A gluten-free diet is healthier for everyone
The evidence
Gluten-free is a medical fact for celiac disease (~1%), but Lebwohl 2017 (BMJ, 110k) shows no cardiovascular benefit for those without it — and gluten-free packaged foods are often lower-fiber, higher-sugar.
The mechanism, in brief
For people without celiac disease, wheat allergy, or diagnosed NCGS, does a gluten-free diet provide health benefits? The evidence is clear: no.
