About Cooked onions
Cooked onions are a staple ingredient in cuisines worldwide, including French, Indian, and Mediterranean cooking. Originating in Central Asia, onions are one of the earliest cultivated crops. When cooked, their sharp flavor mellows and becomes sweet due to the caramelization of natural sugars. Nutritionally, onions are low in calories (~40 kcal per 100g cooked), contain small amounts of fiber (1.4g) and provide vitamins such as vitamin C, B6, and folate, along with minerals like manganese. They are also rich in antioxidants, particularly quercetin and sulfur compounds, which contribute to their health-promoting properties.
Health Benefits
- Supports immune function due to vitamin C content (4.7mg per 100g cooked).
- Potential anti-inflammatory effects from quercetin, a powerful antioxidant found in onions.
- Heart health benefits through sulfur compounds, which may help regulate cholesterol levels.
- Supports digestive health due to small amounts of soluble fiber and prebiotic compounds like inulin.
- May aid blood sugar regulation due to chromium, which helps enhance insulin function.
