Diets high in nitrates put one at a higher risk for experiencing a manic episode, according to new research. This was found for both subjects that had and did not have past psychiatric issues.

Three types of meat were found to significantly increase the odds of having a manic episode. The dry cured meat was implicated such as meat sticks and beef and turkey jerky. Eating cured meats prepared through dehydration, such as prosciutto and salami, were not associated with mania. Also observed was that undercooked fish or meat did not increase the risk of mania.

This is worth noting especially for those with psychiatric problems.
