A healthy lifestyle with a balanced diet protects against diseases.
Researchers have now found out which foods are specifically effective against Covid.
The DASH diet * has a positive effect on heart disease and certain foods have also proven themselves with regard to lung diseases.
For example, red grapes, apples and nuts contain many antioxidants such as polyphenols, which have a positive effect on the lungs: "We know that fruits that are rich in polyphenols - such as red grapes - not only cause disease-related inflammatory processes Blood vessels, but also in the lungs ”, says Professor Dieter Köhler from the scientific advisory board of the German Society for Pneumology and Respiratory Medicine (DGP) *.
North Carolina State University researchers looked at what foods can inhibit the coronavirus.
Scientists around the world are concerned with how to treat Covid-19 in a targeted manner.
New drugs and vaccinations are being developed to contain the corona pandemic.
But are there also natural ways to treat corona and prevent a serious course of the disease?
Researchers working with Yue Zuh and De-Yu Xie from North Carolina State University in the United States looked at this question.
They looked at which foods could prevent or slow the spread of coronavirus.
In fact, a number of foods have been shown to inhibit the Sars-CoV-2 pathogen.
The foods examined were
green tea, cocoa powder, muscadine grapes, and dark chocolate
.
The chemical compounds contained and their effect on the proteases of the coronavirus were of particular interest to the US researchers, as reported by ZDF.

Dark chocolate, grapes and green tea against corona?
In particular, the chemical compounds in green tea and muscadine grapes had a complete inhibitory effect on coronaviruses, according to the study.
Dark chocolate and cocoa, on the other hand, were not quite as effective, but had reduced the activity of the protease enzymes by half and thus inhibited the spread of coronaviruses in the test tube.
And this is exactly where the problem lies:
Whether dark chocolate and green tea also have a coronavirus-inhibiting effect in the body of humans or animals has not yet been investigated.
"There are many natural or chemical substances that can inhibit viruses in the test tube," said Professor Friedemann Weber from the Institute for Virology at the Justus Liebig University in Giessen from ZDF.
But that does not mean that these can be transferred to real conditions.
Another factor speaks against a corona-inhibiting diet with chocolate
, grapes and green tea: the food reaches the digestive tract via the mouth, so there is little chance of coming into contact with coronaviruses.
Although the components of the food get into the bloodstream, according to Weber, hardly any effective concentrations can be reached from there.
