In the 1980s it was proven that Taurine (an amino acid) decreased blood pressure and stroke mortality in stroke-prone spontaneously hypertensive rats. Later, the WHO-coordinated Cardiac Study demonstrated that among 5 dietary factors; namely total cholesterol, body mass index, sodium, magnesium, and the Taurine to creatinine ratio in 24-hour urine, both the Taurine to creatinine ratio and magnesium to creatinine ratio were inversely related to coronary heart disease deaths in both men and women and the Taurine to creatinine ratio was inversely related to stroke deaths in both men and women. The ratio means that protected people consumed more magnesium and Taurine in their diets and this was observed through a higher level excreted in the urine and the higher level was strongly linked to not dying from a stroke or heart attack or other related event.
To further analyze the data the researchers from the WHO-Cardiac Study reanalyzed data on members of 61 different population groups from 25 countries excluding those with insufficient data or who consumed a lot of fish (fish is loaded with Taurine). Data from 3960 individuals from 41 populations was used in the final analysis. Those who obviously consumed more magnesium or Taurine than the average person had a significantly lower percentage of body fat (a lower BMI), significantly lower blood pressure, significantly lower cholesterol, and significantly less damage to their arteries. The study is published in the August 24th, 2010 issue of the Journal of Biomedical Science.
