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
