Do Onions Contribute to Your 5-A-Day?
Yes, onions are officially counted as a portion of your 5-A-Day. For the purpose of the 5-A-Day initiative, a single portion of onions is defined as 80 grams. This rule applies to both cooked and raw onions, meaning that adding them to a stew, salad, or sandwich can help you reach your daily target with ease. The 5-A-Day campaign, endorsed by health organizations like the World Health Organization (WHO), encourages consuming a minimum of 400g of fruit and vegetables daily to support overall health and reduce the risk of serious illnesses. As a member of the Allium genus, related to garlic and leeks, onions are a versatile and nutritious vegetable that can be incorporated into a wide variety of meals.
Nutritional Breakdown of Onions
Beyond their contribution to your 5-A-Day, onions offer a robust nutritional profile. They are low in calories but rich in vitamins and minerals, including vitamin C, vitamin B6, folate, and potassium.
- Vitamin C: Acts as an antioxidant, supports immune function, and is crucial for skin health.
- Folate (B9): Important for cell growth and metabolism.
- Vitamin B6: Involved in red blood cell production.
- Potassium: Helps regulate fluid balance and heart function.
Additionally, onions are packed with beneficial plant compounds and antioxidants. Red and yellow onions are particularly rich in antioxidants, with yellow onions potentially having up to 11 times more than white varieties. They also contain organosulfur compounds, which contribute to their potent flavour and offer various health-protective properties.
Health Benefits of Incorporating Onions
Regularly including onions in your diet can support several aspects of your health. Research has linked their consumption to a variety of positive outcomes.
- Cardiovascular Health: The antioxidants and organosulfur compounds in onions can help lower blood pressure, reduce cholesterol, and inhibit blood clot formation, which lowers the risk of heart disease and stroke.
- Blood Sugar Regulation: Studies, primarily in animals and observational human trials, have shown that onions can help lower blood sugar levels, potentially by boosting insulin production.
- Bone Density: Observational studies have found a link between consistent onion consumption and increased bone density, particularly in older women.
- Gut Health: Onions contain prebiotics like fructans and inulin. These non-digestible fibres feed the beneficial bacteria in your gut, supporting digestive health and potentially boosting immunity.
- Anticancer Properties: Increased consumption of allium vegetables, including onions, has been associated with a reduced risk of certain cancers, such as stomach and colorectal cancer.
