What Are lectins?

Lectins are types of protein that, in humans, may help cells interact with one another. Some scientists also believe that lectins provide a form of defense in plants to keep insects away. These proteins also contain nitrogen, which is needed for plants to grow.

  • OUR #1 LECTIN SHIELD SUPPLEMENT is an advanced physician created formula to bind harmful lectins in diet to support optimal nutrient absorption and health.
  • OUR SUPPLEMENTS ARE MANUFACTURED IN A FACILITY FOR LICENSED HEALTH CARE PROVIDERS, to ensure the most effective ingredients, freshness, and extremely fast turnaround.
  • NATURAL DIETARY INGREDIENTS ARE USED TO BLOCK HARMFUL LECTINS in diet; Vegetarian Capsule; N-Acetyl Glucosamine (crab, shrimp), Bladderwrack whole plant, Okra Fruit, D-Mannose, Mucin, Sodium Alginate, and Pepsin. Pepsin is naturally produced in the stomach and it is one of the main digestive enzymes in the digestive system to digest proteins. Lectins are types of proteins.
  • PROTECT YOUR GUT LINING AND HEALTH with Anti Lectin Supplement, since Lectin-free diet may be difficult to follow, and legumes, nuts, seeds, and whole grains provide the main plant-based protein.
  • ANTI LECTIN SUPPLEMENT IS MANUFACTURED UNDER STRICT QUALITY MANAGEMENT SYSTEM in USA from premium carefully selected ingredients in FDA-inspected facility and with third party quality certifications. 

Sow The Seeds

While many parts of plants contain lectins, the seed is the part that people eat most often. Lectins may impact health in multiple ways, ranging from digestion to chronic disease risk. They have been shown to cause red blood cells to cluster together.

Red Offender

The lectin in red kidney beans is called phytohaemagglutinin. It is responsible for red kidney bean poisoning, which results from eating raw or undercooked kidney beans. According to the United States Food and Drug Administration (FDA), consuming just four raw kidney beans could cause symptoms including severe nausea, vomiting, and diarrhea.

Castor Oil Is Still Safe

Lectins were first described in 1888 by Stillmark, who observed that crude extracts of castor beans (Ricinus communis) contained a toxic substance named ricin that agglutinated human and some animal red blood cells. However, the modern age of lectinology started nearly 100 years later (Bies et al., 2004; Sharon and Lis, 2004). Only few drops of ricin can kill an adult.

Legume Lectin Content

Lectins are found in abundance in legume seeds. Phaseolus vulgaris is an herbaceous annual plant grown worldwide for its edible beans, popular in both dry and green bean forms. The commercial production of beans is well distributed worldwide.

Immune System And Lectins

Because we don’t digest lectins, we often produce antibodies to them. Almost everyone has antibodies to some dietary lectins in their body. This means our responses vary. Certain foods can even become intolerable to someone after an immune system change or the gut is injured from another source. The presence of particular lectins can stimulate an immune system response.

Bath Is Not Enough For The Red Offender

There are some lectins that no one should consume. Ever wonder why you don’t see sprouted red kidney beans? It’s due to phytohaemagglutinin – a lectin that can cause red kidney bean poisoning. The poisoning is usually caused by the ingestion of raw, soaked kidney beans. As few as four or five raw beans can trigger symptoms.

Raw kidney beans contain from 20,000 to 70,000 lectin units, while fully cooked beans usually contain between 200 and 400 units.

What you should know about lectins

Ingesting lectins can cause flatulence. Consuming legumes and grains in their raw form can even result in nausea, diarrhea and vomiting. Indeed, researchers speculate that many apparent causes of bacterial food poisoning may actually be lectin poisoning.

Lectins and the intestinal wall

This GI distress happens because lectins can damage the intestinal lining.

As food passes through the gut, it causes very minor damage to the lining of the GI tract. Normally the cells repair this damage rapidly. Since the purpose of the gut lining is to let the good stuff past and keep the bad stuff contained, it’s important for the cellular repair system to be running at full efficiency.

Lectins And Leaky Gut

But lectins can blunt this speedy reconstruction. Our cells can’t regenerate as fast as they need to in order to keep the intestinal lining secure. Thus, our natural gut defenses are compromised after the damage occurs and the gut can become a “leaky gut,” allowing various molecules (including stuff we don’t want) to pass back and forth amid the gut wall. We may also not absorb other important things, such as vitamins and minerals, properly.

