evidence: A claim posted on Facebook alleged that the pH of the coronavirus varies from 5.5 to 8.5, and "all we need to do, to beat coronavirus," is eat alkaline foods above the pH levels of the virus. The pH of the coronavirus [...] The claim that an alkaline diet will help beat the coronavirus is FALSE. The claim that coronavirus has a pH level of 5.5 to 8.5 cited a study from 1991 about a different coronavirus, not the one that causes COVID-19. The post misinterpreted the findings of that study. The idea that alkaline foods will help beat the coronavirus is also false. There are no confirmed preventive measures or cures for COVID-19. Though a healthy diet can help strengthen immune systems, there is not enough of an effect to stop the coronavirus.
