Many
health authorities advise against eating salt. My experience is that if one eats a diet of natural
foods high in magnesium and only uses sea salt, most people will not have
difficulty with salt. In
fact, natural sea salt is a very healthful product that most people need more
of to supply many important trace minerals.
This
article discusses the differences between refined and natural salt, salt and
magnesium, metabolic types and their sodium needs, salt and high blood
pressure, monosodium glutamate and what to do if you are salt-sensitive.
WHAT IS NATURAL SEA SALT?
History. Humanity has been eating unrefined salt
for thousands of years. The word
'salary' comes from the same root as the word salt because it was such a
valuable commodity it was used for currency. Salt is more important in hot climates, where significant
amounts of sodium are lost in sweating.
Sources. Most unrefined sea salt usually comes
from salt mines. It is washed and
strained. It is called sea salt as
the mines were usually former sea beds.
A few brands such as Celtic Salt are harvested from the sea. This is a good product, but products
harvested from the sea are much higher in some toxic metals such as mercury
that is found in the oceans today, but was not in the oceans as much millions
of years ago when the salt beds were formed. Therefore, I do not recommend salt that is harvested from
the oceans today.
Effects. Natural salt is generally a very
healthful product. Unrefined sea salt is an important source of minerals. This is especially today,
as the food supply is mineral-deficient due to hybrid crops, modern agriculture
methods and food processing and refining.
Unrefined
salt has little or no effect on blood pressure. It helps maintain electrolyte and osmotic balance. It also has an alkalinizing effect on
the body and is an extremely yang food in Chinese medical terminology.
The
sodium it contains is critical for osmotic balance and to solubilize
other minerals in the blood.
Deficiency of sodium causes other minerals to become biounavailable
and precipitate into the soft tissues and elsewhere.
All the
above are very positive reasons to eat salt on food.
Avoiding unrefined sea salt is ridiculous, and I
recommend unrefined salt for all but a very few people who do not tolerate it
until their bodies become healthier.
IODINE ENRICHMENT OF SALT
Partly
due to the insane practice or refining table salt, the government forces salt
companies to enrich all table salt with iodine. This is a positive benefit of table salt, but the only
benefit. See below for more on
refined or table salt.
WHAT IS TABLE SALT?
Common
table salt is a highly refined product and one of the worst junk foods. Virtually all its the trace minerals
are missing, so that it is almost pure sodium chloride. The trace minerals are removed and sold
separately. This profits the salt
company and leaves our bodies impoverished. This product should be banned completely, and our health
would be far better.
Its
unbalanced mineral content actually causes more mineral imbalances, as it is
too high in sodium and very low in calcium and magnesium, two vital minerals
today that can be obtained to a degree from salt.
If
mineral depletion is not bad enough, common table salt often has aluminum, a
toxic metal, added as a flowing agent.
It is also often bleached for whiteness with other toxic chemicals. It is an unbalanced, toxic product that
should be totally avoided.
SALT AND
MAGNESIUM
One
of the most important minerals missing from refined table salt is
magnesium. Magnesium is required
for over 1000 enzymes in our bodies, and is deficient in most people's diets.
Magnesium
is sadly missing from most refined foods.
Milling wheat to make white flour removes 85% of the magnesium. Refining sugar cane to make white sugar
removes 98% of the magnesium.
White flour, white sugar and refined table salt are unfortunately ÒstaplesÓ
of the American diet and more and more common in other nations as well.
Magnesium
has a balancing effect on sodium.
Magnesium has a relaxing influence on the heart, which is one reason a
shot of magnesium it is often the first ÒdrugsÓ given during a heart attack.
Magnesium and blood pressure. The blood
pressure-raising effect of table salt can be due to its high content of sodium
with not enough magnesium to balance it.
This has a magnesium-lowering effect that can constrict the arteries and
raise blood pressure.