..and Then We Run

When enough lectins are consumed, it can signal our body to evacuate GI contents. This means vomiting, cramping and diarrhea. It’s similar to consuming large amounts of alcohol, which can damage the GI lining and cause GI evacuation.

Lectins and immune response

When lectins affect the gut wall, it may also cause a broader immune system response as the body’s defenses move in to attack the invaders.

Symptoms can include skin rashes, joint pain, and general inflammation. Other chronic disorders may be correlated with leaky gut — for example; researchers have even noted that children with autism have very high rates of leaky gut and similar inflammatory GI tract diseases.

When someone suffers from Crohn’s disease or irritable bowel syndrome (IBS), the gut lining seems to be more sensitive to food lectins. This might be due to the high turnover of cells and greater population of the immature variety. These immature cells have plenty of spots for lectins to attach.


Unrefined grains are more nutritious than refined versions because they contain more nutrients. However, they also provide more lectins (and other anti-nutrients).

While this was likely never a problem when we grew and harvested our own grains, we now have access to MANY whole grain products. Before the invention of modern agriculture, grains were a minor and seasonal crop. Now we can go to the market for 15 minutes and have a cart full of whole grain pasta, bread, rice, quinoa, kamut, amaranth, oats, barley and chips.

The average North American diet is highly grain-based: bread, pasta, rice, cereals, etc. are everywhere, especially in processed foods.

Was the body ever equipped to deal with that type of grain onslaught?

Our ancestors grasped the concept of “survival of the fittest,” and found a solution to the problem of lectins. Soaking, fermenting, sprouting and cooking will decrease lectins and free up the good nutrients. The content of lectins in foods differs year to year and crop to crop.

Grain, cereal, dairy, and legume (especially peanut and soybean) lectins are most commonly associated with reports of digestive complaints. Legumes and seafood are the most abundant sources of lectins in most diets.

What is An Anti-Nutrient

Lectins are categorized as antinutrients since they block the absorption of some nutrients. Lectins may cause an upset stomach when plant foods are eaten uncooked. They are also the reason why it can be dangerous to eat undercooked legumes. 


Some scientists believe lectins are harmful and cause inflammation. An older research links them to autoimmune diseases, including celiac disease, diabetes, and rheumatoid arthritis.

Lectins And Inflammation

One journal discusses the research associated with wheat germ lectin. It may impact the immune system by increasing inflammation.

Long-term inflammation is linked to many serious medical conditions, including heart disease, cancer, and depression.

Following a lectin-free diet could be a way to lower inflammation in the body. However, more research in humans is needed before the effect can be confirmed.

The researchers also report that lectins may make it easier for bacteria or other toxins to cross the gut barrier. However, they also state that whole grains contain antioxidants, which help fight inflammation. This factor could make up for lectin's potentially harmful effects.

Lectin Free Diet

The lectin-free diet is a restrictive plan, which may make it difficult for some people to follow it long-term. The plan also limits or cuts out many nutritious foods, such as whole grains, beans, and certain vegetables.

A lectin-free diet may be difficult for vegetarians or vegans to follow, since legumes, nuts, seeds, and whole grains provide plant-based protein. Legumes, whole grains, and fruit and vegetable peels also provide dietary fiber. A lectin-free diet could result in constipation if dietary fiber intake decreases.


According to research, the following foods are recommended for people trying to limit their lectin intake:

  • Pasture-raised meats
  • A2 milk
  • Cooked sweet potatoes
  • Leafy, green vegetables
  • Cruciferous vegetables, such as broccoli and Brussels sprouts
  • Asparagus
  • Garlic and onion
  • Celery
  • Mushrooms
  • Avocado
  • Olives or extra virgin olive oil


According to Research, people should limit the following foods when trying to avoid lectins:

  • Legumes, such as beans, peas, lentils, and peanuts squash.
  • Nightshade vegetables, such as eggplant, peppers, potatoes, and tomatoes fruit, although in-season fruit is allowed in moderation.
  • Grains

If grains are consumed, the plan recommends products made from white flour instead of wheat.

