⚠️ But Onions Can Also Cause…

Gas

Bloating

Stomach discomfort
Especially in people with IBS.
🔥 Heartburn or Acid Reflux
Raw onions can relax the lower esophageal sphincter, potentially worsening reflux symptoms in sensitive individuals.
😢 Tearing Eyes
When cutting onions, sulfur compounds are released that irritate the eyes — harmless but annoying!
