Are There Any Side Effects?
For most people, green onions are completely safe. However, in certain cases, they may cause mild issues:
• Gas or bloating due to fiber and natural plant sugars
• Heartburn in people prone to acid reflux
• Allergic reactions (rare)
• Interaction with blood-thinning medications because of vitamin K content
People with sensitive stomachs or digestive conditions like IBS may notice discomfort after eating raw green onions.
Do Green Onions “Cause” Disease?
There is no credible medical evidence that green onions cause disease when consumed in normal amounts. In fact, they are generally considered a healthy addition to a balanced diet.
The Bottom Line
Eating green onions typically supports overall health rather than harms it. As with any food, moderation is key. If you have specific health conditions or take medication, it’s always wise to consult your healthcare provider before making major dietary changes.
For most people, green onions are both safe and beneficial.
