Brain health dramatically improved by intake of
omega-3 fatty acids and fish oils (Part
II) |
| |
|
The experts speak on omega-3 oils and brain
health: |
Many nutrients, such as the B vitamins, are critical to proper
brain function. Fatty acid deprivation works against optimal
brain power. Docosahexaenoic acid (DHA) is a long-chain fatty
acid found in fish, egg yolks, and marine algae, and is the
predominant omega-3 fatty acid in brain tissue. As the brain is
dependent on dietary fatty acids, reductions in DHA content of
the diet may contribute to degenerative changes in the nervous
system. The delicate balance of electrolytes also controls the
electrical activity within the brain. For this reason, many of
the tests previously mentioned relating to nutrition, toxic
load, and stress have relevance when attempting to better
understand sub-optimal brain function.

DHA remains the most important brain fat throughout life. Low
levels of DHA are associated with an increased risk of memory
loss. Dr. Michael A. Schmidt reports in Smart Fats that,
according to data collected in the long-term Framingham Heart
Study, adults with low levels of DHA have a greater likelihood
of developing dementia in their later years. Other studies have
indicated these adults are twice as likely to develop dementia
as those with high levels of DHA. And a 1997 study demonstrated
that low DHA blood levels are an important risk factor for
Alzheimer's disease.

The implications of omega-3 deficiency on the brain are
profound and span the entire human life cycle. Beginning in
pregnancy, premature birth and its potential neurologic
complications may result from omega-3 deficiency. Babies who
are bottle-fed or born from omega-3-deficient mothers will lack
the omega-3 fatty acids necessary for optimal cognitive and
visual development. Children deprived of omega-3s may have less
ability to pay attention and control impulsive behavior and may
be at higher risk for depression. Teenagers and adults with
omega-3 deficiency may be more prone to hostility or violence.
In aging, the loss of omega-3 fatty acids in the brain may
result in a higher risk of stroke, memory problems, or
dementia. Individuals of any age without adequate amounts of
omega-3 fatty acids in the brain and body may also be at higher
risk for depression, bipolar disorder, and possibly other
psychiatric disorders.
The Omega3 Connection by Andrew L Stoll MD, page

Omega-3 fatty acids are beneficial because they provide
fluidity to cell membranes and improve communication between
brain cells. Omega-3s also reduce the clotting ability of
platelets, thus potentially decreasing the incidence of heart
attacks and strokes. Two very important omega-3 fatty acids are
eicosapentanoic acid (EPA) and docosahexanoic acid (DHA). They
are found in seafood, especially mackerel, salmon, striped
bass, rainbow trout, halibut, tuna, and sardines. In the body,
DHA is found mostly in the brain, retina, and in sperm. DHA
plays an important role in vision. B) Omega-6 fatty acids are
made from linoleic acid, a fatty acid found in vegetable oils
such as corn, safflower, cottonseed, and sunflower. Mayonnaise
and salad oils normally contain a great amount of omega-6 fatty
acids. Unlike omega-3s, which are concentrated in the brain,
omega-6s are found in most tissues in the body. The double bond
of an omega-6 fatty acid starts six carbons from the left. Most
Americans generally have a much higher intake of the omega-6s
than the omega-3s.
Mind Boosters by Dr Ray Sahelia MD, page

One of the most important of these fats is called
docosohexiaonic acid or DHA. This fat plays an important role
in the formation of the synaptic connections within the brain.
These connections allow the various parts of the brain to
communicate with each other and communicate with the body as
well.
Health And Nutrition Secrets by Russell L Blaylock MD,