Sea salt
contains plenty of magnesium, which is why it usually does not affect blood
pressure at all, or does so much than table salt and should be eaten by most
people. Also, If one's magnesium
status is adequate because one has other food sources of magnesium, salt-eating
will have less effect or no effect on blood pressure. However, other food sources of magnesium are rare, which is
why everyone on a nutritional balancing program receives a magnesium
supplement.
ARE THE MINERALS IN SALT BIOAVAILABLE
Some
people claim that since salt is not a live food, one cannot obtain the minerals
from salt. This is simply not
true. The minerals may not be as bioavailable as they are in foods, and this is true. However, the body has quite an ability
to chelate or bind inorganic minerals, especially
those found in some sea salts.
For this
reason, eating some sea salt every day is a wonderful and necessary means of
supplementing oneÕs mineral intake.
One must, however, have healthy digestion and a low stomach pH to absorb
the minerals well. This is one
reason every adult on a nutritional balancing program takes a digestive aid,
regardless of age or health status.
Children may need digestive help, but usually not as much as
adults. Digestive aids often do
not taste good, so they may not get one for this reason. However, they are helpful for most
children as well.
SODIUM AND SALT IN THE AMERICAN DIET
Sodium sources. Many natural foods contain sodium. Excellent sources are vegetables of all
kinds such as carrots and beets.
Red meat, poultry, eggs and fish are also excellent sources. Kelp is another excellent natural
source.
Refined
foods are often deficient in natural sodium, but are loaded with refined
salt. Many refined foods are bland
or even tasteless because of the poor quality of their ingredients. In an effort to spice them up, table
salt is often added in great quantity.
Among the
most salt-laced foods are French fries, chips, pastries, salted fish, processed
meats, relishes and canned soups.
Many other refined foods contain a surprising amount of refined table
salt.
Since
the same foods are magnesium-deficient, the combination is very unhealthful and
not surprisingly can cause problems, especially if eaten repeatedly.
An
exception are the organic corn chips, especially blue corn chips, that are
labeled as containing sea salt. I
hope more chip companies will move in this direction, as the sea salt is a much
healthier product.
SODIUM AND SLOW OXIDATION.
Sodium
levels in the blood usually remains in a narrow range, even when significant
pathology is present. This is not
true of sodium in the hair. Here
sodium ranges from a low of 1 or 2 mg% to several hundred mg%.
Low sodium on hair tests. Most people's hair
analyses reveal very low levels of sodium. We find this is not usually related to salt intake, but to
the adequacy of the adrenal glands.
Aldosterone secreted by the adrenals causes
sodium retention in the tissues.
Slow oxidation and low blood pressure. The mineral pattern
characterized by low tissue sodium and potassium is called slow oxidation. These individuals often crave salt and
salty foods. Many have a low blood
pressure, in part due to low sodium that contributes to a low blood
volume.
Low blood
pressure may also be due to underactivity of the
adrenal glands. Adrenal hormones
cause constriction of the arteries, which raises blood pressure.
Sea salt particularly good for slow oxidizers. Consuming some sea salt
may help raise the sodium level slightly in slow oxidizers, as these individuals
are excreting excessive sodium.
Consuming sea salt is strongly recommended for these people unless they
are salt-sensitive due to other pathology. However, to permanently and significantly raise their tissue
sodium, they must improve their adrenal glandular activity.
Slow
oxidizers who are eating a magnesium-rich diet may have up to 200 mg of sodium
daily with no adverse effects.
Some do well on more. This
is not a lot compared to that found in a diet of salt-laden refined foods. However, it is certainly not an
avoidance of salt.
SODIUM AND FAST OXIDATION
In
some people, the hair tissue sodium level may be elevated. The most common metabolic pattern with
this is a fast oxidation state. It is seen most commonly in young
children. In fact, we all begin
life with a high tissue sodium level.
In
adults, it is more likely a secondary stress pattern associated with excessive
levels of toxic metals affecting the adrenals, kidneys or pituitary gland. Excessive sympathetic nervous system
activity may also affect the adrenal glands.
