Magnesium potassium lowers blood pressure
Report #6320 9/10/94
High blood pressure can shorten your life by causing heart attacks and strokes. 
Several recent reports show that you can lower high blood pressure just by 
changing your intake of the minerals in your diet.

A normal blood pressure is 120 when your heart contracts and 80 when it relaxes. 
If you blood pressure is greater than 140 when your heart contracts or 90 when 
it relaxes, you have high blood pressure. The most effective treatment for high 
blood pressure is to go a low-fat diet and lose weight. Several studies show 
that more than 60% of overweight people with high blood pressure can have their 
blood pressures return to normal when they lose weight. The second most 
effective treatment is to take medications, but a significant number of people 
can control their high blood pressure by reducing their intake of sodium table 
salt and increasing their intake of calcium, potassium and magnesium. A study 
in the July issue of the American Journal of Clinical Nutrition shows that 
increasing your intake of magnesium helps to lower high blood pressure. Another 
study in the August issue of the British Medical journal shows that replacing 
table salt with a special salt containing potassium and magnesium lowered blood 
pressure even more. 

If you have high blood pressure and are overweight, go on a low-fat diet and 
lose weight. Do not add salt to your food or cooking and avoid foods that taste 
salty. Increase your intake of fruits, vegetables, grains and beans because 
they are rich sources of potassium and magnesium and poor sources of sodium
