When we eat some lectins containing food, they start looking for the sugar in our body and bind/stick to them. The lectins are fond of sugar present in our gut, our brain, and the tissues of the nervous system. By way of sticking to these parts of the body, they come in the way of the normal functioning of these body parts. The lectins impact the communication amongst cells in the body. It can cause inflammation or digestive issues viz diarrhea, nausea, and digestion-induced symptoms. It can promote the sticking of bacteria and viruses to the cell in our body. The persons who have leaky gut and lectin intolerance are affected by its menace.
