What Is Quercetin?
Quercetin is a type of flavonoid antioxidant that’s found in plant foods, including leafy greens, tomatoes, berries and broccoli.
Considered one of the most abundant antioxidants in the human diet, quercetin plays an important part in fighting free radical damage, the effects of aging and inflammation. While you can get plenty of quercetin from eating a healthy diet, some people also take quercetin supplements for their strong anti-inflammatory effects.
According to the Department of Pathology and Diagnostics at the University of Verona in Italy, quercetin and other flavonoids are "anti-viral, anti-microbial, anti-inflammatory and anti-allergic agents” with potential to be expressed positively in different cell types in both animals and humans. Flavonoid polyphenols are most beneficial for down-regulating or suppressing inflammatory pathways and functions. Quercetin is considered the most diffused and known nature-derived flavonol there is, showing strong effects on immunity and inflammation caused by leukocytes and other intracellular signals.
How Does Quercetin Work and How Much Do We Need?
Research shows that anti-inflammatory foods containing quercetin can help manage a number of inflammatory health problems, including heart disease and blood vessel problems, allergies, infections, chronic fatigue, and symptoms related to autoimmune disorders like arthritis. How exactly do flavonoids like quercetin do so much to benefit us?
It all comes down to high-antioxidant foods‘ ability to be "scavenge free radicals.” As a major bioflavonoid in our diets, quercetin (a type of "polyphenolic antioxidant”) helps slow the aging progress because it lessens the effects of oxidative stress on the body. Oxidative stress takes place in all of us but is increased by things like a poor diet, high levels of stress, a lack of sleep and exposure to chemical toxins.
Quercetin plays a role in regulating the immune system’s response to outside stressors through cell signaling pathways called kinases and phosphatases, two types of enzyme and membrane proteins needed for proper cellular function.
Quercetin helps Fights Allergies
Quercetin is a natural antihistamine and an anti-inflammatory, making it effective for naturally lowering the effects of season and food allergies, plus asthma and skin reactions. Histamines are chemicals that are released when the immune system detects an allergy or sensitivity, and they are what account for uncomfortable symptoms we face whenever the body has an allergic reaction.
Quercetin can help stabilize the release of histamines from certain immune cells, which results in decreased symptoms like coughs, watery eyes, runny noses, hives, swollen lips or tongue, and indigestion. In fact, it’s so effective that quercetin is used in ancient Chinese herbal formulas created to block allergies to certain foods (such as peanuts), known as food allergy herbal formulas. Studies show that quercetin, a natural medicine and phytochemical, is equivalent at fighting allergies as some prescription medications, all with little to no side effects.
