This sounds misleading. Sure your body can control acidity/alkalinity in your body, but only to a point. The body works according to the principle of homeostasis - always trying to maintian a balance. Its like saying it doesn't matter if you heat hot stuff or cold stuff since your body's thermostat regulates heat to within a narrow range. *Yes but only to a point*. Try eating snow for an hour - you will quickly get hypothermia and die. Similarly try running in a hot desert without the cooling effect of water - you will get heat exhaustion and die.

The stomach itself is acid because thats how the stomach works to break down and digest food. The intestines themselves are alkaline because again thats how they work to break down food. But the food itself that is entering these regions can be either acid or alkaline.

If we eat something acid forming or alkaline forming it won't make much difference. But over a lifetime if we eat acid forming food or alkaline forming food it will make a huge difference to our body-chemistry. Similarly over several months, even weeks, perhaps even days.

The tricky part about this whole acid/alkaline thing is that it is not so much the acidity/alkalinity of the food itself, but rather the effect it produces on the body. For example lemons are citrous fruit and therefore clearly acidic ( citric acid ). But eating/drinking lemons alkalises your body (at least your gut anyway). There are other foods - e.g. cranberries which may have an acidifying effect on one part of the body and an alkalising effect on another part of the body. This is not too surprising because foods will be broken down in differnt ways, and different parts of the foods will be processed in different areas. One part of the food could be acid, and the other could be alkaline.

I took a quick look at the web page and it is pure sloblocks - I quote Gabe Mirkin MD:
"Your stomach is so acidic that no food can change its acidity"
What a load of tosh! What about antacids?!!?? Pure rubbish.

Look at any blood/urine/stools test and you will see that the PH of these things can all vary quiet considerably.

Acid Alkaline Imbalance

Over acidity, which can become a dangerous condition that weakens all body systems, is very common today. It gives rise to an internal environment conducive to disease, as opposed to a pH-balanced environment, which allows normal body function necessary for the body to resist disease. A healthy body maintains adequate alkaline reserves to meet emergency demands. When excess acids must be neutralized our alkaline reserves are depleted leaving the body in a weakened condition. The concept of acid alkaline imbalance as the cause of disease is not new. In 1933 a New York doctor named William Howard Hay published a ground-breaking book, A New Health Era in which he maintains that all disease is caused by autointoxication (or "self-poisoning") due to acid accumulation in the body:

"Now we depart from health in just the proportion to which we have allowed our alkalies to be dissipated by introduction of acid-forming food in too great amount... It may seem strange to say that all disease is the same thing, no matter what its myriad modes of expression, but it is verily so."

William Howard Hay, M.D.

More recently, in his remarkable book Alkalize or Die, Dr. Theodore A. Baroody says essentially the same thing:

The countless names of illnesses do not really matter. What does matter is that they all come from the same root cause...too much tissue acid waste in the body!
-- Theodore A. Baroody, N.D., D.C., Ph.D.

Understanding pH

pH (potential of hydrogen) is a measure of the acidity or alkalinity of a solution. It is measured on a scale of 0 to 14—the lower the pH the more acidic the solution, the higher the pH the more alkaline (or base) the solution. When a solution is neither acid nor alkaline it has a pH of 7, which is neutral.

Water is the most abundant compound in the human body, comprising 70% of the body. The body has an acid-alkaline (or acid-base) ratio called the pH, which is a balance between positively charges ions (acid-forming) and negatively charged ions (alkaline-forming.) The body continually strives to balance pH. When this balance is compromised many problems can occur.

***It is important to understand that we are not talking about stomach acid or the pH of the stomach. We are talking about the pH of the body's fluids and tissues, which is an entirely different matter. ****

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, you can determine your pH factor quickly and easily in the privacy of your own home. If your urinary pH fluctuates between 6.0 to 6.5 in the morning and between 6.5 and 7.0 in the evening, your body is functioning within a healthy range. If your saliva stays between 6.5 and 7.5 all day, your body is functioning within a healthy range. The best time to test your pH is about one hour before a meal and two hours after a meal. Test your pH two days a week.

Most people who suffer from unbalanced pH are acidic. This condition forces the body to borrow minerals—including calcium, sodium, potassium and magnesium—from vital organs and bones to buffer (neutralize) the acid and safely remove it from the body. Because of this strain, the body can suffer severe and prolonged damage due to high acidity—a condition that may go undetected for years.

Mild acidosis can cause such problems as:
Cardiovascular damage, including the constriction of blood vessels and the
reduction of oxygen.
Weight gain, obesity and diabetes.
Bladder and kidney conditions, including kidney stones.
Immune deficiency.
Acceleration of free radical damage, possibly contributing to cancerous
mutations.
Premature aging.
Osteoporosis; weak, brittle bones, hip fractures and bone spurs.
Joint pain, aching muscles and lactic acid buildup.
Low energy and chronic fatigue.

pH and Bone Loss:
Urine pH

The results of urine testing indicate how well your body is assimilating minerals, especially calcium, magnesium, sodium and potassium. These are called the "acid buffers" because they are used by the body to control the acid level. If acid levels are too high, the body will not be able to excrete acid. It must either store the acid in body tissues (autointoxication) or buffer it—that is, borrow minerals from organs, bones, etc. in order to neutralize acidity.

Saliva pH

You'll also want to test the pH of your saliva. The results of saliva testing indicate the activity of digestive enzymes in your body, especially the activity of the liver and stomach. This reveals the flow of enzymes running through your body and shows their effect on all the body systems. Some people will have acidic pH readings from both urine and saliva—this is referred to as "double acid."

Keeping the Balance Right for Excellent Health

Your body is able to assimilate minerals and nutrients properly only when its pH is balanced. It is therefore possible for you to be taking healthy nutrients and yet be unable to absorb or use them. If you are not getting the results you expected from your nutritional or herbal program, look for an acid alkaline imbalance. Even the right herbal program may not work if your body's pH is out of balance.


What if I'm Acidic?

By far the most common imbalance seen in our society is over acidity. If your urine and/or saliva test below 6.5 pH incorporate the following. Be sure to monitor your progress with easy-to-use pH test strips:

1. Anything green is alkaline: Eat or juice lots of deep green vegetables. Eat more fruits and vegetables and less animal products.

2. Enzymes are essential. Take 2 Ultimate Enzymes with meals each day and three on an empty stomach.

3. Restore Your Body by eliminating toxins. Our bodies get loaded down with toxins from the foods we eat that have been sprayed with various poisons. The toxins go into our body and they cannot escape because the pores of our skin have been clogged from the oils that are in soap products made from animal fat. The Masters Miracle Soap cleanses the body from all these oils and waxy residues which will clear the pores of the face, body and scalp.

4. Cleanse as needed: twice a year for liver, bowel and kidney detoxification.
