Health Benefits Of Onions That Are Sure To Impress

1. Can Help With Thyroid Health

Onions, especially the red ones, contain phosphoric acid that is of great benefit to the thyroid gland. One known folk remedy is to rub the juices of a raw red onion all over the neck to stimulate the thyroid gland into producing the right amount of hormones.

Natural compounds in red onions such as antioxidants slow down premature aging and lower blood pressure, which puts less stress on the thyroid gland.

One of the foremost health benefits of onions is their high antioxidant content. This slows down the oxidation process, a reaction that damages cells and causes long-term diseases like diabetes and cancer.

Onions contain over 25 different varieties of antioxidants and flavonoids. These include anthocyanins, which are particular to red onions and are responsible for giving them their deep, vibrant color.

Multiple studies have shown that people who have a diet rich in anthocyanins have a greatly reduced risk of developing heart diseases.

Onions are good for heart health.

The antioxidants in onions not only help combat inflammation. They also help lower cholesterol levels and triglycerides, which leads to lowering the risk of heart disease.

The anti-inflammatory health benefits of onions also help with the reduction of high blood pressure and dangerous blood clots.

Studies show that ingesting quercetin-rich onion extract reduced the blood pressure of 70 overweight patients.

Another study conducted on 54 women saw a huge reduction of LDL cholesterol upon consuming large amounts of raw, red onions.

What Is Quercetin? It is a plant pigment present in foods such as red wine, red onions, berries, apples, as well as green and buckwheat tea. It has antioxidant properties that fight free radicals, reduce inflammation, and lower high blood pressure.

4. Are Full Of Beneficial Nutrients

Onions are dense in nutrients, but quite low in calories, making them a healthy ingredient in any diet. A medium-sized onion has a measly 44 calories but packs quite a punch of fiber, vitamins, and minerals.

Onion benefits include a high vitamin C content, which helps regulate the immune system, boosts the production of collagen, repairs tissues, and helps the body to absorb iron.

Expect a hearty dosage of B vitamins when eating onions as well, including the folate B9 and B6 (pyridoxine). B vitamins are crucial in metabolism, the production of red blood cells, and nerve function.

Potassium is also a surprising mineral found in onions. It is an important ingredient in the body’s task of balancing bodily fluids, transmitting nerves, helping kidneys function, and contracting muscles.

5. Can Help Prevent Cancer

Vegetables in the genus Allium (of which garlic and onion are the most popular), have links to decreased risks of stomach and colorectal cancers. Studies show that those who consumed the most allium vegetables had a 22% lower chance of being diagnosed with stomach cancer.

These potent cancer-fighting properties are linked to sulfur compounds present in onions and garlic, as well as their high flavonoid antioxidant content.

Onions are full of onionin A, which is a compound that contains sulfur and has been known to slow down tumor development, as well as the spread of lung and ovarian cancer.

A study shows that consuming 3.5 ounces of fresh red onions brought down blood sugar levels in just under four hours. This is because quercetin and sulfur compounds found specifically in onions have anti-diabetic properties.

Quercetin has even been shown to control blood sugar by interacting with cells in the liver, pancreas, small intestine, fat tissue, and skeletal muscle.

7. Help Fight Infection

Another of the helpful health benefits of onion is its potent antibacterial properties. They can help fight off E. coli, S. aureus, and Vibrio cholerae.

The compound quercetin has been shown to inflict damage to the cell walls of E. coli and S. aureus. Quercetin that has been extracted from the skin of yellow onions also inhibit the growth of H. pylori and MRSA.

What Is MRSA? Also known as Methicillin-Resistant Staphylococcus Aureus, this bacterium is difficult to treat as it is resistant to common antibiotics.

What Is H. Pylori? Short for Helicobacter Pylori, this type of bacteria can enter your body to live in your digestive tract. It can cause ulcers and sores in your stomach and upper small intestine lining over time.

8. Can Help Boost Digestive Health

Red onion benefits include their being rich in prebiotics and fiber, two ingredients that are crucial for a healthy digestive system.

The way it works is that prebiotics — fiber that is nondigestible — is processed and broken down by good gut bacteria. They, then, form short-chain fatty acids that help keep your gut strong, strengthen immunity, and lower inflammation.

Onions, in particular, are full of inulin and fructooligosaccharides. They are prebiotics that assists in increasing the population of good bacteria in the gut to improve immune function.
