What research says

Studies in people

  • Concern

    Prostate cancer risk3

    In people, eating more sodium nitrite as a food additive was linked to more prostate cancer, though scientists say this needs confirming.

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least two findings in people. Findings whose study type is not stated are shown but not counted.
