ONION OVERVIEW INFORMATION

Onion is a plant. The bulb (rounded underground part) of the onion is used to make medicine.

Onion is used for treating digestion problems including loss of appetite, upset stomach, and gallbladder disorders; for treating heart and blood vessel problems including chest pain (angina) and high blood pressure; and for preventing “hardening of the arteries” (atherosclerosis). It is also used for treating sore mouth and throat, whooping cough, bronchitis, asthma, dehydration, intestinal gas, parasitic worms, and diabetes. Some people use it as a diuretic to increase urine output.

Onion is applied directly to the skin for insect bites, wounds, light burns, boils, warts, and bruises.

In foods, onion is used in many recipes.

In manufacturing, the oil is used to flavor foods.

How does it work?

Onion might help reduce cholesterol levels, a risk factor for hardening of the arteries. There is some evidence that onion might also reduce lung tightness in people with asthma.

Surprisingly, onion demonstrates significant enough blood sugar-modifying properties to be a real help in the fight against both type 2 diabetes and obesity. No, onion alone won’t keep you in fine shape, but it will help greatly. In addition to limiting your intake of fats and sugars, eating onion can get your blood sugar- and your weight- on the right track.

So here is a simple, powerful health-enhancing recommendation. Eat an onion every day. One medium-sized onion equals approximately one cup of onion when chopped. And while raw onions contain a whopping load of protective compounds, even when cooked onions still weigh in very heavily on the protective side.
1. Asthma

Onions have antihistamine effects due to quercetin, an antioxidant that acts like an antihistamine and an anti-inflammatory agent. In test tubes, quercetin has proven toprevent immune cells from releasing histamine, which are chemicals that cause allergic reaction. Based on this observation, researchers believe the antioxidants may reduce histamine, and other allergic or inflammatory chemicals in the body, and can be a promising asthma treatment.

However, no human studies have examined whether it works or not. Stegall believes onions help alleviate asthma because they act as a powerful antioxidant. “Studies have shown that quercetin causes the bronchi of the respiratory tract to widen,” he said.

2. Cancer

Onions can help reduce cancer risk when combined with turmeric. Chemicals found in these two cooking ingredients. A 2006 study published in Clinical Gastroenterology and Hepatology found the combination of onions and turmeric creates a synergistic effect that reduces both the size and number of precancerous hosts in the intestine, therefore reducing colon cancer risk. Moreover, Stegall suggests regularly consuming onions can help detoxify potential carcinogens. Since they contain organosulfur compounds. “These compounds are found in the cell wall of the onion, and are released when the onion is chopped or chewed,

3. Diabetes

A high intake of onions could mean the lower the level of glucose. The essential oil of an onion, allyl propyl disulphide, is found to mediate this effect, and lower blood sugar levels by increasing the amount of free insulin that is available. The allyl propyl disulphide competes with the insulin, which is also a disulphide, to occupy the sites in the liver where the insulin is inactivated. This is what leads to an increase in insulin available, which lowers blood sugar levels. A 1975 study published in the journal Clinica Chimica Acta; International Journal of Clinical Chemistry found onion’s essential oil led to a significant fall in blood glucose levels, and a significant rise in the serum of insulin levels after being administered to six normal volunteers after a 12-hour fast.

4. Heart Disease

When we think of heart healthy food, onions do not come to mind. However, quercetin is found to significantly reduce high blood pressure in hypertensive adults, Moreover, this vegetable is considered to exceed the heart-protective properties of red wine. Stegall shared, “Onions are involved in maintaining good blood pressure, inhibit hardening of the arteries, and keep the arteries elastic.”

5. Tooth Decay

Raw onions may make our breath stink, but they can actually improve our oral health. Simply chewing a raw onion can strengthen teeth and eliminate bacteria that can lead to tooth decay. Two to three minutes of chewing on an onion can kill most germs in the mouth,

To stay healthy and prevent the onset of these diseases, eat an onion a day to keep the doctor away.