Also, we recommend completely avoiding the following foods:

  • Corn
  • Meat from corn-fed animals
  • A1 milk



Lectins are carbohydrates that are bound to proteins. Plants make them to protect themselves from insects and diseases. They are found in high, potentially “toxic”, concentrations in wheat, rye, barley, wheat germ, quinoa, rice, oats, millet and corn. 

Also legumes, all dried beans, soy and peanuts. Dairy, especially from grain-fed cows as opposed to grass-fed cows. Nightshades like potato, tomato, eggplant and pepper contain them as well.

Lectins have been documented to cause “food poisoning” in people without any bacteria or pathogen being found. Lectins are toxic, inflammatory, or both. They are resistant to cooking and digestive enzymes so they aren’t easily broken down.

Lectins in wheat, kidney beans, soybeans and peanuts are known to increase intestinal permeability (a leaky gut). This allows proteins, bacteria, amino acids, undigested food, and viruses to crossover into the body. 

Usually the immune system is quick to attack and eliminate these foreign invaders. However, Lectins also impair the immune systems ability to fight off these fragments that leak into the body. 

Some intestinal bacteria, immune system proteins, food proteins, and body tissues, have the same protein sequences, further confusing the immune system. This causes the immune system to attack itself and the body’s tissues as if they are invaders! 

Enter, autoimmune diseases!

Also, wheat contains gluten, which compounds the Lectin problem!

Gluten Sensitivity

Current estimates of gluten sensitivity in the US are 30-40% of the population with the majority of these people not even being aware that they have the problem. 

People who are the most sensitive end up with Celiac’s Disease. Gluten causes inflammation in the gut lining and pain. 

Celiac’s Disease can cause severe symptoms (Ciliac’s) or be subclinical and exhibit almost no symptoms. With time though, people will begin to exhibit clinical symptoms: abdominal cramping, dry skin, dry hair, diarrhea, nausea, constipation, and low energy to name just a few.

So, how do Lectins cause me to gain weight and not be able to lose it? 

Lectins interfere with leptin. Leptin tells us to stop eating, stores excess calories in fat, supports the growth of blood vessels, bone, the immune system, glucose- and fat-metabolism, and the reproductive system. 

In mice, the administration of leptin causes satiation and weight loss. In overweight humans it does not. Overweight humans often have high levels of leptin already. This points to Leptin Resistance as a cause of their obesity. 

Lectins appear to interfere with leptin receptors, blocking leptin’s effect of controlling appetite/satiation. This may lead to an increase in glucose in the blood and start insulin resistance (Type II Diabetes) in some people. 

Lectins may also contribute strongly to the metabolic syndrome.

So, where do you think you would be if you followed the old USDA food pyramid? 

It recommended 6-11 servings of grain a day!

Consider how much the obesity rate in the US has gone up and you might just see a connection.

How do you reverse the process? 

The first step is to get off of the foods that have potentially toxic Lectins in them. Hunter-Gatherer diets, the Paleo diet, the Atkins diet, and other similar diets will reduce your exposure to Lectins. However, you should consult with your physician/nutritionist before starting any dietary program to make sure that it is right for you and your problems.

The majority of people do not even know what a leaky gut is. Most people are surprised to learn that 70% to 80% of your immune system is in your gut! The reason for the concentration of your defensive system in this area is the bacteria that are growing there. 

There are more bacteria in your gut then there are cells in your body! These bacteria help us digest and break down our food so that it can be absorbed. We supply them with things that they need and we can’t use. These include fiber and sugars that we are unable to digest or utilize. The bacteria eat these. This forms a symbiotic relationship that works quite well, when it goes as it was designed too. When the system develops a problem, we pay a price.

Causes of Leaky Gut

What can cause the system to go out of balance? Medications (antibiotics), diet, stress, bad bacteria, yeasts, fungi, and food allergies. Antibiotics set the stage for problems because they destroy most of the bacteria in the gut. Good, bad, or indifferent, they all go. This leaves the gut open to invasion by yeasts, fungi, and molds. 

If you use antibiotics, you must repopulate your gut with good bacteria as soon as possible to prevent over-growth of bad organisms. Probiotics should contain several different organisms to provide adequate coverage.

Diet, including food allergies, is one of the most common ways to develop a leaky gut. Gluten, found in wheat, barley, rye, spelt, malt, and oats, contains compounds called lectins. Lectins are sugars attached to proteins or fats. These compounds cause irritation and inflammation of the gut.