Adequate levels of DHA are required for proper brain and eye
development and function. DHA is important for signal
transmission in the brain, eye, and nervous system.
Heart Disease by Burton Goldberg, page
46
DHA is not only very critical in brain development but also in
maintenance of the brain later in life. Don't forget, the brain
is constantly restructured throughout life, even into the
extremes of age. Unfortunately, because of food-processing
methods and industrial raising of animals as meat sources, most
omega-3 fatty acids have been removed from our foods.
Health And Nutrition Secrets by Russell L Blaylock MD,
page 315
These fatty acids reduce inflammation, protect against the
abnormal clotting associated with heart attacks, inhibit
cancer, and protect brain function. There may be other
benefits, too: a 1992 study published in the journal Lancet,
for example, suggested that omega-3 fatty acids prolong
pregnancy by a few days and improve birth weights.
Ask Dr Weil by Andrew Weil MD, page 92
The basic building blocks of our brain cells are essential
fatty acids such as EPA and DHA. These fatty acids are also
used as fuel for brain metabolism and help control the chronic
inflammatory processes involved in degenerative brain
disorders.
Disease Prevention And Treatment by Life Extension
Foundation, page 22
In the last month of pregnancy and first month of neonatal
life, omega-3 fatty acids are rapidly incorporated into the
brain of the baby.
8 Weeks To Optimum Health by Andrew Weil MD, page

DHA is found in foods that many people have given up in the
name of good health, such as organ meats and eggs. It is also
abundant in fatty fish, like salmon, mackerel, sardines, and
albacore tuna; however, most Americans do not eat significant
quantities of fish. DHA is found in high concentration in the
gray matter of the brain and the retina of the eye. It is also
instrumental in the function of brain cell membranes, which are
important for the transmission of brain signals.
Earl Mindell's Supplement Bible by Earl Mindell RPh
PhD, page 44
A major building block of human brain tissue and the primary
structural fatty acid in the gray matter of the brain and the
retina, DHA is vital for brain and eye health. Studies indicate
that DHA may have cardiovascular benefits as well as
neurological benefits. Although the body can convert
alpha-linolenic acid into DHA, the amount produced is minimal
so you are better off getting DHA directly from food.
Fight Back With Food by Readers Digest, page
73
Studies strongly suggest that DHA, a fatty acid, is
essential for normal mental function. These fatty acids may
have many jobs in the body, including a possible role in the
production of neurotransmitters. In fact, research has shown
that primates fed a diet low in this particular fat actually
became more violent and aggressive. The same may be true for
humans.
Earl Mindells Secret Remedies by Earl Mindell RPh PhD,
page 110
When it comes to providing protection for the brain and
encouraging overall brain health, DHA may be the more important
fatty acid. Studies found that DHA supplementation
significantly decreased the number of reference memory errors
and working memory errors in aged male rats as well as in young
rats.
Disease Prevention And Treatment by Life Extension
Foundation, page 22
Essential fatty acids, especially docosahexaenoic acid (DHA),
are important in neurological repair because the brain is
composed almost entirely of fatty acids. They also have very
strong anti-inflammatory properties.
Disease Prevention And Treatment by Life Extension
Foundation, page 531
Omega-3 essential fatty acids: These beneficial fats maintain
the fluidity of nerve cell membranes. They also are important
for building cells; for preserving brain, nerve, and eye
function; and for lowering the risk of high cholesterol,
cardiovascular disease, and cancer. We recommend taking 1,000
to 3,000 milligrams of omega-3s in supplement form every day.
The
Rhodiola Revolution by Richard P Brown MD and Patricia L
Gerbarg MD, page 215
The brain is 60 percent fat—and essential fatty acids are an
integral component of this fat. Perhaps the most critical of
these essential fatty acids is DHA, which is necessary for
memory and learning. Also, omega-3 fatty acids have an
antiinflammatory effect, which appears to be important for
brain health.
Natural Physicians Healing Therapies by Mark Stengler
ND, page 188
The latest research from Japan demonstrates why DHA is also
necessary to maintain optimum brain functioning in adults, and
why it could turn out to be critical for the prevention and
possible reversal of Alzheimer's disease!
Underground Cures by Health Sciences Institute, page
104
When the level of DHA drops, reducing axon flexibility, the
arms become hardened and signals are transmitted more slowly.
Researchers in Japan have recently observed that the absence of
DHA is associated with many cognitive and mental-health
conditions, such as depression, schizophrenia, and dementia of
the Alzheimer's type.
Underground Cures by Health Sciences Institute, page

