According to some recent studies, among the anti-covid foods a set of containing foods are included quercetin, Such as capers, red onion and radicchio. But is it really so or is it yet another fake news sul coronavirus?

Many newspapers reported the news seeing in this substance a sort of “alternative” to the discovery of the vaccine. But the doubts that this is just a hoax remain enormous. As also pointed out by the Food and Drug Administration (FDA).

What is Quercetin

The quercetin (The quercetin The quercetolo) it’s a vegetable pigmentpresent in some plants and various vegetables. Let’s talk about one molecule of natural origin with a bitter taste, as well as a nutritional element with countless beneficial properties for the body.

This substance naturally stimulates the immune system response and helps regulate excessive inflammation. Furthermore, it promotes the biogenesis of mitochondria, strengthens the capillary walls and supports the action of C vitamin.

But that’s not all: quercetin, in fact, is an antioxidant, protects the nervous system, counteracts cellular aging and helps reduce bad cholesterol levels. And according to some scholars inhibits also he SARS Cov-2 thus going, in fact, to diminish the “power” of the gods Covid symptoms.

According to a recent international study published in the journal International journal of biological macromolecules this substance could counter the coronavirus. In fact, the researchers performed a screening on 150 compounds, concluding that quercetin would be able to destabilize the protein (3CLpro) of the virus that affects its development.

But that’s not all: according to experts, in fact, the small size and the particular chemical structure of quercetol would make this substance an ideal basis for developing an optimal synthesis molecule. However, at the moment the work was conducted only in vitro (and therefore this is not a clinical study), although the researchers were optimistic in this regard.

The article published on Aging

In reality, however, the issue is not exactly recent: in fact, in the magazine already last March Aging an article had been published in which professor Michael Lisanti focused on the possible “senolytic” action of foods containing quercetin.

Specifically, in the document the scholar stated how these foods were able to limit skin aging, at the same time representing a new path to recovery against coronavirus. All this, however, without reporting any irrefutable data, nor any scientific evidence.

The position of the Food and Drug Administration (Fda)

The Food and Drug Administration (FDA) – or the US government body that deals with the regulation of food and pharmaceutical products – has warned some companies to promote supplements and foods with quercetin how anti Covi-19 products were possible.

And he did it using strong words: “Based on our review and tests – in fact, we read an FDA document published online – we believe these products are new, unapproved drugs. And therefore sold in violation of section 505 (a) of the Federal Food, Drug, and Cosmetic Act (FD&C Act), 21 USC § 355 (a)”.

In light of all this, therefore, the government agency has the marketing of such anti-coronavirus remedies is prohibited. Stressing that to date “there is no concrete, tangible and scientific evidence that foods containing quercetin can in fact fight the virus”.