Toxic metals and sodium levels. The presence of
toxic metals, especially cadmium, mercury, lead, arsenic, copper, manganese,
iron or aluminum will raise the hair sodium level. This is due to a toxic effect on the kidneys, adrenals and
other organs.
These
metals irritate the kidneys and adrenals.
Physiological forms of the minerals manganese and iron do not have this
effect, only a toxic form that is probably and oxide, that is quite common
today.
Most
often, the hair sodium level will drop when the toxic metals and toxic forms of
manganese and iron are eliminated from the body. At the same time, edema or swelling of the tissues often
disappears and the blood pressure often decreases if it was elevated.
Salt sensitivity. If the tissue sodium
level is elevated on a tissue mineral test, one may be somewhat salt
sensitive. This is not a problem
with sea salt, but a pathology caused usually by toxic metals or toxic
chemicals in the kidneys, pituitary or adrenal glands.
Other
very rare reasons for sea salt sensitivity include a hormone-secreting adrenal
tumor or CushingÕs disease.
WHAT TO DO IF ONE IS SALT-SENSITIVE
1. Avoid table salt completely. Everyone should avoid table salt. Many salt sensitive people can tolerate
some unrefined sea salt.
Restaurants can be a problem, as salt is hidden in many dishes. One can ask in some restaurants for low
sodium or sodium-free meals.
2. Eat only natural and unrefined grains
and no white sugar or white flour.
This way one will obtain significantly more magnesium from food, which
may help reduce salt sensitivity.
3. Supplement with magnesium. Quality magnesium supplements include chelates, citrates, glycinates, aspartates and orotates. The latter two contain less magnesium
per tablet, though they are well-absorbed.
Taking
a magnesium supplement may well reduce salt sensitivity. Magnesium is very safe. Excessive amounts will cause
diarrhea. Some physicians give
magnesium to bowel tolerance, though I believe this is excessive in some cases.
4. Go on a nutritional balancing program to
remove toxic metals and restore a balanced body chemistry. Salt
sensitivity may indicate excessive levels of toxic metals or a fast oxidation
rate. This can be assessed with a
hair mineral analysis.
Most
people have some toxic metals, regardless of whether they are revealed on tests
or not. A nutritional balancing
program and infrared sauna therapy are most helpful to remove toxic metals and
chemicals that can affect the kidneys, adrenals and pituitary, and contribute
to salt sensitivity.
ADDING SALT TO DRINKING WATER
This
is a newer Òdetoxification procedureÓ that I do not endorse at all. It is quite dangerous, in fact, though
it starts our harmlessly enough.
Adding salt to drinking water will cause the removal of a few toxic
metals by an osmotic mechanism.
The problem is that it may also remove vital or essential minerals
slowly and insidiously. It can
also subtly dehydrate the body.
Therefore, I do not recommend this procedure at all.
PSYCHOLOGICAL ASPECTS OF SODIUM
Sodium
is sometimes called the volatility mineral. People with a high sodium level often have a volatile or
elevated blood pressure and their personality may also be volatile. Elevated tissue sodium is related to
the alarm stage of stress, also called a fight-or-flight reaction.
Sodium
is very yang in Chinese medical terminology. Yang is the quality of being warm, hard and contracted or
centripetal.
People
with a high level of sodium in relation to potassium are often leaders,
starters, pioneers, outgoing, active and positive. When sodium is in excess, they may become volatile, angry or
paranoid.
MONOSODIUM GLUTAMATE
A
product related to table salt is monosodium glutamate or MSG. This food additive is widely used as a
flavor enhancer in thousands of prepared foods. It is also used widely in Chinese cooking, soups and other
processed foods.
It causes
headaches and other symptoms in many people. Glutamic acid is a
pro-inflammatory amino acid. The
sodium in MSG is not balanced by magnesium or other trace minerals, so it too
has a pro-inflammatory effect.
If
one is deficient in magnesium, the effect is even worse. I suggest avoiding all monosodium
glutamate. For more information
about this, read MSG on this website.
