The study, published Wednesday in Molecular Psychiatry, found that the nitrates present in processed and cured meats like hot dogs, salami. bacon and beef jerky may contribute to mania, a high-energy mood state that can manifest as part of bipolar disorder or, more rarely, schizoaffective disorder.

In order to qualify as a manic episode, a mood disruption must last a week or more and go along with some combination of decreased need for sleep, inflated grandiosity, a surge in talkativeness, racing thoughts, heightened distractibility and agitation, and excessive involvement in risky pleasure-seeking activities like sex and spending money, according to the Diagnostic and Statistical Manual of Mental Disorders.
