Processed Meats Found to Increase Chance of Manic Episodes

     A new study out of Johns Hopkins Medicine found that nitrates found in processed meats may contribute to manic episodes. Those that eat foods with nitrates in them are 3 times more likely to experience mania. Furthermore, research also found that the amount and type of bacteria in the gut may also affect the brain. These findings were replicated in rats. It would be interesting to see numbers behind the study like the amount of nitrates that need to be ingested before it has adverse health effects. Just as most foods are now trans-fat free or low; deli meats might make the switch to zero nitrates.
