Hello,

We occasionally hear that some foods is acidic, alkaline or
water-attracting. Sometimes, these are acid, alkaline forming and
water-creating. Some other say, these are acid, alikaline ash forming
or hydrating/dehydrating. What does it mean?

Are these related to their different effect on digestive pH/water and
internal pH/water status?

Whether these create somewhat opposite pH/water effects in digestive
tract and in internal enviroinment?

Best wishes.

I wouldn't even call this "pseudo-science."  If there is an effect, it
must be very minimal, except perhaps in particular "diseased" states.
You seem to be at a point I was a few years ago, trying to sort out all
the contradictory information that is presented through the media.

To sum up my conclusions at this point: the body can take care of
itself, if you give it what it needs and avoid dangerous substances,
like anything made with highly unsaturated oils and anything with
cholesterol that is likely to have been oxidized.  After that, it's
simple: electrolyte minerals in absorbably forms, ample stomach acid,
vitamin D or sufficient sunlight.

The academic seems NOT to know his history very well. :(

http://tutorials.naturalhealthperspective.com/allopathy.html
"The system of medicine prevailing in the Colonies in the years
immediately preceding the American Revolution, was that of the Dutch
physician and teacher Hermann Boerhaave (1668-1738). The Boerhaavian
theory of disease explained it in terms of chemical and physical
qualities, such as acidity and alkalinity, or tension and relaxation."

The rational for the above beliefs can be traced back to the allopathic
Boerhaavian system.

Don't you just love, loving science Monty?  Boerhaave sure did.

Just thought that you might want to know.

When we are born, our body is slightly alkaline. As we age, our bodies
loses the alkalinity slowly. It depends on what we eat. Lots of
chemical reactions in our bodies & the food after being metabolised
produces acidic organic substances. Most the junk foods we have are
acidic. You can do a litmus test.. you will be shocked.

Scientific studies have shown that acidic body conditions contribute to
cancer development & numerous degenerating diseases. A sickly person
has a lower pH level compared to a healthy individual. Fermentation of
milk by Lactobicillius bacterias turning lactose to lactic acid
protects the milk from invasion of other harmful bacterias. Acidic
conditions kill cells.

We drink more water than we eat. Over 60% of our cells is water. It is
natural to arrest this pH issue through administering of alkaline
water. This alkalinity is the result of minerals, namely the major
minerals: magnesium, calcium & potassium. It is right to conclude the
possibility of malnutrition issues in acidic persons. Malnutrition is
an imbalance in the body. We are talking about the electrolytes in the
fluids in the cells. The OH vs H in the water. If you add minerals to
distilled water, the they form OH anions, clustered & structured
molecules. They are smaller than the normal water molecules. Normal
water has a cluster of in 24 molecules. This size is too big to pass
through our cell membranes. Distilled water has a cluster of 10
molecules. Alkaline water has a cluster of 6 molecules. Our cell
membrane structure is about the size of 8 molecules in a cluster.
Ideally, alkaline water can diffuse into our cells better, does not
cause bloating. Furthermore, it is enriched with minerals. Alkaline
water has antioxidant properties due to OH... the hydroxyl anions.

There is an emphasis on taking greens & herbs because of their
alkalising effects. Lemon & organic apple cider vinegar are turn
alkaline after digestion. Just take lemon for instance. The citric acid
& potassium carbonate after digestion turns alkaline. That's why lemon
is the elixir of life in french folk medicine. Organic Apple Cider
Vinegar has potash ash that turn alkaline after digestion. Chives,
wheatgrass, barley grass has high mineral content that are very
alkalising. The issue is we are consuming far too few of these in our
diet. We have too much energy nutrients in our diet... too much bad
fats & excess proteins. It certainly make sense to add lemon & organic
vinegar to our drinking water. 2 lemons plus two teaspoons of organic
vinegar for every litre.

This is an interesting area of study. Holistic Nutrition.

