According to an old definition “lectins are carbohydrate-binding proteins or glycoproteins.” William Boyd coined the term “Lectin” in 1954 from the latin word legere meaning “to choose.” Boyd was also the first researcher to identify the blood type specificity of many common dietary lectins. Typically lectins can bind to many of the carbohydrate antigens found in the gut and immune system, causing a variety of health problems. “These can include intestinal dysbiosis, bowel hyperpermiability, immune dysfunction, food sensitivities and systemic inflammation. This is usually accomplished by direct agglutination of the target cells. Lectins can occur in very common foods in the diet, and the majority are specific for the carbohydrates of the ABO blood typing system. In one study, the edible parts of 29 of 88 foods tested, including common salad ingredients, fresh fruits, roasted nuts, and processed cereals were found to possess, significant lectin-like activity as assessed by hemagglutination and bacterial agglutination assays.
