About Brown onion
Brown onions are a type of dry onion commonly used in cooking due to their strong flavor, which mellows and sweetens when cooked. Originating from central Asia, they are now widely cultivated and featured in cuisines worldwide, including European, Asian, and American. Nutritionally, brown onions are low in calories—only about 44 calories per 100 grams—and are rich in dietary fiber, vitamin C, and several phytonutrients such as quercetin. They primarily consist of water (89%), carbohydrates (9%), and trace amounts of protein and fat. Their sulfur-containing compounds contribute to their characteristic pungency and potential health benefits.
Health Benefits
- Supports immune health due to vitamin C, which acts as an antioxidant and promotes collagen synthesis.
- May reduce inflammation and enhance cardiovascular health due to quercetin, a flavonoid abundant in brown onions.
- Improves digestive health as they are a source of prebiotic fibers, such as inulin, which feeds beneficial gut bacteria.
Dietary Considerations
Selection and Storage
Store whole brown onions in a cool, dry, and ventilated place away from potatoes to prevent premature spoilage. Once cut, refrigerate in a sealed container for up to 7 days.