Of course not.. this is nowhere found in my programme. I just typed all
that for the fun of it. Test the legitimacy of the information. I heard
it from someone too. I also look up companies selling water ionisers.
Roughly that is what they say. The information for lemon is from Dr
Jean Valnet's book... the father of aromatherapy. It does say critic
acid after digestion becomes alkaline. Potassium carbonate.. right...
is akaline compound to start with. Ash in the organic vinegar too. I
think not much issues with lemon & organic vinegar. The ionised water
is not really easy to understand. The technology of splitting water
atoms by electricity comes from Korea. Invented by a doctorate water
scientist. They managed to split water of normal pH into acidic &
alkaline waters with smaller molecular or atomic sizes. The resultant
water has bio-electricity or static charge that is capable of killing
microbes & is same charge as our stomach. The nutrients in the water
gets absorbed easily in the stomach. Doesn't have travel to our
intestines to absorption of nutrients. This type of water ionisers are
very common in Japan. The alkaline water can be used to infuse tea
leaves at room temperature without heat. High solvency. Powerful
antioxidant with lots of oxygen.This is not the conventional
electrolysis of water, splitting into hydrogen gas & oxygen gas. I have
seen this type of machine in Singapore. I have tried using the alkaline
water for my plants.. & they grow very well. The acidic water is good
the skin. The ionising machine generates both acidic & alkaline waters
at the same time like a filter. But the water loses their alkalinity &
acidic over time. Anyway, I guess I used some of the terminology
wrongly though. So spare me the terminology.You guys can look up
http://watershed.net/jupiter_dys.htm#4.
http://watershed.net/Jupiter-Overview1.htm. This is the official Korean
site... http://www.jupiterion.com/. they have won some many awards in

You can do a litmus test of your urine. It will be acidic. The kidneys
remove excess acid from the body.

Yet that doesn't mean acid causes illness. Very sick people often don't eat
well. Yet, eating too well often causes illness.

Except that the body pH is a pretty constant 7.36 to 7.44.

Unless the water you drink is naturally alkaline, there is nothing natural
about it.

Actually, alkilinity is the result of the OH- (hydroxyl group). You ought to
read a chemistry textbook.

Anions are not molecules. Again, you need to read a chemistry book. It is
not the calcium or magnesium that forms the OH groups, but rather the
carbonate or other anions that bind to the H+ in the water, and form excess
OH groups.

Our cell membranes are far larger than that. Our cell members surround our
entire cells.

This whole talk about the size of wataer clusters is totally irrelevent. The
pH inside our bodies is  a constant 7.4 (7.36 to 7.44 is the normal range).

Actually, because of the minerals like potassium, the fiber (nothing like a
clean larrge intestine) and because of the antioxidants, the pH of which is
not important.

No, it is because the French folk medicine people had no clue about what

That's news to the medical community as I thought you alternatives were

Acidosis outside the norm denotes disease.

All cases of lactic acidosis have nothing to do with Lactobacillis.

Most cases of metabolic acidosis and none of the cases of respiratory
acidosis have anything to do with malnutrition.

Water is in equilibrium at a pH of 7 and doesn't need other ions to become
ionized. Other compounds are have dissociation constants as well which
depends on that particular compound.
Size has nothing to do with it.

Normal

How is water absorbed in the intestine when one drinks water.

Distilled water has a cluster of 10

Water is water and you confuse ionic forms from the water molecule.

ALkaline water? Water is at a pH of 7 and is neither acid nor alkaline. You
have chemicals that when put in water then by definition is not water
anymore. It contains water plus the additional ions or minerals.
Oxidation is defined as the gain of oxygen or the loss of hydrogen.
You want your body perfused with oxygen to avoid lactic acidosis. Oxygen is
the final receptor of Hyrogen in the electron transport cellular respiration
resulting in the formation of water.
Mineral absorption is under hormonal control as anybody with hemochromatosis
can tell you.

After ingestion? First you say that only alkaline water is absorbed and
acids are too big to pass through the membranes.
The truth is that the stomach has acid that can burn your skin right off and
so all foods become acidic in the stomach. The intestinal secretions
neutralize the acid with alkaline solutions via the gallbladder and
pancrease. Intestinal contents are thus more alkaline. This happens
regardless of what you eat.

