Although onion consists of almost 90% water, it provides a remarkable variety of nutrients.
Minerals such as potassium, magnesium, and calcium or vitamins B6 and B9 should be emphasized (*).
Furthermore, adequate vitamin C content makes it a food that promotes collagen formation for skin, hair, and bones.
Nevertheless, real onion benefits lie in its bioactive substances, the polyphenols.
1. It’s Packed With Antioxidants
Onions are full of antioxidants. Above all, they stem from various polyphenols. However, the essential flavonoid quercetin is abundant in all onions.
In total, you can find more than 25 different flavonoids in various types of onions. Additionally, red onions contain over 25 anthocyanins.
These antioxidants prevent the oxidation of fatty acids, both in food and cells.
In this function, both quercetin and anthocyanins intercept free radicals, which reduces inflammation in the body and inhibits cancer cells’ development.
Antioxidant polyphenols are found precisely in the outer layers of the onion. Therefore, removing the two outer flesh layers can cost up to ¾ of all anthocyanins and up to ¼ of quercetin.
Nevertheless, experts believe that quercetin from onions is absorbed much better by the body than from dietary supplements.
2. They Strengthen the Immune System
Since the bioactive substances in onions have anti-inflammatory benefits, it is not surprising that they can strengthen the immune system in general.
In addition to reducing free radicals, the active ingredients in onion also develop anti-allergic properties.
These effects occur through the stimulation of the immune system, antiviral activities, reduction of proinflammatory cytokines, or histamine release.
Due to the reduced histamine release, onions can combat sneezing, weeping, and itching in allergic reactions.
Accordingly, a study in the American Journal of Physiology found that quercetin relaxes respiratory muscles and may relieve asthma symptoms.
3. Onion Offers Antibacterial Benefits
That a cheap and abundant food can fight bacteria comes in handy – especially in times of the coronavirus.
Onions can fight various potentially dangerous bacteria such as E. coli or S. aureus.
Onions can also inhibit the growth of pathogens, such as cholera, which is still a significant public health problem in developing countries.
Laboratory experiments show that the flavonoid quercetin is responsible for the onions’ broad antibacterial benefits (Ramos et al. 200610).
Quercetin can damage cell walls and membranes of bacteria.
4. Help Prevent Heart Disease
Both the antioxidant and sulfur compounds in onions counteract blood clotting, which reduces the risk of heart attacks and strokes.
Besides its anti-inflammatory effect, the onion’s ability to lower triglyceride levels reduces heart disease risk in general.
5. Lower Blood Pressure
In a randomized placebo-controlled double-blind trial, researchers determined the antihypertensive effect of quercetin extracted from onions.
In this study, the flavonoid could lower blood pressure, although the subjects were overweight to obese.
Since many people argue that the body better absorbs quercetin from food, real onions could even be more beneficial for hypertension than supplements.
6. Help Regulates Blood Sugar
Specific sulfur compounds, quercetin, and chromium in onions can have antidiabetic effects.
A meta-analysis carried out in 2014 showed that patients with type 2 diabetes had better liver enzymes and lower glycaemic values after eating onions (Akash et al. 201415).
Also, further studies have shown that quercetin interacts with cells of the liver, small intestine, pancreas, muscles, and fatty tissue to regulate blood sugar levels throughout the body.
7. Onion Has Anticancer Benefits
According to a study conducted by the University of Guelph, different onion varieties can contribute to the destruction of breast and colon cancer cells.
