Scientific observations suggest that quercetin and sulfur-containing compounds in onions may:
Support insulin sensitivity
Slow rapid carbohydrate absorption
Help regulate post-meal glucose spikes
These effects are believed to occur through natural mechanisms such as:
Inhibition of digestive enzymes like α-glucosidase
Support of pancreatic function
Reduction of oxidative stress linked to blood sugar imbalance
👉 Important note: Red onions contain higher quercetin levels than white or yellow onions, making them especially interesting for those seeking natural dietary support.
What Scientific Research Suggests
Several studies have explored onion consumption in relation to metabolic health:Research reviews indicate that quercetin and organosulfur compounds may support insulin secretion and glucose uptake by cells.