When we take any alkaline food or antacid (not alk. ash forming), or an
acidic food--how do these effect internal pH? Whether body balances it
instantly or not is a different issue.

Something is given on these sites but beyond my head;

http://en.wikipedia.org/wiki/Gastric_acid

http://arbl.cvmbs.colostate.edu/hbooks/pathphys/digestion/stomach/parietal.html

Furthur, can there be progressive damages or effects due to prolong
intake of either acidic or alkaline foods which in long run may result
some collapsing effects--means body become unable to handle at any
date? So how should we avoid it?

Don't really know what you are asking. The bodies pH is keep within a narrow
range and excess acid is excreted. Urine pH is in the 5 range and the blood
in the pH 7.4.
People with disease such as renal failure are unable to excrete the total
acid load so they recommend less food minimizing the acid load.
I don't know a any normal person who's blood or internal pH changes because
they ate something. Those that are impacted by eating something have disease
and it is the disease that is the limiting factor.
There are several over the counter stuff like calcium carbonate which isn't
food that can give you milk alkali  syndrome when taken in excess amounts.
It is the combination of calcium and alkali that causes the problem. This
problem was eliminated by newer nonabsorable alkali and H2 blockers, proton
inhibitors etc.
These are not food.
Without any context of what you are getting at then it becomes too general
to comment anything specific.

Not of acidity but if one becomes allergic or sensitive to certain foods
then yes you can have chronic damage such as celiac sprue or anaphylaxsis
IgE allergies.
There can be consequences of chronic acidosis or alkalosis due to disease
but that is in the nature of disease and not in health.

"The epithelium of the stomach is intrinsically resistant to the damaging
effects of gastric acid and other insults. Nonetheless, excessive secretion
of gastric acid is a major problem in human and, to a lesser extent, animal
populations, leading to gastritis, gastric ulcers"

This is taken out of context. The stomach is resistant to acid and something
must happen to change the normal physiology and that being disease such as
an infection of bacteria eating at the stomach and causing the acid damage
or a tumor of gastrin producing cells with over production of acid which is
rare.

Acid & Base balance depends upon the state of the body....& environment
also..

     If a person is living in high altitude where pO2 is very less,
he/she tend to breathe rapidly & lose CO2 from the body more than
normal. This results in acidosis, which is taken care of by Kidneys....
Kidneys are the powerful filtering organs in our body... They help in
maintaining Homeostasis. They break Water into H & OH with the help of
enzymes, H is excreted & most of OH is reabsorbed. In this case low pH
foods won't harm much, but just think if they are consumed in large
doses [like aerated drinks Eg: Coke] salts formed in nephrons aren't
dissolved but deposit as stones obstructing the urinary tract... Here
alkaline foods are very helpful, they reduce burden on kidneys &
dissolve the salts & their precipitation is prevented....
     High acid fod in some cases cause indigestion. pH of juice in
stomach is very low[about 2-3]. Duodenum delays food entering it from
the stomach if the pH is very low. Meat is acidic then Veg, hence we
feel our stomach filled for more time when we eat meat than when we eat
same amount of Veg food which is alkaline. This indigestion may result
in vomiting, etc... As chyme stays longer in stomach with low pH,
tendency to develop gastritis, ulcers increase.

"The pH of gastric acid is 2-3 in the stomach lumen, the acidity being
maintained by the proton pump, a H+/K+ ATPase. The parietal cell
releases bicarbonate into the blood stream in the process, which causes
the temporary rise of pH in the blood, known as alkaline tide."
http://en.wikipedia.org/wiki/Gastric_acid

The above quote indicates that when acid is secreted in to the stomach,
bicarbonate  is released into the blood stream in the process, which
causes the temporary rise of pH in the blood, known as alkaline tide.
More acid can be secreted, if we take alkaline food or antacids(not
acid blockers) and more bicarbonate will be released into the blood in
this process. So it tells that when we take alkaline food or antacids,
we make our blood alkaline, may be for some time which then body
balances. Now when we take acidic foods, I think less HCl will be
secreted resulting bicarbonate not released in blood. It tell us that
alkaline foods or antacids are alkalinser to blood and urine whereas
acidic foods are acidic. Is it ok? This is one mechanism. Other
mechanism can be what we absorb and how those absorbed substances will
effect to internal Ph?

