Improve the ratio between potassium and sodium. Americans tend to have
a high sodium diet which changes the ratio. In the book "The K-Factor", by

1986, ISBN 0-02-586190-5.) it makes a very persuasive case that most cases
of hypertension can be controlled nicely merely by getting your potassium
intake up to about 4 times your sodium intake.
