How to change the pH of the body?

I have heard that your body should be alkiline (pH over 7), and you can test your bodies pH using those paper tabs from the health food stores. How would a person change their pH? i don't know what foods, etc would cause a change.How to change the pH of the body?
When I had a high acidity level due to taking medicine and drinking too much coffee and pop, I found that drinking a lot of water and herbal tea helped to clear up the problem very quickly and easily.



The link below shows which foods have acid or alkaline forming foods, eating a balance from each list should help keep the body's ph balanced. Many times the body's ph will become very acidic when a lot of caffeine drinks, meat and medicine are being takenHow to change the pH of the body?
I am not sure what you mean by ';your body'; should be alkaline, but your blood's pH already IS naturally slightly alkaline at 7.4 (average range 7.35 to 7.45). Why would you want to change it? Since your blood is highly buffered, it would take large amounts of acid or base to offset your blood's pH. However, once those buffers are overcome, even small amounts of acid or base could change your blood pH (you may have had these sorts of experiments in your chemistry class). Once you reach this stage, you could be in serious trouble.



If your pH is even slightly off balance (less than 7.2 or greater than 7.6), you could be in severe distress where you are hyperventilating, put on a respirator and certainly in the ICU.



Presence of either acidosis or alkalosis usually means there is something that is utterly wrong, whether it be your kidneys, lungs, your blood sugar, extreme dehydration or any of numerous other causes.
Avoid excessive protein and fats because your body will need to buffer the acids (amino and fatty) by pulling minerals from your bones. Sugar and grains are also acidic. So, what can you eat?

Lean meats like chicken and turkey breast with lots of green leafy veggies and citrus fruits, berries. In fact most low glycemic fruits and veggies are great. Just avoid the starchy vegetables and high glycemic melons and your PH should be fine.
