Beef jerky and other processed meats associated with manic episodes -- ScienceDailyA study of their records between 2007 and 2017 showed that, unexpectedly, among people who had been hospitalized for mania, a history of eating cured meat before hospitalization were approximately 3.5 times higher than the group of people without a psychiatric disorder. Cured meats were not associated with a diagnosis of schizoaffective disorder, bipolar disorder in people not hospitalized for mania or in major depressive disorder. No other foods about which participants were queried had a significant association with any of the disorders, or with mania. "We looked at a number of different dietary exposures and cured meat really stood out," says Yolken. "It wasn't just that people with mania have an abnormal diet."
