Here, a list of high-lectin foods and how to prepare them: Red Kidney Beans. Red kidney beans are an excellent plant-based source of protein and fiber, however, it is essential to soak and cook ...
Lectins are similar to antibodies in their ability to agglutinate red blood cells. [33] Many legume seeds have been proven to contain high lectin activity, termed hemagglutination. [34] Soybean is the most important grain legume crop in this category. Its seeds contain high activity of soybean lectins (soybean agglutinin or SBA).
The lectin-free diet forbids all foods that are high in lectins including legumes (beans, chickpeas, lentils, peas), grains, fruit, nightshade vegetables (tomatoes and potatoes), nuts, seeds and many others. [2] [5] The first writer to advocate a lectin-free diet was Peter J. D'Adamo, a naturopathic physician best known for promoting the blood ...
Phytohaemagglutinin (PHA, or phytohemagglutinin) is a lectin found in plants, especially certain legumes. PHA actually consists of two closely related proteins, called leucoagglutinin (PHA-L) and PHA-E. These proteins cause blood cells to clump together. PHA-E cause erythrocytes (red blood cells) to clump.
The legume lectins are also interesting from the point of view of protein structure. Despite the conserved structure of the legume lectin subunit, they can adopt a wide range of quaternary structures. [4] [5] The reason behind this remarkable variability is probably to be found in the interaction with multivalent ligands. [6]
Concanavalin A (ConA) is a lectin (carbohydrate-binding protein) originally extracted from the jack-bean (Canavalia ensiformis).It is a member of the legume lectin family. It binds specifically to certain structures found in various sugars, glycoproteins, and glycolipids, mainly internal and nonreducing terminal α-D-mannosyl and α-D-glucosyl groups.
Soybean agglutinins (SBA) also known as soy bean lectins (SBL) are lectins found in soybeans. It is a family of similar legume lectins. As a lectin, it is an antinutrient that chelates minerals. In human foodstuffs, less than half of this lectin is deactivated even with extensive cooking (boiling for 20 minutes). [1]
Wheat germ agglutinin (WGA) is a lectin that protects wheat from insects, yeast and bacteria. An agglutinin protein, it binds to N-acetyl-D-glucosamine and sialic acid . [ 1 ] WGA has also been shown to interact with sialic acid residues on oligosaccharides. [ 2 ]
