They also contain Vitamin B6, crucial for brain development and function, and folate, essential for cell growth and development, particularly important during pregnancy. Furthermore, yellow onions are a good source of potassium, a mineral vital for maintaining healthy blood pressure.

A medium yellow onion typically contains around 40 calories. This makes it a low-calorie, nutrient-dense food, perfect for incorporating into a healthy diet. This low-calorie count, coupled with its abundance of vitamins and minerals, makes it a great addition to weight management plans.
What are the Health Benefits of Eating Yellow Onions?
The health benefits extend beyond individual vitamins and minerals. The various compounds found in yellow onions contribute to several health advantages:
-
Antioxidant Properties: Yellow onions are rich in antioxidants, which combat free radicals, protecting cells from damage and reducing the risk of chronic diseases. This includes quercetin, a powerful flavonoid with potent anti-inflammatory and antioxidant effects.
-
Improved Heart Health: Studies suggest that regular consumption of yellow onions may contribute to better heart health by reducing cholesterol levels and blood pressure. The quercetin content plays a significant role in these cardiovascular benefits.
-
Anti-inflammatory Effects: The anti-inflammatory properties of yellow onions can help reduce inflammation throughout the body, potentially alleviating symptoms of conditions like arthritis.
