4. Regulating Blood Sugar
According to research at the American Diabetes Association, the onion is effective at controlling the development of type 2 diabetes. This condition is caused by retention of sugars in the blood. The sugar in your blood is metabolized by insulin that is secreted from the pancreas. Diabetes is caused when the pancreas can not produce enough insulin. The onion contains chromium, an essential ingredient that will help the pancreas to function more efficiently. The chromium that is present in the onion naturally treats the insulin deficiency in diabetes, and because of the low glycemic index in the onion, they are safe for diabetics to consume too.
5. Boosting Immune System
Your immune system works to protect the body from diseases and outside ailments. The onion contains polyphenol compounds, giving them powerful antioxidant properties. The benefit on the body of all those antioxidants is that they can easily remove the free radicals from the body and make the overall defense system stronger. Consuming onions will help the body to better defend against pathogenic attacks, and can even lower the levels of histamine in the body to reduce the violent reactions of the body to certain airborne allergens.
6. Promoting Strong Bones
In research that was conducted by the National Osteoporosis Foundation, the onion can help to improve bone density in those suffering from osteoporosis and osteoarthritis. Senior women especially who suffer from these post-menopausal hormonal imbalances that began consuming more onions had a better bone density than those who did not include the onions in their diet. The healing power of the onion also appeared to help reduce the likelihood of dangerous bone conditions like hip fracture.
