🌿 Why Onions Are a Natural Ally for Blood Sugar
Red onions are not just a kitchen staple — they’re also packed with powerful plant compounds that can help balance blood sugar levels and improve insulin sensitivity.
🔬 What Studies Say:
- Onion Extract & Diabetes:
A 2014 study published in the Journal of Medicinal Food found that onion extract significantly lowered blood glucose levels in diabetic rats, suggesting similar benefits in humans. - Quercetin’s Role:
Onions are rich in quercetin, a flavonoid that helps reduce inflammation and improve insulin resistance. A 2011 study in Phytotherapy Research confirmed that quercetin supplementation improves glycemic control. - Sulfur Compounds & Chromium:
Onions also contain organosulfur compounds and chromium, both known to support glucose metabolism and lower fasting blood sugar.
