Lectin Sensitivity: What Are Lectins?

lectin-free diet | Gundry MDWhat are lectins in food? Lectins are dangerous plant proteins. And you will come across lectins when trying to consume a number of vegetables or legumes. Actually, lectins have turned out to be one of the natural world’s best weapons against any predator (animal or human).1

Lectins are “carbohydrate-binding proteins of nonimmune origin that agglutinate” various cells in your body.2 While that may seem like some scientific gibberish, it simply means that lectins are a kind of protein that force carbs to stick together. Lectins can also attach to various different cells in your body when you consume them.

Why Should You Avoid Foods Containing Lectins In Your Diet?

Imagine you consume some lectin-rich seeds. Or maybe you indulge in a whole wheat bagel or you chow down on the rind of your favorite lectin-heavy fruits or vegetables… the lectins in that plant food go on a spree to find the sugars in your body. And when they locate the ones they can stick to most easily, they latch on for dear life.

Sialic acid is just one kind of sugar in your gut, brain, nervous tissue, and human milk.3,4 But lectins can latch onto sialic acid (and other sugars). This ability has earned lectins the nickname “sticky proteins”.

Potential reactions could include diarrhea, nausea, or vomiting.6
