Onions are not only seasonings, they also appear to be healthy. The ancient Greeks were already aware of this. They used it as an aid for the flu and colds. But what are the health benefits of an onion today? Why are onions so healthy?

Onions are full of good nutrients

There are many different healthy nutrients in an onion. Onions, for example, are rich in vitamin C. Vitamin C has an antioxidant function in the body and is necessary for: the formation of connective tissue, the absorption of iron and the maintenance of the resistance.

In addition, onions contain sulfur components, flavonoids and antioxidants that are good for your body and your skin. Onion is also high in polyphenol, in the form of quercetin. Quercetin is an antioxidant that has beneficial properties for the heart and blood vessels. In addition, quercetin promotes the effect of vitamin C. It also contains quite a bit of B6 and B11.
Minerals such as iron , chromium, molybdenum, manganese and potassium are also present in the onion.

Health Benefits of onions

1.Good for heart and blood vessels

According to the British Institute of Food Research, onions are particularly good for the heart. This is due to the active ingredient quercetin, which is also found in apples, red wine and tea. It prevents chronic inflammation and thickening of the blood vessels. Inflammation is an important cause of clogging of blood vessels. In addition, onions are rich in sulfur components that can lower cholesterol and fat levels in the blood.

2. Positive in diabetes

Thioproanal-s-oxide, is the substance in onions that induce the well-known tears. This counteracts the breakdown of insulin in the liver and possibly also stimulates the production of insulin in the pancreas. There are also other blood sugar lowering substances, such as glucoquinines, present. This blood sugar drop would only happen in diabetics and not in healthy people. An English study showed that the consumption of onions lowered the glucose level in the blood in diabetes II patients.

3. Good for the resistance

Onions are thus rich in vitamin C, a powerful anti-inflammatory substance. This improves the resistance. The production of interferon (natural protein secreted in the cells of the immune system after contact with viruses, bacteria or fungi) gets a boost from onions. This promotes phagocytosis, the process by which a harmful substance is taken up and digested by a cell. This process plays a nourishing and defensive role in cell functions. Which all together improves your resistance.

4. Beneficial effect on bone density

Small-scale research has shown that onions have a beneficial effect on bone density. Over time, the bones became stronger and the risk of bone fractures decreased as a result of eating onions.

5. Cancer protection

There is also enough of the powerful antioxidant organosulphur in an onion. This component is regularly associated with a lower risk of cancers such as: prostate cancer, kidney cancer, oral cancer, breast cancer and colon cancer. Several studies showed a significant reduction in cancer from the use of garlic and onion. This is not to say that onions are a cancer drug. However, eating onions every day could reduce the risk of developing cancer and the very early stages of cancer.

Since onions are considered a natural antibiotic, they can also help prevent cavities. Cavities and tooth decay are mainly caused by bacteria that we have in the mouth. Certain bacteria have been shown to dislike the antibiotic effect of the onion.

6. For young skin

The presence of antioxidants inhibits the aging of the skin. However, young skin can also benefit from onions. Thanks to its antimicrobial, antibacterial and anti-inflammatory properties, it could curb acne.

7. Improves sperm quality

A study done on rats showed that the rats that had been given onion juice had a higher sperm concentration. In addition, the number of viable sperm seeds had also increased. So onions could improve the quality of sperm.

8. Helps against asthma

The sulfur components in onions are also said to have an anti-inflammatory effect. They would inhibit the production of thromboxanes, which cause inflammatory reactions. It also prevents the clumping of platelets. The thiosulfates and cepaenes have an inhibitory effect on a number of enzymes in the body, cyclooxygenase and 5-lipoxygenase, which are partly responsible for inflammation and asthma attacks.

Conclusion

Many studies on the health effects of onions have been conducted on animals. Most people add onion to the dish, which also contains other vegetables. This makes research into the long-term effects of eating onions difficult. These effects could also be caused by other vegetables. However, almost all studies show that eating onions is positive for health. But as with all food, it is wise to eat a varied diet.
