Eating alot of fresh fruit is a good place to start. Drink water like the Water Cure says to.
Cut down on acid forming foods like meat and potatoes.
Get some pH tape from a health food store. Keep checking your urine and try to take in enough alkaline foods every day to keep the reading at 7 or above.
After awhile your saliva should get up to about 6.4
The longer you do this, the more stored acids your body will release. And your body will replace alkaline minerals to your bones and tissues.
