That’s another incomplete clickbait headline. It doesn’t actually tell you what condition onions are supposed to “cause,” which is a common trick used to get people to tap “See more.”
In reality, onions (Onion) are generally safe and healthy for most people when eaten as part of a normal diet.
What onions actually do in the body
Onions contain:
- Antioxidants (like quercetin)
- Prebiotic fiber (good for gut bacteria)
- Anti-inflammatory compounds
So they are often associated with health benefits, not harm.
Possible minor issues (in some people)
Onions can cause:
- Gas and bloating (especially raw onions)
- Heartburn or acid reflux
- Digestive discomfort in people with IBS (they’re high in FODMAPs)
What they do NOT cause
Onions do not:
- Damage organs
- “Toxify” the body
- Cause serious disease in healthy people
- Require avoidance for most individuals
Bottom line
These “doctors reveal onions cause…” posts are usually exaggerations or misinterpretations of minor digestive effects in sensitive individuals.
If you want, you can paste the full “see more” text—I can break down exactly what’s true and what’s misleading.
