Introduction Of Complete Guide About Onions Health Benefits Risks And Facts

Complete Guide About Onions Health Benefits Risks And Facts. According to a nutritionist at the Fitness Institute of Texas at the University of Texas in Austin, “onions are a super-healthy food.”. It is a good source of vitamin C as well as sulphuric compounds, flavonoids, and phytochemicals.

There are naturally occurring substances in fruits and vegetables that may interact with the human body and cause healthful responses. These compounds are called phytochemicals or phytonutrients. Many fruits and vegetables’ colors may be attributed to flavonoids. For Parkinson’s disease and cardiovascular disease, they seem to have a protective effect.

Onion quercetin, an antioxidant that may help prevent cancer, is an important flavonoid in onions. Although additional research is needed, registered dietitian nutritionist and Academy of Nutrition and Dietetics spokeswoman Angela Lemond believes it may have heart-health advantages as well.

University of Maryland Medical Center says quercetin may also help with symptoms of bladder infections, improve prostate health, and even reduce blood pressure. Phytochemicals such as disulfides, trisulfides, cepaene, and vinyldithiins are found in significant quantities in onions. According to the National Onion Association, all of them are healthy for your health and contain anticancer and antibacterial characteristics.

According to the journal Phytotherapy Research, onions are one of the most important sources of antioxidants in the human diet because of their widespread usage in cooking. Onions’ characteristic sweetness and scent are a result of their high concentrations of antioxidants. “Antioxidants and amino acids are found in foods strong in antioxidants,” stated Lemond. “Damage and cancer are both prevented by antioxidants. Every cell in the body relies on protein, and amino acids are the building blocks of protein.”

Onion sulfides include amino acids that are essential for human health. When it comes to creating cell architecture and synthesis of proteins sulfur is one of our body’s most prevalent minerals.

“I prefer to suggest onions because they give taste without salt and sugar,” Jarzabkowski remarked. Onions are low in calories (45 per serving), low in salt and free of fat or cholesterol. They are also a good source of vitamin C. Onions are also high in fiber and folic acid, a B vitamin that aids in the production of new, healthy cells in the body.

It doesn’t matter whether you eat your onions raw or cooked; the organic sulfur compounds in raw onions give various health advantages, as the BBC reports. The outer layers of onion flesh have a high concentration of flavonoids, according to a study published in the Journal of Agricultural and Food Chemistry. As a result, while peeling the onion, take care to remove as little of the edible section as possible.

Keeping Your Heart Healthy

Onions, according to Jarzabkowski, help to keep the heart healthy by decreasing blood pressure and reducing the chance of a heart attack. Studies have shown that sulfur works as an anticoagulant and stops blood platelets from adhering together. A heart attack or stroke is more likely when platelets congregate. Sulfurs in garlic were the topic of a previous study published in Thrombosis Research in 1992. In addition, animal research published in the Journal of Hypertension in 1987 showed that consuming sulfur delayed or decreased the development of hypertension. Whether or if this advantage can be seen in people, according to the scientists, would need more study.

Oxylipins, a kind of messenger molecule, has recently been linked to the control of excessive cholesterol. According to a study published in the journal Redox Biology, onions boost oxylipin levels, which aid in controlling blood fat and cholesterol levels.

According to the University of Maryland Medical Center, the quercetin in onions may also help prevent plaque building in the arteries due to rising cholesterol levels, hence lowering the risk of heart attack and stroke.

Onions were studied for their hyperlipidemic (cholesterol-lowering) properties in a research published in Pharmacy & Pharmacology International Journal. For two months, researchers monitored volunteers who were instructed to take a daily 200g serving of onions. The overall cholesterol levels of 35 out of the 40 subjects were found to be considerably lower after the research. When it comes to cardiovascular disease, “we concluded from our research that Onion and Ginger decrease risk through reducing plasma total cholesterol and LDL [low-density lipoprotein].”


According to a 1990 research published in the International Archives of Allergy and Applied Immunology, sulfur compounds in onions may be efficient anti-inflammatory agents.

According to a 2013 research published in the American Journal of Physiology, quercetin has been proven to relax airway muscles and may give relief from asthma symptoms.

The immune system

Dietitian Anne Mauney in Washington, D.C., says onions’ polyphenols serve as antioxidants to protect the body from free radicals. A healthy immune system may be aided by the removal of free radicals. To quote, “unstable molecules” may interfere and destroy the structure of cells in your body, including DNA. Free radicals are these “unstable molecules.” In reaction to pollution, UV light, and our own immune system’s production of free radicals to combat germs and viruses, our bodies manufacture them. Antioxidants, on the other hand, naturally neutralize and restrain them.


An allergy response is triggered when your body releases histamines, which cause you to sneeze, weep, and itch. The University of Maryland Medical Center claims that onions’ quercetin may lessen these symptoms.


Allium vegetables, including onions, have been linked to a lower risk of stomach cancer, according to a study published in the journal Molecular Nutrition & Food Research.

According to Jarzabkowski, quercetin has the potential to be an effective anti-tumor ally. Cancer cells in “breast, colon, prostate, ovarian, endometrial and lung cancers” may be particularly inhibited by quercetin, according to the University of Maryland Medical Center.


Onions have a lot of fiber, which aids with digestion and keeps you regular. Onions also contain oligofructose, a form of soluble fiber that aids in the development of beneficial bacteria in the intestines. In the journal Clinical Gastroenterology and Hepatology, oligofructose has been reported to help prevent and cure various forms of diarrhea. National Onion Association claims that onions’ phytochemicals, which scavenge free radicals, may help lessen the development of stomach ulcers.
