Quercetin: A Flavonoid in Onions

Onions are a staple in my kitchen. If I am frying a portion of salmon. I like to have sauteed onions in the pan. Onions add flavor to almost every kind of meat. I place onions in the cavity of a chicken or a turkey before roasting. I have a nice recipe for a skillet cornbread with onions.

The Bible mentions onions also. The children of Israel recalled the food they had enjoyed in Egypt and missed as they traveled through the wilderness.

We remember the fish we ate in Egypt that cost nothing, the cucumbers, the melons, the leeks, the onions and the garlic. Numbers 11:5

What is the nutritional value of an onion? According to my Nutrition Almanac cooked, mature onions are a source of minerals (calcium, phosphorus, potassium) and a little vitamin A and C.

They also contain a flavonoid, quercetin, that has been discussed in relation to covid-19.

Molly Knudsen, MS, RDN wrote an article titled, What Makes Onions So Healthy? It’s Quercetin. Click here to read about the health benefits of onions and quercetin.

I have read that quercetin assists the absorption of zinc into cells, assisting the immune system to fight off viral infections. 

An article on web MD lists six foods that contain quercetin. I was happy to see apples and blueberries on the list.

Although the practice of medicine offers many treatments for disease, I believe my role as wife and mother is to encourage diet and nutrition that supports the immune system. God has designed our body with an intricate immune system and has given us resources in fruits and vegetables. 

My husband and I are in the age bracket more susceptible to covid-19. We are taking vitamin supplements in addition to having a healthy diet. 

A large percentage of people in the United States have an inadequate level of vitamin D. A few years ago, my doctor noticed that my vitamin D level was low (insufficiency) and prescribed a supplement. Since then, I have continued to take a vitamin D supplement. 

A blood level of 30 to 100 ng/mL is considered sufficient. Greater than 100 ng/mL is toxic. Over the past three years I have been able to bring my blood level up to 49 ng/mL and have noticed improved health of my mouth/gums. I have less bleeding gums and improved dental appointments.

Some studies have shown that people with a good blood level of vitamin D are more likely to recover from a covid-19 infection.
