This is said to be the first study of its kind to link blood pressure to a persons "metabolic fingerprint". That's a measure of how they process food.
The international study by Imperial College London found chemicals called metabolites in people's urine. These they say have a direct relation to blood pressure, linking it to diets rich in meat, high in alcohol and low in fiber. They say metabolic profiling could point the way to greater understanding of dietary and biological causes of the epidemic of high blood pressure.
