Onion belongs to the family of onion-like plants and is rich in compounds that contain sulfur, which is responsible for its strong odor and many of its properties for good health.
Cardiovascular System
There is evidence that compounds which containing sulfur act against clogging of the blood vessels and blood clotting. Sulfur compounds actually enhance the work of the blood vessels and can affect and reduce the level of cholesterol and triglycerides. Intake of onions in the diet can affect the prevention of heart attack and its high levels of flavonoids are in favor of this conclusion.
Bones Strength
Studies have shown that onions can increase bone strength, which is especially good for women who go through menopause. Since bones weaken during menopause and remain weak after that period, onion is good for women who have already been through this period because it reduces the risk of hip fractures.
Studies have shown that only regular consumption of onion can highlight these positive features. Women who consumed onion once or twice a month their bone strength did not increased. High sulfur levels can affect the cartilage, because it is made of tissue which needs sulfur to form.
Anti-inflammatory
Sulfur molecules which are part of the onions structure stimulate activity of macro phases – specific white blood cells that play a major role in the immune system. Namely they are obliged to react in the body when inflammation occurs. Onion is rich in antioxidants, which are also good at fighting inflammation.
Prevention of C ancer
It was shown that onions have a stake in reducing the risk of several types of cancer (colon, ovarian and vocal cords), even when consumed in moderate doses. However, to fully exploit the benefits of the onion, you need to consume at least one whole cooked onion into your meal or to eat half a clove of fresh onion daily.
Other benefits
Onion is known to maintain the balance of blood sugar. Also because of the presence of flavonoids, onion acts preventively against bacterial infections or prevent further expansion of the same.
