According to The Institute for Natural Healing –
While most of the world seems to be touting the benefits of whole grains these days, a few people are insisting that grains are not as healthy as we think.
One of the reasons grains may be a problem in human nutrition is because they contain lectins, a class of molecules called glycoproteins (molecules that contain a protein and a sugar).
While dietary lectins are known in the scientific and nutritional communities, most lay people and even many medical professionals don’t know about them.
Lectins are involved in food allergies/sensitivities, inflammation and autoimmune disease, just to name a few. For instance, lectins are linked to celiac disease. Even weight gain and low energy can be linked to lectins.
Whole grains, peanuts, kidney beans, and soybeans are high in lectins. Cow’s milk, nightshade vegetables (like potatoes and tomatoes) and some seafood also contain fairly high amounts of lectin. In fact, estimates are that about 30% of our foods contain lectins, and about 5% of the lectins we eat will enter our circulation.
Lectins are problematic because they are sticky molecules that can bind to the linings of human tissue, especially intestinal cells. In so doing, they disable cells in the GI tract, keeping them from repairing and rebuilding.1 Therefore, lectins can contribute to eroding your intestinal barrier (leaky gut).
Because the lectins also circulate throughout the bloodstream they can bind to any tissue in the body — thyroid, pancreas, collagen in joints, etc.2 This binding can disrupt the function of that tissue and cause white blood cells to attack the lectin-bound tissue, destroying it. This is an autoimmune response. The lectins in wheat for example, are specifically known to be involved in rheumatoid arthritis.
