Lentil Allergy Symptoms and Treatment

Lentils are legumes that are very nutritious and contain high dietary fiber. Lentil allergy is an adverse reaction caused by the body’s immune system to lentils and foods containing lentils. Histamine and Immunoglobulin E (IgE), an antibody, is produced by the immune system of the body when the body comes in contact with lentils. The symptoms caused due to lentil allergy can vary considerably.

Lentils are packed with vitamins and contain rich protein. These are considered legumes and belong to the family of peanuts and beans. So, if a person is allergic to one type of lentil, he might also be allergic to another. If a person is allergic to lentils, one must check out the symptoms and choose to eat other plant-based proteins.

What is Lentil Allergy – Symptoms and Treatment

This allergy is caused due to high protein content present in the legumes. According to the USDA, one cup of cooked lentils contains about 18 g protein, 15 g fiber, 3.5 g sugar, 40 g carbohydrates, less than 1 g fat, and 230 calories. The article discusses the primary symptoms caused due to lentil allergy and its treatment in the following lines.

Symptoms of Lentil Allergy

Allergies to lentils or legumes manifest the same symptoms for all types of legumes. They might range from oral allergy, rhinitis, urticaria, angioedema, and asthmatic crisis to anaphylactic shock etc.

Some of the common symptoms caused by lentil allergy are as follows:

• Diarrhea, nausea and vomiting
• Swelling on lips, mouth, and tongue
• Skin reactions like rashes, hives, intense itching, and redness
• Common cold or hay fever-like symptoms can lead to watery eyes and clogged nasal passage with a runny nose and wheezing
• Anaphylaxis: Severe symptoms can be caused by dizziness, breathlessness, and a sudden decrease in blood pressure

The most commonly seen symptoms of lentil allergy include skin reactions and respiratory symptoms. The above-mentioned signs of the condition can be diagnosed by carrying out skin tests and blood tests like RAST. They reveal the allergen causing this state and the severity.

Treatment of Lentil Allergy

Lentil soup should be avoided, and it should also be avoided in any other form to prevent a recurrence. It is said that cooking the lentil can weaken the allergen, but the problem can still persist. Even the steam from the lentil cooking pot can cause severe allergic reactions in some persons. Some of the effective ways to treat lentil allergy are:

• Some mild to moderate symptoms of lentil allergy can be effectively controlled by applying medicated skin creams (corticosteroids) and antihistamines
• Severe and anaphylactic symptoms such as dizziness and breathlessness require emergency intervention and epinephrine injections. These can also be self-administered through Epi-pen
• An allergic person can still get plant protein, avoiding legumes due to lentil allergy. A need to introduce beans, edamame, sprouts, soy nuts, alfalfa, and certain nuts into the diet to meet the daily requirement of protein. Nuts like walnuts, cashews, and almonds are a great source of fat and protein

One must be very careful while eating outside and shopping for food. Ensure the restaurant food does not contain lentils and read the food product’s label carefully before buying.

Depending upon the state of the patient’s immune system, the severity of the signs becomes apparent. Mild signs may not require any treatment as they come and go. Moderate severity signs may also require antihistamine drugs, adrenaline injections, and bronchodilators for patients who suffer from asthma.

Severe cases though rare may involve what is technically called anaphylaxis. It is a medical emergency where the allergy spreads all over the body, quickly affecting the organs. Medical intervention is required as early as possible, and hospitalization of the patient under such a life-threatening condition is a must.

Cross Reactivity

Cross-reactivity is caused due to similar compounds present in some allergens, or allergies can also be caused due to closely related foods. Research shows that people who are allergic to some lentils also have allergies to chickpeas and peas. Though in the United States, peanut allergy is common, cross-reactivity with peanuts is not that common.

If you are unsure of lentil allergy, you should talk to your physician, who will refer you to an allergist for the test. He will then advise you better about what foods to eat or what to avoid for your better health.

Cross-Reactivity Between Lentils and Other Legumes

Note: Cross-reactivity levels are based on clinical observations and might vary among individuals. It’s essential to consult with an allergist for personalized advice.

Do lentils trigger histamine?

Some evidence suggests that lentils may trigger the release of histamine in some people. Histamine, a chemical produced by the body plays a role in the immune system and in regulating digestive and cardiovascular function. In people with allergies or intolerances, the body may produce too much histamine or be unable to break it down effectively, leading to symptoms such as itching, hives, and swelling.

Are lentils hard on the gut?

Lentils are a good source of fiber and nutrients and are generally well tolerated by most people. However, some people may experience digestive symptoms after consuming lentils, primarily if they are not used to eating a lot of fiber. Signs of digestive distress after consuming lentils might include bloating, gas, abdominal cramps, and diarrhea. These symptoms are usually temporary and can be relieved by drinking plenty of fluids and eating smaller, more frequent meals.

What are the side effects of lentils?

Lentils are a healthy and nutritious food that can be enjoyed as part of a well-balanced diet. However, suppose you have concerns about your ability to tolerate lentils or have a pre-existing health condition. In that case, you should talk to your healthcare provider before adding them to your diet.

Lentil Allergy FAQs

Can you be allergic to lentils?

Lentils can be a potential allergen, but the risk of an allergic reaction is low. Several factors can contribute to an allergy to lentils, including cross-reactivity with other legumes such as peanuts and soy, eating them at the wrong time (before or after meals), and ingesting large quantities (>2 cups per day). If you have an allergy to lentils, avoid them entirely or check with your doctor for specific advice on managing them.

What foods are related to lentils?

Lentils are a legume that is related to beans and peas. They are an excellent source of plant-based protein, fiber, folate, magnesium, iron, and vitamin B12. Lentils also contain moderate levels of sodium and potassium. Additionally, lentils are low in calories and include plenty of minerals like potassium and magnesium.

When it comes to taste, most people find lentils quite bland. But they can be easily seasoned with spices like cumin or turmeric if you want to add flavor to your meals. Some foods related to lentils include rice, quinoa bowls and salads, curries, Indian naan bread, and pita sandwiches.

Why do lentils upset my stomach?

Lentils are high in fiber, and many people sensitive to gluten may struggle to digest them. In addition, fiber can travel through the digestive system undigested and cause bloating, gas, diarrhea, and even constipation- all of which can lead to an upset stomach. If you’re prone to these problems, it’s best to avoid Lentils altogether or probiotics containing lentils as an ingredient.
