Healthy pH is 6.0-7.5.  Do you know where you are on the scale?  If you don’t know what it is, you need to.

Test Your Body's Acidity or Alkalinity with pH Strips
It is recommended that you test your pH levels to determine if your body's pH needs immediate attention. By using pH test strips (Litmus Paper), you can determine your pH factor quickly and easily in the privacy of your own home. The best time to test your pH is about one hour before a meal and two hours after a meal.

Foods: are they Acid or Alkaline-forming?
Note that a food's acid or alkaline-forming tendency in the body has nothing to do with the actual pH of the food itself. For example, lemons are very acidic, however the end-products they produce after digestion and assimilation are very alkaline so lemons are alkaline-forming in the body. Likewise, meat will test alkaline before digestion but it leaves acidic residue in the body so, like nearly all animal products, meat is classified as acid-forming. It is important that your daily dietary intake of food naturally acts to balance your body pH. To maintain health, the diet should consist of at least 60% alkaline forming foods and at most 40% acid forming foods. To restore health, the diet should consist of 80% alkaline forming foods and 20% acid forming foods.
