Onions are a staple in many kitchens.
They add flavor to food, but what happens when you eat them every day?
This article will discuss the benefit and effects of eating onions and show you how they can help fight diseases.
Read on to learn more about what happens to your body when you eat onions every day.
1. You’ll get plenty of nutrients
Onions are a nutrient-dense food, providing a rich source of vitamin C, chromium, potassium, manganese, and fiber.
Vitamin C is an antioxidant that helps with cell growth, while chromium regulates insulin levels in the blood to prevent diabetes.
Potassium works together with sodium ions in cells to maintain proper fluid balance inside and outside of cells throughout your body.
Manganese acts as a cofactor for several enzymes, and it’s needed to form connective tissue.
Fiber helps prevent constipation, hemorrhoids, and even certain types of cancer.
Onions also provide a good source of vitamin B complex, especially folate, which is needed in the synthesis of DNA.
Folate helps lower your risk for heart disease and birth defects when consumed before pregnancy.
What’s more, onions are an excellent source of flavonoid antioxidants.
In fact, red onions, in particular, contain anthocyanins that offer potent antioxidant, and anti-inflammatory benefits.
Allicin is also an important nutrient found only in onions that helps protect the body from disease and infection.
Lastly, onions contain calcium, iron, and phosphorus.
Calcium is needed for bone mineralization, while iron helps make red blood cells transport oxygen throughout the body.
Phosphorus works together with calcium to help support strong teeth and bones too!
Bottom line: Onions are jam-packed with vitamins, minerals, and antioxidants that support good health.
Now that you know what nutrients onions provide for your body let’s look at what really happens if you eat onions every day.
2. Onions may boost your mood and reduce depressive symptoms
Eating foods high in chromium, like onions, may stabilize mood and help prevent depression.
The vitamin B complex found in onions also supports good mental health by preventing brain fog or fatigue, while folate prevents depression by creating new brain cells.
So eating onions every day may help keep you mentally healthy and less likely to get depressed!
3. If you have high blood pressure, onions may help lower it.
Onions contain a flavonoid antioxidant called quercetin, which has been shown to reduce blood pressure in people with hypertension.

In short, onions are effective at reducing high blood pressure when consumed raw or lightly cooked.

What happens to your body when you eat onions every day is that it may help maintain healthy blood sugar levels.
The quercetin in onions helps regulate insulin levels since it interferes with the enzymes that break carbohydrates down into simple sugars.

A study showed that people with type 2 diabetes who ate fresh red onion had their fasting blood sugar levels go down by about 40 mg/dl after four hours.
6 Onions may lower your risk of cancer
Eating onions daily can also protect against different types of cancers.
The sulfur-containing compound found in onions may help prevent cancer growth, especially colon and stomach cancers.

This means it can help prevent cancer by removing free radicals from your body’s cells while stopping the growth of some types of cancers.
7. Onions will Improve gut health
Onions may also improve gut health by stimulating the growth of healthy bacteria in your intestines.
This can help fight against intestinal infections and digestive issues.
In addition, onions enhance the production of bile to break down fats which aid digestion.
8. Onions may help promote healthy skin
Onions are a rich source of vitamin C, a nutrient that helps produce collagen in the skin.
Collagen is important for keeping your skin healthy and preventing wrinkles.
Also, onions contain antioxidant and anti-inflammatory properties, which can help reduce skin damage caused by free radicals in the environment.
This can result in a reduction of fine lines and wrinkles.

Onions contain powerful antioxidants called polyphenols that help protect the lungs against oxidative damage and free radical formation.
Free radicals can cause or worsen respiratory conditions like asthma, emphysema, and chronic obstructive pulmonary disease (COPD).
So eating onions every day could reduce your risk of lung diseases.
10. Onion may help improve your memory and reduce dementia risk.
Onions contain an organosulfur compound called S-Allycysteine, which is used by the body to produce acetylcholine.
This neurotransmitter plays an important role in memory and learning, as well as cognitive function.
Also, onions have been shown to help reduce the risk of dementia and Alzheimer’s disease due to their anti-inflammatory and antioxidant properties.
As a result, onions could be very beneficial for your brain health!
11. Onions may increase gas and bloat for some people
Eating onions every day could also cause gas and bloating in some people, especially those with Irritable Bowel Syndrome.

12. You may experience heartburn if you eat a lot of onions
Eating too many onions may also trigger acid reflux or heartburn because they contain a high amount of FODMAPs.
FODMAPs are a type of carbohydrate that can cause digestive issues for some people.
People who experience heartburn when eating onions should reduce the amount they consume in their diets to avoid further problems with intestinal discomfort.

Eating fresh onion daily can provide many health benefits.
They may reduce your risk for cancer, improve gut health and skin condition, promote heart health, and increase memory function, among other things.