The basic building blocks of your brain cells are essential
fatty acids such as EPA (eicosapentaenoic acid) and DHA
(docosahexaenoic acid). These fatty acids are also used as fuel
for brain metabolism and they help control chronic inflammatory
processes involved in degenerative brain disorders. When it
comes to protecting brain health, DHA may be the more important
fatty acid. One study found that DHA supplementation
significantly decreased the number of reference memory errors
and working memory errors in aged male rats and in young
rats.
Power Aging by Gary Null, page 173
The omega-3 fatty acids are an integral part of the structure
and function of the brain. The brain does not function well
unless adequate amounts of omega-3 fatty acids circulate in the
bloodstream and are incorporated into cell membranes. Omega-3
fatty acids also appear to influence the brain chemicals
involved in antidepressant action. For example, French
scientists have shown that rats deficient in omega-3 fatty
acids had more receptors for the neurotransmitter serotonin and
a corresponding decrease in dopamine in the frontal cortex. The
direction of the changes in these neurotransmitter systems is
consistent with some human models of major depression. Not
surprisingly, other scientists have observed that increasing
the dietary intake of omega-3 fatty acids boosted the levels of
the neurotransmitter dopamine in the frontal cortex of rats. In
humans, increased dopamine in the frontal cortex increases
drive and motivation, attributes lacking in the depressed
person.

Research on infants shows that DHA is essential for normal
brain development, thinking, and concentration in infants.
While breast-fed infants are smarter than formula-fed infants,
a study from the University of Dundee, United Kingdom, found
that term infants fed DHA-fortified formulas for the first four
months of life scored higher on problem-solving tests at ten
months of age.
Food & Mood by Elizabeth Somer MA RD, page

Some experts insist that omega-3 fatty acid may be the magic
intelligence-boosting ingredient in mother's milk. Omega-3s
have been found critical in fetal and infant brain development.
Food Your Miracle Medicine by Jean Carper, page
285
The human body converts Omega-3 fats into DHA—a nutrient that
is needed by all of us, and one that is especially critical for
the brain development of fetuses and newborns. There are,
however, indications that there can be a great deal of
variation among people in how efficiently their bodies convert
Omega-3 fats into DHA. For this reason, I strongly advise those
pregnant and nursing women who choose not to eat fish to be
certain to include ample amounts of supplementary DHA. Fatty
fish are high in DHA, which is good, but they are often high in
toxic metals and environmental contaminants that are
particularly damaging to babies.
Food Revolution by John Robbins, page 93
DHA is essential for the growth and functional development of
the fetal and infant brain and visual system. Human breast milk
contains DHA but, unless supplemented with DHA, infant formulas
in the U.S. do not contain any significant amounts. In Europe
and Japan, by contrast, infant formulas are routinely
supplemented with DHA.
PDR For Nutritional Supplements by Sheldon Saul Hendle
and David Rorvik, page 140
DHA is vital for normal brain development for the fetus and
infant and for the maintenance of normal brain function
throughout life. DHA appears to be a major determinant of
membrane fluidity in brain cells, and this could play a major
role in the maintenance of normal cognition and mood.
PDR For Nutritional Supplements by Sheldon Saul Hendle
and David Rorvik, page 148
Researchers have found that breast-fed babies have higher
intelligence than bottle-fed babies, probably because of the
omega-3 found in mother's milk. And it doesn't help just
babies. A study showed that older men who ate fish regularly
had better working brains than men who didn't eat fish.
Eat and Heal by the Editors of FC&A Medical
Publishing, page 164
While growing older is something we must all embrace, unless
brain cells have withered and died, the diminishment of our
mental abilities is not inevitable. The various causes of
mental decline can be reversed and the progression of
degenerative changes to the brain's neurons can be slowed.
"Losing control of your mental faculties as you age isn't
inevitable and can be reversed," says brain longevity expert
Dharma Singh Khalsa, M.D., author of brain Longevity. Even in
the late stages, Alzheimer's disease can be halted or at least
slowed down; catch it early enough and it can be reversed. And
if you deal with the possibility of brain decline at mid-life,
your chances of preventing it altogether are high.
Alternative Medicine by Burton Goldberg, page
325
Added support to the claim of essentiality is the observation
that large amounts of DHA have been found in the brain and
eyes. In one experiment, female monkeys were fed diets low in
DHA during pregnancy. Their offspring suffered from eye defects
until their diet was supplemented by DHA.
Saturated Fat May Save Your Life by Bruce Fife ND, page

