Study Links Tellurium Exposure from Diet to High Blood Pressure Risk

A Nagoya University study reveals that tellurium, a pollutant from industrial activities, found in foods like cereals and legumes, may contribute to high blood pressure. Monitoring tellurium levels in foods could help mitigate hypertension risks globally.

Researchers from Nagoya University in Japan have found that higher amounts of tellurium, a pollutant transported from mining and manufacturing, present in certain foods can increase the risk of high blood pressure (hypertension). The findings emphasize the need for improved monitoring of tellurium levels in meals to help reduce hypertension in the general population. According to researcher Takumi Kagawa, the study indicates that tellurium exposure through diet is a significant public health concern.

The study, published in the journal Environment International, explored the dietary habits of Japanese adults and their correlation with hypertension. Foods like rice and natto, which are staple parts of the Japanese diet, were analyzed for tellurium content. Despite these foods being nutrient-rich, they may also contain tellurium due to environmental contamination from industrial activities.

Lead researcher Tomoko Misawa explained that the study involved administering tellurium to mice in amounts comparable to daily human exposure. The results showed increased blood pressure, which normalized after ceasing exposure. This finding supports the link between tellurium and hypertension observed in human participants. The study stresses the importance of continuous monitoring of tellurium levels in foods to mitigate the potential public health risks associated with hypertension worldwide.
