #2 on this list – leaky gut. We’ll talk about the mold connection further down. So, for people with genetic predisposition, lectins can be one factor contributing to autoimmunity. 

Lectins can also affect the gut bacteria and throw them off-balance. The imbalanced or unhealthy gut bacteria can also contribute to autoimmunity. 

Some plant lectins can interfere with communications between your cells. 

Our cells normally talk to each other with hormones and cytokines. In the brain, neurons talk to each other with neurotransmitters.   

Some studies have shown that lectins may interfere with the functions of hormones, cytokines, and neurotransmitters.   

For example, at low doses, wheat germ lectins seems to block insulin function. 

Lectins from foods have also been found in the brains of patients with psychiatric disorders. Some of these lectins bind to neurotransmitter receptors and affect brain functioning.  

Lectins can have some specific concerns for people with Mast Cell Activation Syndrome, though. Let’s explore this next. 

The Lectin - Mast Cell Connection - What to know for those with Mast Cell Activation Syndrome or Histamine Intolerance

High Histamine Mast Cell 360

Mast cells have hundreds of different types of receptors on the outside of them. These receptors are sensing for anything concerning coming into your body. 

There is a specific receptor called a Toll-like receptor on mast cells. It senses things like bacteria, viruses, molds, and even lectins. 

When triggers like lectins come into contact with the mast cell Toll-like receptors, they set off a lot of mast cell activation in sensitive people. 

When these Toll-like receptors are getting overactivated, they trigger the mast cells to release a lot of their inflammatory mediators. 

In very sensitive people, problematic lectins can also cause leaky gut. This allows lectins to get absorbed into the bloodstream intact. 

In the bloodstream, they can activate all types of immune cells, especially mast cells. They can cause mast cells to release histamines and other mediators.  

Immunoglobulin E (IgE) also has a role in lectin sensitivities.  

IgE is a type of antibody that recognizes allergens. In people with allergies, IgE binding to allergens can activate mast cells. Lectins recognize a portion of IgE. Therefore, if you have some allergies or pre-existing Mast Cell Activation, food lectins can make these worse.  

A 2007 study in Clinical and Experimental Immunology found that potato lectins can activate both mast cells and basophils in people with allergic tendencies. The study concluded that people with allergies should not eat a lot of potatoes.  

Lectins can contribute to inflammation, especially for those with any of these: 

  • Mast Cell Activation Syndrome 
  • Histamine Intolerance 
  • Mold Toxicity 
  • Autoimmunity  

We talked earlier about factors that can make you sensitive to lectins. Here’s that list again. 

  • Genetic predisposition 
  • Immune system triggers, which may include mold toxicity and infections 
  • Stress or limbic system activation 
  • Deficiencies of nutrients that are important for immune tolerance, such as vitamins A and D, and Zinc 

One of those factors is immune system triggers…like mold toxicity. I see mold toxicity in over 90% of the clients in my Mast Cell 360 practice. And I’ve seen this be the root of a lot of sensitivities…including Lectin Sensitivity. 

What Is The Lectin – Mold Toxicity Link? Info for those with Mast Cell Activation Syndrome or Histamine Intolerance

We talked before about how lectins can trigger the Toll-like receptors on the mast cells.  

In people with Mold Toxicity, these Toll-like receptors are already getting hit hard by the mold in the body. And, over time, those receptors can become more sensitive to lectins because of mold. 

So basically, Mold Toxicity can lead to increases in lectin sensitivities. 

Mold Toxicity can worse lectin intolerance in other ways, too. 

Mold Toxicity can contribute to: 

  • A leaky gut 
  • Overall immune activation, including mast cells 
  • Nervous system problems 

See, lectins can also worsen leaky gut and activate the immune cells. Many people with Mold Toxicity also have a leaky brain. And, lectins can also worsen neurological and mental health issues.   

So lectins can become a big double-whammy in Mold Toxicity.  

I had severe Mast Cell Activation Syndrome and Mold Toxicity. 

Once I removed lectins, my joint pain and brain fog significantly improved. And I’ve seen it help many of our clients as well. 

Now, let’s look at whether you should consider eliminating lectins.  

How Can I Find Out If I’m Lectin Sensitive? What to know when you have Mast Cell Activation Syndrome or Histamine Intolerance

Before you change your diet on your own, please make sure you’re working with a healthcare practitioner who can help you with this. Never limit foods unnecessarily, and always have a licensed medical provider who is supervising your case.  

First, I want you to know not everyone can or needs to remove lectins. And if you are only able to eat a few foods, it’s not a good idea to restrict your foods even more. 

For example, some of our readers can only tolerate 10 foods or less. In these cases, it is usually not a good idea to remove more foods.   

But for those who can tolerate a variety of foods and suspect they may have reactions to lectins, it may be a good idea to experiment with removing lectins.   

Remember: 
Every case of lectin sensitivity is different. 
  

Two people can have very different reactions to the exact same food. For example, one person may have brain fog, while another has joint pain.  

You may also tolerate some lectins but not others. Or you may be able to tolerate some lectins in small doses. 

For example, I can eat melons just fine. And I do great with rice and can sometimes eat a little potato. But I really struggle with tomatoes and cucumbers. 

Others are just the opposite.  

If you do reduce your lectins, I am a big fan of keeping variety in your diet. Diet variety is linked to better health and longevity.  

Also, too restrictive diets can lead to or worsen: 

  • Nutrient deficiencies 
  • Social isolation, which is not healthy 
  • Unhealthy gut microbiome 

And you want to avoid those things if you are trying to heal. So, if you’re having any of those issues, be sure to work with a licensed medical provider. 

But if you do have lectin sensitivity and Mast Cell Activation Syndrome, lectins could be triggering your mast cells causing unwanted reactions. 

If you have some of the signs we talked about earlier and you are in a healthy place to experiment with your foods, you might want to explore lectin sensitivity further.  

If you suspect you may have Lectin Sensitivity, you might consider a low-lectin trial. 

What is A Low-Lectin Trial? Info for those with Mast Cell Activation Syndrome or Histamine Intolerance

An elimination trial is the gold standard for identifying food sensitivities.  

During a low-lectin trial, people will often try a low-lectin and low-histamine diet for 6 weeks. If they start to feel better, they will often re-introduce foods.  

I recommend keeping track of your symptoms in a food journal as you reintroduce foods. 

I also recommend re-introducing only 1 variable at a time. If you haven’t previously eliminated high histamine foods, your variables here are high histamine foods and high lectin foods.  

It can be helpful to remove the high histamine foods variable by sticking to low histamine foods during the re-introduction.   

For example, you may try reintroducing a serving of a lower histamine, higher lectin food on day 1.   

If you have no reaction to the food, then increase it to 2 servings on day 2.  

If you still have no reaction to 2 servings, then eat freely of the lectin-containing food on day 3.   

After these 3 days, if you experience no increase in symptoms, then you may be okay with that specific lectin-containing food. 

However, if you experience any reactions to the food or worse symptoms, I recommend that you stop eating the food. Then, go back to low-lectin and low-histamine foods until the reactions subside before re-introducing the next item.  

I’ve put together a guide below you can use to help you know which common foods are high lectin, low histamine and which are low lectin, low histamine. 

As always, be sure to work with a healthcare professional when making significant dietary changes. You want to be fully supported in your health journey!

I hope learning about lectins today has supported you, too!

    Hi Beth,
    Does sprouting beans, seeds, and legumes significantly reduce lectin content?

      Hi Lin,
      At this time, Beth hasn’t seen any research saying it does, so she doesn’t know the definitive answer for this. If you find some research which backs this, please let us know! We are always looking to learn!
