Hotdogs and other cured meat such as salami and beef jerky may be causing manic episodes, according to a new study.
Scientists say they suspect the chemical preservative nitrate is causing the disorders.
They found people hospitalised for an episode had more than three times the odds of having ever eaten nitrate-cured meats than people without a history of a serious psychiatric condition.
The study was backed up a further experiment in rats who were fed a diet with added nitrates and had mania-like hyperactivity after just a few weeks.
Well, I would be, if they then fed people leafy veg (spinach, arugula) and then found the same effect.
But the larger idea, that there might be harmful effects? Sure, why not? For as with so many things we’ not be surprised to find more than one thing going on.
Those who, historically, ate such cured meats would not be deaded through starvation. The minor effect of mania would be swamped by that carrying on living thing.
