An onion a day keeps the doctor away. Well maybe not, but it surely has some amazing benefits for your body which include, supporting your immune system, preventing cancer, detoxifying the body, aiding antioxidant production, supporting healthy digestion, managing anemia, managing diabetes, supporting hair growth, slowing down the aging process, fighting fungal and microbial, relieving pain, relieving cough and cold symptoms, and supporting healthy bones.

Here are some of the extraordinary health benefits of onions

Heart health promotion

According to research, onions can lower blood pressure, which in turn, lowers heart attack risk. The sulfur found in onions is what gives them their characteristic repugnant odor. But this chemical also acts as a natural blood thinner, the same way aspirin does. Also, onions contain quercetin, a molecule, which acts as an anti-inflammatory and helps prevent plaque buildup in the arteries, which reduces the risk of stroke and heart attack.

Anti-inflammatory capabilities

Onions contain both sulfurs and quercetin, in high quantities. These compounds both help reduce inflammation inside the body. Quercetin is especially effective at this, as it’s been shown to relax the airway muscles and provide relief of asthma symptoms. Quercetin also helps fight off other inflammatory states such as infections, colds or other ailments, which brings us to our next point:

Immune system modulation

Onions contain substances known as polyphenols which act as antioxidants, protecting the body from free radicals. These free radicals are what wear down the body in time and can grind down your immune system. They also wear out other cells, causing premature aging and even cell death. So, it’s in our best interest to eliminate as many free radicals as possible from our bodies, and onions can be of great help.

Cancer prevention

A substance found inside onions and garlic, called allium, has been shown to greatly reduce gastric cancer risk. This compound also plays a role in preventing colorectal, laryngeal, oral, esophageal and ovarian cancer as well.

As stated before, onions also contain a great deal of quercetin, a compound which has amazing anti-inflammatory properties. Constant inflammation is cancer-promoting, so one would definitely want to reduce it as much as possible.

Digestion Aid

Onions are also high in fiber, which greatly aids in healthy digestion. It can also promote the growth of healthy bacteria within your intestines, due to a prebiotic. This compound is a soluble fiber that aids in the development of your gut flora. Your intestinal biome is responsible for almost everything happening within your body, from immune system functionality to absorption of nutrients from foods, production of hormones and neurotransmitters and much, much more.

Blood sugar regulation

Onion’s blood sugar lowering capabilities are twofold. For starters, they are high in chromium. This mineral helps in lowering blood sugar. The sulfur in onions also works in this area, by stimulating insulin production. This is of great help to people suffering from Type 1 or Type 2 diabetes. Blood sugar regulation is also important for healthy people as well. Our modern diets are riddled with low-quality carbohydrates which are taxing our bodies to constantly pump insulin to manage the spikes in blood sugar. Keeping glycemia low, is not only optimal for health but also prevents many other diseases such as Alzheimer’s, heart disease and cancer.
