Every evening, my grandmother would peel a fresh red onion before preparing dinner.
One day, I noticed she held half of it near her face for a few moments before slicing the rest.
Curious, I asked why.
She smiled and said,
“It’s an old family tradition. The fresh aroma always made me feel refreshed after a long day.”
Later, I mentioned this habit to my eye doctor.
He smiled and replied,
“Red onions are naturally rich in quercetin, anthocyanins, sulfur compounds, and vitamin C. While their aroma may stimulate tearing and temporarily help wash away surface irritants from the eyes, they’re best appreciated as part of a healthy diet rich in colorful vegetables that supports overall eye wellness.”
That conversation made me appreciate this humble vegetable even more.

Red onions naturally contain:
- Quercetin
