Lectins: Eat or avoid?

What is a Lectin?

Lectins are molecules found in beans, peanuts, soybeans, lentils, and wheat. Lectins can bind to human tissues if we have a compromised gut barrier (I don’t love the term leaky gut but it helps us understand the concept here).

Once a lectin is bound to your body’s tissues, your immune system sees it as a “red flag” and mistakenly mounts an attack against those tissues. This attack is better known as autoimmunity, and can be part of what causes autoimmune disease. Wherever we see an attack, we see inflammation, and often pain and dysfunction in that area of the body.

Lectin-associated autoimmune symptoms are most frequently seen as joint pain / rheumatoid arthritis, and intestinal barrier disorders Crohn’s disease, ulcerative colitis, Celiac disease, SIBO, and IBS.

How do I know if I should avoid lectins?

There are two ways to know if lectins are contributing to symptoms:

  1. Do a Food Intolerance Test to see if there is an immune system response to lectin-containing foods. If one comes up and symptoms are severe, I typically remove all lectin-family foods.
  1. Remove lectins (along with other food triggers) and see if symptoms improve. This can take up to 3 months for full resolution, but we typically see improvement within 2-4 weeks.

Lectins are just a small part of addressing digestive concerns. Book an appointment to address the intestinal barrier, microbiome and other food triggers as part of your overall plan to get your digestive health back on track.