DHA plays a particularly crucial role in the brain development
of infants and children. Together with other long-chain
polyunsaturated fatty acids, DHA accumulates in the fetal brain
late in pregnancy, and continues to accumulate during an
infant's first few months of life. Human breast milk contains
much more of these critical fats than cows’ milk or formula, so
babies who are not breastfed have lower levels of these
important nutrients. Researchers have determined that these
important fatty acids affect intelligence in infancy and
perhaps later in life.
The memory Solution by Dr Julian Whitaker, page
118
Omega-3 fatty acids are essential for the normal development of
the unborn baby's brain, especially during the final three
months of gestation when the size of its brain increases
threefold. If the mother fails to get enough of these nutrients
in her diet, the fetus will pirate what she has stored in her
tissues—including her brain. Lab tests show that new mothers
have half the normal blood levels of omega-3 fatty acids. Women
who breast-feed their babies have even lower levels of DHA
because they are continuing to supply the baby's need for
omega-3 fatty acids. If a woman does not replenish her store of
these essential elements following the birth of a child, she
will have lower and lower levels with each additional child.
Some people suggest this is why firstborn children score higher
on intelligence tests. Until now, people have attributed the
well-documented mental superiority of firstborn children to the
fact they spend more one-on-one time with a parent. It is now
being suggested that their greater cognitive abilities may also
be due to a more generous supply of maternal DHA.
The Omega Diet by Artemis P Simopoulos MD and Jo
Robinson, page 95
Evidence from the nursery suggests that they might. Human
breast milk contains DHA, but infant formulas do not. (U.S.
manufacturers of baby food are not yet required to add DHA to
their products.) As a result, breast-fed babies have more DHA
in their brains and retinas than bottle-fed babies. Breast-fed
babies also have better visual acuity than bottle-fed babies,
and, years later, score higher on standardized tests of
reading, visual interpretation, sentence completion, nonverbal
skills, and math. The superior performance of breast-fed babies
could be due to any number of factors, however, including the
fact that women who breast-feed their babies tend to be of a
higher socioeconomic class. But careful studies show that DHA
plays a key role in cognitive development.
The Omega Diet by Artemis P Simopoulos MD and Jo
Robinson, page 89
Most of the clinical data on omega-3 fatty acids involves fish
oil and its omega-3 components. Fish oil contains the two
primary long-chain omega-3 fatty acids, EPA and DHA. DHA is
generally incorporated into the cell membranes found throughout
the body, but it is found in highest concentration in the
retina, brain, and sperm. DHA is crucial for normal brain
development and optimal cognitive and visual functioning in the
fetus and newborn.
The Omega3 Connection by Andrew L Stoll MD, page
208
The studies have been somewhat mixed, but it appears that adult
humans cannot convert enough ALA to EPA and then to DHA.
Newborns appear to be better able to transform ALA to the
longer-chain omega-3s, but these conversions may still be
inadequate to fill the huge need of young children for omega-3
fatty acids. Thus, some nutritional scientists believe we must
consume the fish and fish oil-derived long-chain omega-3 s
directly for optimal brain health. Strict vegetarians likely
have lower levels of the long-chain omega-3 fatty acids, EPA
and DHA, than non-vegetarians, but may in the future be able to
purchase both EPA and DHA supplements derived directly from
algae.
The Omega3 Connection by Andrew L Stoll MD, page
46
DHA is critical for the proper development and function of the
brain because your brain cells need it to transmit electrical
impulses efficiently. It's not surprising, therefore, that a
DHA deficiency can lead to memory, behavior, and learning
problems.
Natural Physicians Healing Therapies by Mark Stengler
ND, page 176
Most people may be deficient in DHA because of ALA to DHA
conversion problems; DHA is found preformed in fresh sea
vegetables, in cold water salmon, cod, sardines, mackerel, in
fish oils. Its precursor is Alpha-Linolenic Acid (ALA),
composing 5 0-60% of Flaxseed oil, and 8-20% in unhydrogenated
Soy, Walnut, Pumpkin, and Hemp seed oils. The brain sends
messages to the body through the Central Nervous System,
composed of positively-charged atom salts of Calcium,
Magnesium, Potassium, and Sodium in the blood that keys either
Motor Nerves' muscular activity, or Sensory Nerves' pain
feedback, electrically via thousands of little cellular
batteries.
Anti-Aging Manual by Joseph B Marion, page

