Is Your Body's PH Levels an Indicator of Health?

It has been stated that if the condition of our extra cellular fluids, especially the blood, becomes acidic, our physical condition will first manifest tiredness, proneness to catching colds, etc. When these fluids become more acidic, our condition then manifests pain and suffering such as headaches, chest pains, stomach aches, etc.
According to Keiichi Morishita in his Hidden Truth of Cancer, if the Blood develops a more acidic condition, then our body inevitably deposits these excess acidic substances in some areas of the body, thus the blood will not be able to maintain an alkaline condition which causes these areas such as the cells to become acidic which lowers in oxygen. As this tendency continues, such areas increase in acidity and some cells die; these dead cells then turn themselves into acids.
However, some other cells may adapt in that environment. In other words, instead of dying - as normal cells do in an acid environment - some cells survive by becoming abnormal cells. These abnormal cells are called malignant cells. Malignant cells do not correspond with brain function or with our own DNS memory code. Your body's pH level is a large indicator of your alkalinity.
Why should we be concerned about pH levels? Since most of the body is water-based (50-60%), the pH level has profound effects on all body chemistry, health, and disease. All regulatory mechanisms (including breathing, circulation, digestion, hormonal production) serve the purpose of balancing pH, by removing caustic metabolized acid residues from body tissues without damaging living cells. If the pH deviates too far to the acid side or too far to the alkaline side, cells become poisoned by their own toxic waste and die.
Just as acid rain can destroy a forest and alkaline wastes can pollute a lake; an imbalanced pH can corrode all body tissue and slowly eat into the 60,000 miles of veins and arteries like corrosives eating into marble. If left unchecked, an imbalanced pH will interrupt all cellular activities and functions, from the beating of your heart to the neural firing of your brain.
The body is largely made up of water, a medium that is biologically useful in allowing nutrients, oxygen and bio-chemicals to be transported from place to place. This water-based medium can have either acid or alkaline properties that are measured by a graduated scale called pH (for potential hydrogen). Wherein 1.0 to 6.9 is considered acidic, 7.0 is neutral and 7.1 to 14.0 is alkaline.

What is the pH of some popular drinks and food?
Colas	1.0	Coffee	5.0	Cereal Corn	2.5
Soft drinks artificially sweetened	1.0	Salt Refined	1.5	Meat	2.5
Sugar	1.0	Wheat Refined	1.5	Fried Potato Chips	3.0
Liquor	1.0-2.0	White Rice	1.5	Chicken & Fish	3.0
The pH of fruits and vegetables
Melons	7.0	Pineapple	6.5	Avocados	6.0
Asparagus	6.5	Fresh Fruit Juices	6.5	Citrus Fruits	6.0
Most Vegetables	5.0-6.0	Potatoes with Skin	5.5	Almonds	5.0

Even the experts, who acknowledge that a neutral or slightly alkaline pH is good, disagree on what this means with regard to body fluids. For example, some researchers consider a slightly acidic urine pH to be normal (healthy) because it might indicate that the body is eliminating acids that are a natural product of metabolism. Other experts maintain that the urine should be close to neutral or slightly more alkaline. Acid/alkaline balance is extremely important to normal physiology.
For example, the blood will maintain a slightly alkaline range of 7.35 to 7.45. Extended pH imbalances of any kind are not well tolerated by the body. The management of the pH factor is so important that the body's primary regulatory systems (especially breathing, circulation and eliminations) closely regulate acid-alkaline balance in every cell and system of the organism. Some researchers believe that high acidity can deplete bones because the body has to steal alkalizing minerals (especially calcium) from bones to keep the blood from dropping into the acid range.
Thus acid/alkaline balance may be relevant to diseases such as osteoarthritis and osteoporosis. Alkalinity can be increased by consuming less meat and sweets in place of eating more vegetables and fruits. Although eating fruit to increase alkalinity may seem to be a contradiction because some fruits (especially citrus) are acidic outside the body, digestion uses up their acidic components, leaving an alkaline residue (ash). Thus the net effect is an alkaline-producing benefit for the body.
