Have you ever heard of lectin-free diet regimen? Are they good or bad for your health? Do you need to eliminate them from your meal? But what are lectins, by the way? Take this two-minute read to learn more about lectins, health benefits, and the merits and demerits of this diet regimen.
What Are Lectins?
Lectins are proteincompounds that bind to other carbohydrates and are termed “anti-nutrients” because they are not easily digestible in the intestine and can prevent the body from absorbing vital minerals like calcium, phosphorus, iron and zinc.
These compounds also attach to the cells lining the intestines and can stay there longer. As a study published in the Journal of Immunology Research found, lectins have the potential to cause an autoimmune response.

What Is A Lectin-Free Diet?
A lectin-free diet is a dietary plan that involves avoiding foods high in lectins. Lectins are a protein found in many plants that can bind to carbohydrates. They are considered anti-nutrientsbecause they can impede nutrient absorption and cause digestive problems in some people. The diet gained popularity mainly due to Dr. Steven Gundry's book, "The Plant Paradox," which suggests that reducing lectin intake can improve health and alleviate various health issues.
How Does The Lectin-Free Diet Work?
The lectin-free diet eliminates or reduces the intake of foods high in lectins. The idea is to prevent potential negative effects on digestionand overall health caused by lectins. This diet focuses on consuming lectin-free or low-lectin foods and preparing foods in ways that reduce their lectin content, such as soaking, fermenting, and pressure cooking.
Possible Health Impacts
Digestive Reactions
Consuming lectin-rich foods may lead to digestive distress in some people. This is because the system cannot digest lectins, but they bind to cell membranes lining the intestinal tract, where it may impede the metabolism and cause damage.
Those suffering from underlying digestive conditions like irritable bowel syndrome (IBS), may observe negative effects after eating antinutrients like lectins.
Avoiding foods that trigger digestive issues and seeking immediate medical help to ease symptoms is better.
Toxicity
Several types of lectins have various effects on the system. A few are highly toxic, including ricin, a toxin obtained from castor beans, while others are harmless. So, it’s vital to refrain from having raw, soaked, or undercooked beans, as they can be harmful and toxic.
Phytohemagglutinin, a lectin found high in kidney beans, can result in nausea, severe vomiting, and diarrhoea just after having 4 or 5 raw beans.
The best possible way to remove lectin is to soak beans for 30 minutes before cooking, which makes the beans safe to consume.
Why Should I Try A Lectin-Free Diet?
Most foods that contain lectin are considered safe and well-tolerated by most people as long as they are well-cooked.
People with digestive sensitivities may experience negative impacts after having these foods. Hence it is best to avoid any foods that cause digestive issues.
