The Claim
Structural similarity between dietary lectins and thyroid antigens, in the presence of intestinal barrier disruption, leads to the production of cross-reactive autoantibodies targeting thyroid tissue.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When the gut barrier is compromised, certain proteins in food called lectins that resemble thyroid proteins may trigger the immune system to produce antibodies that mistakenly target the thyroid gland.
See the scientific wording
Structural similarity between dietary lectins and thyroid antigens, in the context of intestinal barrier disruption, can induce cross-reactive autoantibody production against thyroid tissue.
What the research says
1 studyStudy: Reaction of Lectin-Specific Antibody with Human Tissue: Possible Contributions to Autoimmunity
This study found that antibodies made against certain food proteins (lectins) can accidentally stick to human tissues, like they’re confused with the body’s own parts. This could explain why some people’s immune systems start attacking their thyroid, especially if their gut is leaky.
