Common food preservative linked to rising suicide deaths among young people
A widely available food-preservation chemical is emerging as a disturbing factor in rising UK suicide deaths, particularly among younger people and men. Researchers say the scale may be underestimated and are calling for urgent restrictions on access and harmful online information.
A chemical widely used to preserve food may be linked to a surge in suicide deaths among young people in the UK, according to a new study. The findings, published in the open-access journal BMJ Public Health, show that the increase in suicide cases is particularly concerning among younger generations, with nearly three-quarters of cases involving individuals aged 14-74.
Men accounted for the majority of cases, with over half of the total. Blood tests revealed that concentrations of nitrite and nitrate were 100 times higher than normal, suggesting intentional use of the chemical. Researchers caution that the actual incidence of sodium nitrite-related suicides may be underreported, as the chemical is not routinely tested in suicides.
They also highlight the role of online information in promoting its use, particularly among younger people with greater digital literacy. The study calls for urgent action to restrict access to sodium nitrite and to address the dissemination of harmful information online.
