Beef jerky and processed meats linked to manic episodes

Beef jerky and processed meats linked to manic episodes

Eating a lot of hot dogs, beef jerky, salami and other processed meats could do more than just add a few extra pounds - it could cause a serious mental condition called mania.

Experiments in rats by the researchers from Johns Hopkins University in the USA showed that mania-like hyperactivity after just a few weeks on diets with added nitrates. They asked the same questions of people who did not have any psychiatric disorders. Researchers, hence, are looking at diet as a plausible causative factor among other things.

Prof Robert Yolken added: 'Future work on this association could lead to dietary interventions to help reduce the risk of manic episodes'.

The human study wasn't powered to investigate cause-and-effect, so the team next investigated the potential effects of nitrate-cured meats on the behaviors of healthy rats.

Director of National Intelligence Dan Coats told a security conference he's sure the ball "has been looked at very carefully". Coats also said he had no idea what the two leaders spoke about, and said he woudl not have set it up the way it happened.

The survey did not take into account the time frame of cured meat consumption hence the researchers could not infer exactly how much cured meat triggers an individual's risk of mania.

Nitrates have always been used as preservatives in cured meat products and have been previously linked to some cancers and neurodegenerative diseases.

When the researchers looked back on a decade of responses to the questionnaires, between 2007 and 2017, they noticed that patients with bipolar mania turned out to answer "yes" to that question far more often than patients with other disorders (such as bipolar depression or schizophrenia) or people who had not been diagnosed with psychiatric disorders.

For the first study, the researchers didn't even intend to look at cured meats, said study co-author Faith Dickerson, director of the Stanley Research Program at Sheppard Pratt Health System.

Next, the team worked with a Baltimore beef jerky company to create a special nitrate-free dried beef. In the study, some people without a history of psychiatric disorders also consumed meats with nitrates. They repeated the experiment, this time giving some rats the store-bought, nitrate-prepared jerky and others the nitrate-free formulation. Certain kinds of cured meats, including beef or turkey jerky and meat sticks, were linked to the highest risk for mania, while those consuming prosciutto and dehydrated cured meats did not show a significant increased risk of mania. Diet has been highlighted as a potentially key environmental factor that may contribute to the risk of BPD and other neuropsychiatric disorder risks, through a variety of mechanisms that may range from neurotoxicity from trace heavy metals, to changes to the gut microbiome and gut-brain axis. They found that rats with nitrate in their diet had different patterns of bacteria living in their intestines than the other rats.

"In patients at risk for manic episodes, it is possible that dietary exposures interact with existing genetic vulnerabilities and other environmental and social risk factors in the emergence and severity of the illness", the Hopkins researchers said.
