A range of foods and drinks, including dark chocolate, green tea and muscadine grapes, could be a secret weapon in the fight against Covid-19. New research has found that they contain compounds that can kill the virus.
Scientists studied what happened when the virus responsible for Covid-19 – SARS-CoV-2 – collided with chemical compounds found in plants known for their anti-inflammatory and antioxidant properties.
In a fascinating way, they discovered that the compounds in green tea, two varieties of muscadine grapes, cocoa powder and dark chocolate were able to bind to a particular enzyme, or protease, in the virus and prevent it. to reproduce.

The researchers, at North Carolina State University, conducted laboratory studies and computer simulations to examine how the so-called main protease (Mpro) of the coronavirus reacted to plant compounds.
“Mpro in SARS-CoV-2 is necessary for the virus to replicate and assemble. If we can inhibit or deactivate this protease, the virus will die ” Corresponding study author DeYu Xie explained.
Investigations have found that chemical compounds found in food and drink fill a “pocket” in Mpro, rendering it useless, effectively preventing the virus from replicating.
“Green tea has five tested chemical compounds that bind to different sites in the Mpro pouch, essentially overwhelming it to inhibit its function,” Xie said.
“Muscadine grapes contain these inhibitory chemicals in their skins and seeds. Plants use these compounds to protect themselves, so it’s no surprise that the leaves and skins of plants contain these beneficial compounds.
