đŤ Oats Are Not the Enemy. Letâs Stop With the Nonsense.
I keep hearing that oats are âtoxicâ because of lectins.
This idea has largely been popularized by Steven Gundry.
Cardiologist or not â that claim is simply wrong.
Letâs apply basic physiology.
1ď¸âŁ Oats are not high-lectin foods.
2ď¸âŁ Cooking denatures lectins (oats are steamed and boiled).
3ď¸âŁ Epidemiology consistently shows oat intake improves LDL, ApoB, insulin sensitivity, and inflammatory markers.
4ď¸âŁ Beta-glucan in oats improves gut microbiome diversity and reduces cardiovascular risk.
If oats were inflammatory, we would see:
Higher CRP
Higher autoimmune rates
Worse metabolic panels
We see the opposite.
Are there individuals who may not tolerate oats?
Absolutely. Thatâs personalized medicine.
But blanket statements that oats are âpoisonâ?
Thatâs not evidence-based. Thatâs marketing.
Functional medicine should be rooted in physiology, not fear.
If we eliminate foods, it should be because labs, symptoms, and mechanisms support it â not because someone needed a villain for a book.
The transformation begins with thinking critically.
