The secret to onion’s strength lies in its rich concentration of bioactive compounds, including organosulfur compounds, flavonoids (like quercetin), and essential micronutrients .
· Heart Health & Circulation: The flavonoids and sulfur compounds support heart health by helping to lower blood pressure, reduce LDL (bad) cholesterol, and improve blood circulation .
· Blood Sugar Regulation: Onions may help regulate blood sugar by improving how the body processes glucose and responds to insulin .
· Immunity & Fighting Infection: Onions are a good source of Vitamin C and contain compounds with antibacterial properties that help fight harmful bacteria .
· Antioxidant Protection: Powerful antioxidants help detoxify the body and protect the heart by reducing inflammation and fighting oxidative stress that can lead to chronic disease .
Research even shows that the often-discarded onion peels possess high antioxidant and antimicrobial activity . To get the most benefits, use the whole onion when cooking (e.g., adding the skin to stocks).
