Overview

  • Tomato juice has been found to kill Salmonella Typhi and other bacteria that can harm people's digestive and urinary tract health, according to research published in Microbiology Spectrum.
  • The researchers identified two antimicrobial peptides in tomatoes that impair the bacterial membrane, effectively killing the bacteria.
  • The study also found that tomato juice is effective against hypervirulent variants of Salmonella Typhi and other harmful bacteria.
  • The researchers hope that the findings will encourage increased consumption of tomatoes and other fruits and vegetables for their natural antibacterial benefits.
  • The findings suggest a promising new avenue for antimicrobial therapy, particularly in the face of global antibiotic resistance.
