The claim
Consuming alkaline foods can help combat COVID-19 by raising the body's pH levels above those of the virus.
Original review summary
The review says viruses such as SARS-CoV-2 do not have pH values, so the claim’s comparison between body pH and the virus’s purported pH is scientifically meaningless. It also reports that diet cannot alter the body’s tightly regulated blood and cellular pH, and that there is no evidence alkaline foods prevent or treat COVID-19.[S1]
Additional context
The review explains that the listed foods’ claimed pH values are inaccurate; it gives lemon juice as acidic and avocado as near neutral to slightly acidic. [S1]
