Trehalose, a sugar additive used in processed foods, has been linked to the rise of more virulent strains of *Clostridioides difficile* (C. diff), a bacterium that causes colitis, an inflammation of the colon. Studies suggest that certain strains of *C. diff*, particularly those causing severe infections, can metabolize low concentrations of trehalose more efficiently, giving them a survival advantage in the gut. This can lead to increased toxin production, worsening colitis symptoms like severe
