Onions are vegetables that are also known as common onions or bulb onions. Onion is a member of the same genus as garlic, shallots, leeks, and chives, which is allium. And all of these vegetables contain a variety of vitamins, minerals, and powerful plant chemicals that are beneficial to health in a variety of ways. Onion benefits for men, in particular, are receiving more attention.

As previously stated, a bulb onion is nothing more than a short stem with fleshy leaves. It serves as a food reserve for the plant, allowing it to survive in harsh weather conditions.

The most negative aspect of the onion is definitely that it makes us cry, but otherwise, it is a true nutritional treasure and an integral part of our gastronomy. It hides many nutrients and medicinal properties under its layers, minerals, and trace elements (calcium, magnesium, chlorine, cobalt, copper, iron, phosphorus, iodine, nickel, potassium, silicon, zinc, sulfur, and bromine). it is also found in vitamins (A, B, C, and E).

Onions contain a volatile sulfur essence that gives them their unique spicy flavor. One of these ingredients dissolves quickly in water to produce sulfuric acid, which causes tears when cut.

In addition, onions contain a volatile substance called allyl, which has a bactericidal and sterilizing effect. It is also called “vegetable insulin” due to its interesting content of glucokinase, a substance that lowers blood sugar levels. For all these reasons, the Spanish Nutrition Foundation recommends its consumption, emphasizing its diuretic and antiseptic properties.

It is very versatile in the kitchen and the best way to reap the benefits of onions is to eat them raw. You won’t lose much.

When buying onions, you need to choose ones with firm bulbs, no sprouts, and intact skins. To store them, they should be kept in a dry, well-ventilated place and prevented from accumulating.


 Onions are a source of dietary fiber that contributes to the intake of soluble dietary fiber. The type of fiber found in onions may reduce the risk of cardiovascular diseases such as high blood pressure, stroke, heart failure, and heart attack. In addition, according to the Spanish Heart Federation, it helps lower cholesterol levels.


100 grams of onions provide 11.5% of your daily recommended amount of vitamin B6. Vitamin B6 helps the body produce serotonin and myelin, so onions are good for cognitive and neurological function. Additionally, one serving of onion provides 5.9% of the recommended daily allowance of folic acid and 3.9% of the vitamin C your body needs.

Slicing onions make you cry because the onion emits a sulfur-based gas when cut. Sulfuric acid is formed when the gas reacts with the water in your eyes. Your tear ducts work overtime to clear your eyes of this fiery irritant. If you want no more (or fewer) tears, move your face away from the onion so the gas dissipates before it reaches your eyes.

Another tip for reducing tears is to chill the onions for 30 minutes first. Then, cut off the top and peel the outer layers away from the root end, leaving the root end intact.

Bulb onions are available in yellow, red, or white. Yellow onions account for approximately 87 percent of the commercial onion crop in the United States; red onions account for 8 percent, and white onions account for 5%.

Scallions, also known as green onions, are immature yellow, red, or white onions harvested before the bulb forms. Immature onions are also known as “spring onions” and “salad onions.”

A scallion is not the same as a shallot. This is most likely because “échalion” is another name for shallot, derived from the French échalote. Shallots have a distinct flavor, but it is more similar to that of mature onions than to that of scallions.

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.

The flavonoids in red onions can contribute to heart health. Onions are also rich in organosulfur, which can help prevent heart disease.

One of the sulfur compounds in onions and quercetin can have beneficial effects on blood sugar. However, it was found that onions exhibited a positive effect only when taken along with metformin, the antidiabetic drug.

 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.

You can strain the juice once, and using a medicinal dropper, pour a few drops of the juice into your infected ear.

You can also place onion packs on the infected ear. Though the remedy is not scientifically proven, some people believe it might work.

The selenium in onions supports vitamin E in the eye (which protects the cells in the eye).

Prevent Blood Clots

Onions contain a compound called rutin, which can help prevent blood from clotting. In numerous mice studies, it was found to be the most potently anti-thrombotic compound.