This inflammation and irritation causes the junctions between the cells in the gut to loosen. When the gaps between the cells lining the gut widen, all kinds of things can cross into the body, partially digested proteins, bacteria, and other products slip through. 

The immune system assumes that proteins made up of three or four amino acids is a virus and mounts an attack on it. If one of the bodies organs or other parts happens to have the same combination of amino acids, the immune system will attack it too. 

Enter autoimmune conditions like rheumatoid arthritis, lupus, and Hashimoto’s autoimmune thyroiditis.

So what can you do to fix this problem? The first step is to identify the source of the leaky gut. I have only discussed a few of the more common ones. It often takes testing and a through history in order to discover the source or sources of your specific problem. 

The second step is to eliminate it from your life. Next, you may need to detoxify in order to eliminate the products of the leaky gut from your system. Lastly, you will need to heal you gut through nutritional means in order to seal up the leaks and enable you to improve your overall health.

The gut is a crucial and often overlooked part of your total health. People may have gut problems without symptoms. Other people end up with Irritable Bowel Disease (IBD), Celiac’s Disease, and Gastritis, to name a few. 

Until this area is assessed and properly treated, no program, nutritional or otherwise, will cause lasting improvements in your health!


When Lectins are in small amounts, they may provide several health benefits. However, large amounts can damage the gut wall. This causes irritation that can result in symptoms such as diarrhea and vomiting. It can also prevent the gut from absorbing nutrients properly.

The highest concentrations of lectins are found in healthy foods like legumes, grains and nightshade vegetables. 

Luckily, there are several ways to reduce the lectin content of these healthy foods to make them safe to eat.

Research shows that by cooking, sprouting or fermenting foods that are high in lectins, you can easily reduce their lectin content to negligible amounts.

This chapter reviews six foods that are particularly high in lectins, and explains how you can make sure they don't reduce your nutrient absorption.

Below are six healthy foods that are high in lectins.


Red kidney beans are among the richest sources of plant-based protein. They are also a great source of carbs that are low on the glycemic index (GI). This means that they release their sugars more slowly into the blood, causing a gradual rise in blood sugar rather than a sharp spike.

They are also high in resistant starch and insoluble fiber, which can help with weight loss and improve general gut health. Red kidney beans contain many vital vitamins and minerals, such as iron, potassium, folate and vitamin K1. However, raw kidney beans also contain high levels of a lectin called phytohaemagglutinin.

If you eat them raw or undercooked, they can cause extreme nausea, vomiting and diarrhea. As few as five beans can cause a response. A hemagglutinating unit (hau) is a measure of lectin content. In their raw form, red kidney beans contain 20,000–70,000 hau. 

Once they're thoroughly cooked, they contain only 200–400 hau, which is considered a safe level. As long as they are properly cooked, red kidney beans are a valuable and nutritious food that shouldn't be avoided.


Soybeans are a fantastic source of protein. They are one of the highest quality plant-based proteins, which makes them particularly important for vegetarians. They are a good source of vitamins and minerals, particularly molybdenum, phosphorus and thiamine.

They also contain plant compounds called isoflavones, which have been linked to cancer prevention and a decreased risk of osteoporosis. Research shows soybeans can also help lower cholesterol and reduce the risk of developing obesity and type 2 diabetes.

However, soybeans are another food that contains high levels of lectins. As with red kidney beans, cooking soybeans almost completely eliminates the lectins. Yet make sure you cook them for long enough at a high enough temperature.

Research shows that soybean lectins are almost completely deactivated when they're boiled at 212°F (100°C) for at least 10 minutes. In contrast, dry or moist heating of soybeans at 158°F (70°C) for several hours had little or no effect on their lectin content.

On the other hand, fermentation and sprouting are both proven methods of reducing lectins. One study found that fermenting soybeans reduced the lectin content by 95%. Another study found that sprouting decreased the lectin content by 59%. 

Fermented soybean products include soy sauce, miso and tempeh. Soybean sprouts are also widely available, and can be added to salads or used in stir-fries.


Wheat is the staple food for 35% of the world's population. Refined wheat products have a high glycemic index (GI), which can cause your blood sugar to spike. They've also been stripped of virtually all nutrients. Whole wheat has a similar GI, but it's higher in fiber, which can have beneficial effects on gut health.

