Onions are part of the alluim family, just like garlic, scallions, leeks, and chives. The most familiar allium is the bulb onion, which comes in yellow, white, purple and red skins.

Onions and Antioxidants

Since ancient times, onions have been used in herbal medicine. Recent studies have shown that onion consumption reduces the risk of cardiovascular issues, cancer and reduction of inflammation. In studying the amount of flavonoids and phenols in many varieties of onions, it appears that onions are also high in antioxidants. Quercetin and kaempferol have antibacterial properties, and may even help as a natural food preservative.

Extracts from onions may inhibit the growth of bacteria that is commonly associated with food deterioration.

Flavonoids can reduce the risk of coronary heart disease. Flavonoids are concentrated in the outer most layers of the fleshy part of the onion. Onions also contain queretin, a type of antioxidant that slows the damage oxidation causes to our tissues and our cells. In studies, quercetin has proven to be able to get rid of free radicals in the body. We absorb quercetin twice as much from tea, and three times as much from apples. Onions may be able to prevent gastric ulcers by going after free radicals, by preventing the microorganisms that encourage ulcers to form.

Onions Can Help Fight Disease

Pungent onions have a powerful ability to stop platelet accumulation which is linked to cardiovascular disease and related health problems. At the University of Wisconsin, ongoing studies are being conducted to understand more about the powerful properties of onions. The researchers are looking into the possibility that onions can be used as a blood thinner and platelet inhibitor. Onions may also be able decrease osteoporosis.

Onions add wonderful flavor to food and has many value added health characteristics.

Several studies have shown quercetin to have beneficial effects against many diseases and disorders including cataracts, cardiovascular disease as well as cancer of the breast, colon, ovarian, gastric, lung, and bladder.

In addition to quercetin, onions contain the phytochemicals known as disulfides, trisulfides, cepaene, and vinyl dithiins. These compounds have a variety of health-functional properties, including anticancer and antimicrobial activities.

Quercetin doesn’t degrade, even when onions are simmered in hot water to make soup. The quercetin gets into the water of the soup. Heating onions on a low heat does not take away any of the good health effects of the onion.

The quercitin we get from onions is better than the quercitin we can get from supplements. Studies have shown we get better protection from oxidative stress when we eat an onion, cooked or raw.

Onions, whether boiled, fried, microwaved, baked, or sauteed, retain their levels of quercitin.

Onions Have Many Benefits

It seems that eating about one to seven servings of onions on a weekly basis can effectively lower the risk of some types of cancer, including colorectal, laryngeal, and ovarian. To reduce the risk of esophageal cancer, you would need to eat a serving of onions each day. A serving of an onion is equivalent to about 1/2 cup.

Onions can have a sweet flavor. If you saute onions for 7 minutes, you can savor that sweet flavor.

When you saute onions, it is a great way to bring out the sweet flavor of them. It only takes about 7 minutes. Cut the onions into equal slices about 1/4 inch

so they cook evenly. The thinner the onions are sliced, the faster they cook. After they have cooked, turn the heat off of the stove and let them sit for about five minutes. This helps enhance the healthier qualities of the onions.

Most research on the cardiovascular benefits of onions has been done on animals. Evidence is showing that the sulfur compounds in onions may have anti clotting abilities. This science believes may help prevent the blood platelet cells from clumping together. Sulfur compounds may also lower blood levels of cholesterol and triglycerides and improve cell membrane function in red blood cells.

People who eat onions and other fruits and vegetables that are high in flavonoids may help prevent heart attacks.

Over and over again studies are showing that onions added to meals have many benefits to our overall health in many ways.

The sulfur content of onions also have show to have many benefits to our connective tissue. Connective tissue requires sulfur for its formation.

Onions may also help with rheumatoid arthritis and other inflammatory problems. The anti inflammatory benefits of onions are still be studied.

The bulb portion of the onion contains a unique sulfur molecule that has shown it can help control certain specialized white blood cells that affect our body’s immune defense system and is involved in triggering a large scale inflammatory response that can cause unwanted inflammation.

      Great hub. I love onions and put them in just about everything i cook (except desserts- L.O.L.).

      I suppose they will be the next to be destroyed by GMO people who care more about $$ than health benefits. I have lost the tomato, brocolli, cauliflower, corn,and other favorite foods to the GMO craze in this country (U.S.)

      I can only pray that the side effects of eating GMO foods are minimal, but with the recent studies in France showing them to cause wide spread tumors in lab animals, i am afraid my hopes are for naught.

      We used to eat raw onions like apples when we were kids. I can't imagine any kids doing that today.

      Good info. More people need to know the benefits of sulfur containing foods. The body needs sulfur to make glutathione, which is the body's master antioxidant and detoxifier. Besides onions and garlic, I like to get my sulfur from broccoli, kale, cabbage, aspragus, and brussel sprouts.

      Good information my friend. I just don't like them that much. Bev, on the other hand, loves them, which makes for some interesting kissing. :)

      I'll pass this on to her and you have our thanks.
