In this episode of The Exam Room, Dr. Hana Kahleova joins Chuck Carroll breaks down the science behind onion health benefits and explains how this humble vegetable may protect your heart, improve blood sugar, reduce liver fat, and even support longevity.

Here’s what the science says about onion health benefits:

  • Red onions may reduce liver fat by more than 16% in just 12 weeks
  • Onions can improve insulin sensitivity and lower post-meal blood sugar
  • Quercetin in onions may reduce inflammation and oxidative stress
  • Onion compounds help support nitric oxide and healthy blood flow
  • Higher intake of onions and garlic is linked to lower cardiovascular and colon cancer risk

Dr. Kahleova explains how onions work inside the body — from protecting your arteries to supporting metabolic health — and why frequency matters more than eating large amounts at once.

Whether you love onions or pick them off your plate, this episode will change how you see their health potential.

This episode is powered by Menopause Makeover from Drs. Brooke Bussard and Dr. Samone Zarabi. Reclaim your body, your life, and your confidence.
