What Is The History Of Onions?
The ancient origin of onions spans the western and eastern parts of Asia. There are numerous species of onions found the world over, which basically means they were cultivated across the world probably at the same time. Records suggest that onions started to be used in China way back in 5000 BC – more so because of the bulb’s durability to transport and store. Ancient Egyptians were known to revere the vegetable, considering its spherical shape and concentric rings a symbol of eternal life. In fact, onions were also used in ancient Egyptian burials.
The medical documents of Charaka Samhita (way back in the 6th century BC) mention onion as a medicinal plant. Even a Greek physician from the 1st century AD (Dioscorides) documented the vegetable’s medicinal uses. And it was the first European settlers who had taken onions to North America.
The Variety Of Onions
Onion is so widely used that any culinary dish from almost any part of the earth has the vegetable added to it. No doubt there are several types of onions – but here, we talk about the most common ones.
Yellow onions – They have ivory white flesh that is surrounded by heavy brown skin. They have a strong and sulfur-like aroma.
Sweet onions – They have a lighter, less-opaque skin that surrounds a larger and slightly fatter body of the vegetable.
White onions – They have a papery white skin, and they are milder and sweeter than their yellow counterparts.
Red onions – They are mild and sweet enough to be eaten raw. The exterior skin and flesh are a deep magenta.
Shallots – They are smaller and brown-skinned and have purple flesh.
Green onions – They are the immature onions that haven’t yet formed a bulb.
Leeks – They are shaped like overgrown scallions (the long-necked onion with a small bulb) and are usually used in sauces and soups.
What Are The Health Benefits Of Onions?
1. Fight Cancer
As per a study conducted by the University of Guelph, red onions are the most effective in destroying breast and colon cancer cells. These onions have high levels of quercetin and anthocyanin – two compounds that contribute to this characteristic. Onions activate the pathways that provoke the cancer cells to kill themselves. They make the environment unfavorable for cancer cells to communicate, and this inhibits their growth.
It was also found that people with the highest consumption of onions had the lowest cancer rates. As a preventative measure, you can have your burgers garnished with red onions.
2. Improve Heart Health
The flavonoids in red onions can contribute to heart health. Onions are also rich in organosulfurs, which can help prevent heart disease. According to one Argentine study, intake of the organosulfur compounds found in onions can cut the risk of cardiovascular disease. Onions contain thiosulfinates that act as natural blood thinners and reduce the risk of heart attack and stroke.
The quercetin in onions also has the potential to fight heart disease. It offers both antioxidant and anti-inflammatory properties that promote heart health. Onions are also a part of the French Paradox – they are an important part of French cuisine and are thought to be responsible for the low incidences of heart disease among the French despite their high-calorie diet.
Onions can also improve cholesterol levels, and this ultimately benefits the heart. As per a report by the Cambridge University Press, the flavonoids in onions help lower the levels of LDL (the bad cholesterol) in obese people.
Onions also prevent the blood platelets from sticking each other, which can lead to clotting and eventually, heart attacks. They also can prevent high blood pressure, thereby averting heart danger. Another study on rabbits showed that onions could prevent atherosclerosis. They achieve this by enhancing fibrinolytic (a process that results in the removal of small blood clots) activity.
3. Lower Blood Sugar Levels
One study has proven that onion extract can help lower blood sugar levels. The study was conducted on diabetic rats, and the results were encouraging. One of the sulfur compounds in onions (S-methylcysteine) and quercetin can have beneficial effects on blood sugar. However, it was found that onions exhibited the positive effect only when taken along with metformin, the antidiabetic drug.
In yet another study, polyphenols (especially the ones in onions) were found to play a role in glycemic control.
4. Promote Healthy Digestion
The digestive benefits of onions can be attributed to inulin, a fiber present in the vegetable. Inulin acts as a food source for the beneficial bacteria in the intestines. Consuming this fiber helps your body maintain good levels of the healthy bacteria. However, the thiosulfinates in onions can cause harm to these beneficial bacteria (as they have antibacterial properties). Hence, if you are sensitive to the antibacterial properties of onions, do consult your doctor.
Another soluble fiber in onions, oligofructose (which is a sub-group of inulin), was found to prevent and treat different types of diarrhea. And the phytochemicals in onions can cut the risk of gastric ulcers.
The natural prebiotics in onions can also help ease constipation. They are also believed to help treat stomach ache and stomach worms, though more research is warranted.
Onion is known to cause migraine and flatulence in some people. Consult your doctor if this happens.
5. Maintain Bone Health
Preliminary research suggests that onions can prevent age-related osteoporosis. According to Swiss researchers, a compound in white onions (called GPCS) can reduce bone loss. Though the study was conducted on rats, it does hold promise for humans.
Another study revealed that women who ate onions regularly had 5 percent more bone mass than those who ate less. Onion consumption was also found to have a beneficial effect on the bone density of women older than 50 years.
According to the Arthritis Foundation, quercetin in onions can inhibit the activity of leukotrienes, prostaglandins, and histamines (all of which cause inflammation) in osteoarthritis and rheumatoid arthritis. Onion intake was also found to help treat joint pains.
6. Prevent Inflammation And Other Allergies
We have already seen quercetin (and other flavonoids) in onions can help prevent inflammation. Onions also treat allergies by preventing the cells from releasing histamine.