Some people have difficulty digesting gluten, a protein found in wheat. However, if you tolerate it, then whole wheat can be a good source of many vitamins and minerals, such as selenium, copper and folate. Whole wheat also contains antioxidants such as ferulic acid, which has been linked to a reduction in heart disease. 

Raw wheat, especially wheat germ, is high in lectins, with around 300 mcg of wheat lectins per gram. However, it appears that the lectins are almost completely eliminated by cooking and processing.

Whole-wheat flour has a much lower lectin content of about 30 mcg per gram. When you cook whole-wheat pasta, it appears to completely inactivate the lectins, even at temperatures as low as 149°F (65°C). In cooked pasta, lectins are undetectable. 

Moreover, research shows that store-bought whole-wheat pasta doesn't contain any lectins at all, since it's usually exposed to heat treatments during production.


Peanuts are actually classified as legumes, and are related to beans and lentils. They are high in mono- and polyunsaturated fats, making them a great source of energy. They are also high in protein and a wide range of vitamins and minerals, such as biotin, vitamin E and thiamine.

Peanuts are also rich in antioxidants, and have been linked to health benefits like a reduced risk of heart disease and gallstones. Unlike with some of the other foods on this list, the lectins in peanuts don't appear to be reduced by heating. A study found that after participants ate 7 ounces (200 grams) of either raw or roasted peanuts, lectins were found in their blood, indicating that they had crossed through from the gut.

One test-tube study found that peanut lectins increased growth in cancer cells. This, alongside the evidence that peanut lectins can enter the blood stream, has led some people to believe that lectins could encourage cancer to spread in the body.

However, this study was carried out using high doses of pure lectins placed directly onto cancer cells. There are no studies as yet on the exact effects in humans. So far, the evidence for peanuts' health benefits and role in cancer prevention is far stronger than the evidence for any potential harm they might cause.


Tomatoes are part of the nightshade family, along with potatoes, eggplants and bell peppers. Tomatoes are high in fiber and rich in vitamin C, with one tomato providing approximately 28% of the recommended daily intake. They are also a good source of potassium, folate and vitamin K1.

One of the most studied compounds in tomatoes is the antioxidant lycopene. It has been found to reduce inflammation and heart disease, and studies have shown it may protect against cancer. Tomatoes also contain lectins. 

The available studies have been on animals or in test tubes. In one study on rats, tomato lectins were found to bind to the gut wall, but they didn't appear to cause any damage.

Another study found that tomato lectins do manage to cross the gut and enter the bloodstream once they've been eaten. Indeed, some people do appear to react to tomatoes, but this is more likely to be due to something called pollen food allergy syndrome or oral allergy syndrome. 

Some people have linked tomatoes and other nightshade vegetables to inflammation, such as that found in arthritis. So far, no formal research has supported this link. Lectins have been linked to rheumatoid arthritis, but only for those who carry genes that put them at a high risk of the disease.


Potatoes are another member of the nightshade family. They are a very popular food and are eaten in many forms. Eaten with the skin, potatoes are also a good source of some vitamins and minerals.

They contain high levels of potassium, which has been shown to decrease the risk of heart disease. They are also a rich source of vitamin C and folate. The skins, in particular, are high in antioxidants, such as chlorogenic acid. This compound has been associated with a reduction in the risk of heart disease, type 2 diabetes and Alzheimer's disease.

Potatoes have also been shown to increase feelings of fullness, which can help with weight loss. That said, it is important to consider how they are cooked. Potatoes are high in lectins that appear to be resistant to heat. About 40–50% of their lectin content remains after cooking.

As with tomatoes, some people report experiencing adverse effects when they eat potatoes. Animal and test-tube studies have shown that this could possibly be linked to lectins. However, more studies in humans are needed.

Since lectins are so widely distributed in food items commonly consumed by humans, and have been for many centuries, most nutrition experts assume they don’t pose a significant risk to human health.

Still, it does appear that chronic ingestion of untreated high-lectin foods may warrant further consideration. If you consume a diet with plenty of lectin-rich foods, try to reduce the amount by soaking, fermenting, sprouting and/or cooking.

And then again, you can reduce impact of Lectins to your health with a specific supplement, like our Anti Lectin Supplement.
