Lectin-Free Diet by Dr. Steven Gundry

Dr. Gundry's Lectin-Free Diet makes its strongest claim by branding common plant compounds as toxins, but evidence refutes this. A 2019 systematic review showed that cooking neutralizes over 95% of lectins in beans and grains, rendering them harmless. Canned beans cost just $1 per serving, while Gundry's recommended foods can triple grocery bills, making this theory expensive and nutritionally suspect.
