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 used to preserve food, sodium nitrite, has been linked to a surge in suicide deaths among young people in the UK, according to a recent study. Researchers analyzed 201 suspected cases of poisoning from 2019 to 2024, finding that the majority of victims were under the age of 30, with young men comprising the largest group.
The average age of those affected was 28, with 71% of cases involving individuals aged 17-82. Blood tests revealed nitrite and nitrate levels 100 times higher than normal, suggesting deliberate ingestion. The study, published in BMJ Public Health, emphasizes the need to regulate access to the chemical and curb the spread of harmful online information.
Lead researcher Professor Amrita Ahluwalia expressed the distressing nature of the findings and the urgent need for regulation to prevent further avoidable deaths.
