Origin of onions
Onion (scientist Allium Cepa) belongs to the plants of the genus Allium, family Alliaceae, which also includes garlic, leeks, etc.
It is one of the oldest cultivated vegetables known to man (it did not spoil easily, it was easy to transport, and suitable for canning by drying).
It probably originated in the Middle East and Asia. From the distant past, it was used for various medical purposes, fighting colds, flu, and various other diseases.
As we have said, due to its specific taste characteristics (taste and smell), it is widely used in every kitchen. Onion is used as a base for recipes, as a side dish, spice, but also in various salads and cream salads.
It can be found in fresh, frozen, canned, and dried forms in the markets. Depending on the type, there may be different flavor intensities, from the strongest to the mildest.
Red onions have a slightly milder taste, while yellow (white) has a slightly sharper taste. The well-known “crying” caused by onions is due to the flavonoid sulfur components released during cutting.
That is, during the “destruction” of its cells in whose membranes these components are located.

11 Benefits of onions for health
1. Powerful antioxidant effect
Antioxidants are the body’s defense mechanism against free radicals – harmful components that are constantly produced as metabolic waste in the body and oxidatively damage its various cells and tissues.
The body has mechanisms to produce a certain percentage of necessary antioxidants, but it still depends on the intake.
Permanent oxidative damage leads to processes of chronic inflammation or inflammation, which in the long run is one of the main reasons for the development of chronic diseases.
Red onions generally contain anthocyanins – special plant pigments (giving it a red color) from the group of flavonoid antioxidants.
Many studies have linked these antioxidants to better heart health.
For example, a study of more than 43,000 male volunteers found that those who took at least 600mg of anthocyanins daily had a 15% lower risk of a fatal heart attack.
Another study found a similar effect in women.
Anthocyanins have also been linked to anticancer effects.
In addition, different types of onions contain over 25 other types of flavonoid antioxidants of which the most famous and in the largest amount is quercetin (onion is the best source of this potent antioxidant).

2. Great food for a healthy heart
The aforementioned flavonoid antioxidants, which are rich in different types of onions, can reduce chronic inflammation.
This is achieved through the fight against free radicals and the action to more successfully reduce blood fats and cholesterol.
Both effects are particularly important in reducing the risk of a range of cardiovascular diseases.
The powerful anti-inflammatory properties of onions can also reduce blood pressure, as well as prevent unwanted blood clots.
This has been demonstrated by a number of scientific studies.
In addition, potassium and fiber – components that are present in solid amounts in onions – have a certain positive effect on heart health.
Studies show that optimal potassium intake leads to a reduced risk of heart attack and stroke (lowers high blood pressure) and prevents muscle and bone loss.
This vegetable also contains a certain amount of magnesium, which is also good for heart health.
Fiber has been linked in a number of studies to low total blood cholesterol.
3. Onion is food for weight loss and digestive health
As we have seen, onions are really low in calories. This makes it great for adding to a healthy weight loss diet.
Also, something that is very important for the weight loss process – onions contain excellent amounts of fiber. Fiber is food for the intestinal microflora and helps in the gradual digestion of food.
This gradual digestion leads to the gradual release of glucose into the bloodstream, which keeps us full for a long time.
In addition, they can contribute to faster and longer satiety by binding free water in the stomach.
So, onions are rich in prebiotics from which the beneficial intestinal microflora can create short-chain fatty acids – acetate, propionate, and butyrate.
Numerous studies have linked these fatty acids to better digestive health, stronger immunity, reduced inflammation, improved mineral absorption (which is especially good for bone health), and so on.
Fiber also helps with one of the most common digestive health problems – constipation.
Research shows that increasing the amount of fiber in the body reduces the chances of developing colorectal cancer.

Additionally, there are numerous animal studies that provide similar data.
Such antidiabetic effects are thought to be due to the flavonoid antioxidants in onions, such as quercetin and other sulfur components.
5. Fights tumor processes