Under above considerations, how can you assess the effects from
antacids and acid blockers(proton pump blockers etc.) on our internal
pH? I think, it can be alkaline from antacids and nil or acidic from
acid blockers. OK???

Hyperventilation causes a respiratory alkalosis, not acidosis. CO2 =
acid as far as the body's concerned so getting rid of it is like
getting rid of acidity.

More like pH 1-2.

The acidity from foods is tiny compared to the acidity already in the
gastric juice. Any effects occur after the food has been digested and
absorbed.

When stomach atmosphere is less acidic or slightly alkaline either due

Ozone, like chlorine, oxidizes organic matter, which is how both kill
microbes in treated tap water.  IIRC, ozonation is used instead of
chlorination in many municipalities in Europe.  The benefit of drinking
ozonated tap water is more or less the same as drinking chlorinated
tap water -- pathogens of water-borne diseases have been killed.

Chlorine and ozone are added in parts-per-million quantities to
purify tap water, so no, ozonation doesn't convert the tap water
into H2O2 any more than chlorination turns tap water into laundry
bleach.

Ozonation is more expensive than chlorination (actually, most North
American municipalities use chloramine, not chlorine, because it
remains active in the water for longer) but there's some belief that
the reaction products of chlorine with common organic pollutants may
be carcinogenic.  Nobody knows if this has any significant effect on
incidence of cancer, but in some municipalities people are willing to
pay for the difference in cost.  IIRC, most of these are areas where
the sources of tap water are heavily polluted with organics, notably
the Rhine valley.  Some of these municipalities have to use charcoal
filtration to get the organics levels down to potable standards.

My information may be out of date -- a lot of work has been done to
clean up the Rhine and other European rivers, so I welcome correction
from the knowledgable.

If someone is trying to sell you ozonated water, or water ozonation
equipment for its alleged health benefits, they are ripping you off,
unless your water comes from a contaminated well, in which case I
recommend you talk to your local public health people who can test
your water and give you impartial advice.

Ozone treatment is becoming more common in the US, but is far from
universal.

I lean towards the belief that it is, albeit slightly; there is some
decent evidence that it increases the odds of bladder cancer.  Ozone
hasn't simply replaced chlorination because it's expensive and your
average water treatment district is not so flush with cash that they
can just decide to rip out their working chlorination system and
replace it.

However, even if the cancer cases do rise a bit, we are weighing this
against the costs of NOT treating the water, which would make your
local water system a fine conduit for giving you typhoid, cholera,
etc.

Agreed.  However, if you're someone who is worried about the presence
of chlorine (and its byproducts) in your local water supply, filters
will remove it.

This is just some sort of urban myth.  In old or "diseased" people,
there can be lactic acid buildup because cells are stressed and can't
produce energy effectively - that is a reality.  You can read about it
in the scientific literature.  It is more likely that old people who
have not stressed their bodies to a considerable degree are lacking in
stomach acid production.  This can lead to very real physiological
imbalances and deficiencies.  Taking calcium carbonate supplements, as
many old people do, with too little stomach acid production, is a
proverbial recipe for disaster, for instance.  But to Kumar: why not do
some research of your own on www.pubmed.com - just type in some key
words and start reading through the abstracts.  Then ask questions
here.  Otherwise, you are wasting your time on all the oddball claims
there are these days.  It's true that sometimes the establishment gets
things very wrong, as in the "essential fatty acid" claim, though no
one even is willing to state it as a hypothesis, so it's difficult to
say exactly what they are contending, but the evidence is there, and
the data is usually accurate.  It's the interpretations that are all
too often inconsistent with the raw data.

Your kidneys are able to excrete excess acid and base. So you don't need to
worry about the pH of foods and drinks. Your kidneys handle this

Jeff, I wonder if the poster is asking in the context of stones in the