One type of omega-3 fatty acid is called docosahexaenoic acid
(DHA). DHA is found throughout the fatty tissue in our brains,
and it appears to play a role in how our brain functions. A
growing body of research has confirmed that infants who are
deficient in levels of this fatty acid have less than optimal
neurological function, especially intelligence. Furthermore, a
great number of neurological conditions, such as depression,
attention deficit disorder, and schizophrenia, also have a high
correlation with deficient levels of DHA in the bloodstream.
Researchers have found that patients with bipolar depression
often respond dramatically to very high dose supplementation
with oils rich in DHA.
The Okinawa Program by Bradley J Willcox MD Craig
Willcox PhD Makoto Suzuki MD, page 277
Studies show that essential fatty acids, the building blocks of
the brain and nervous system, are lacking in many MS patients.
Multiple sclerosis is most common in Western countries where
people consume large amounts of meat, dairy products, and
processed foods— all foods low in essential fatty acids—and is
least common in countries where diets are high in unsaturated
fats, including seed oils, olive oil, oily fish, fresh fruits,
and vegetables—all foods high in essential fatty acids. A
predominantly meat versus vegetarian diet seems to be a
significant risk factor.
Alternative Medicine by Burton Goldberg, page

The types of fat in your diet may influence your memory, moods,
response to stress, and learning ability. Your brain contains a
high percentage of fat. This is "structural" fat, the kind that
helps form your cell membranes and plays a vital role in how
your brain cells function. Your brain is unusually rich in the
omega-3 fatty acid DHA. Human breast milk contains DHA, but in
the United States and some other countries, infant formulas do
not. Breast-fed babies score higher on many types of
standardized tests than bottle-fed babies. DHA has improved
brain function in infants, adults, and the elderly.
The Omega Diet by Artemis P Simopoulos MD and Jo
Robinson, page 99
The brain is 60 percent fat and requires essential fatty acids,
especially DHA, to function properly. It has been shown that
people deficient in DHA are much more likely to suffer from
depression.
Natural Physicians Healing Therapies by Mark Stengler
ND, page 180
The Omega fatty acids play a prominent role in a person's
mental health. A number of mental disorders, including
schizophrenia and manic-depression, may very well be
manifestations of an Omega deficiency.
Omega 3 Oils by Donald Rudin MD and Clara Felix, page
209
Special fats found in fish oil, called the omega-3 fatty acids,
help regulate mood by increasing serotonin levels, the nerve
chemical that relieves depression. Low intake of fish oils
lowers brain levels of serotonin in animals and increases
aggressive and hostile behaviors. Similar effects have been
noted in humans with lower fish oil consumption and serotonin
levels, including increased rates of impulsive suicide
attempts, according to researchers at the National Institute of
Alcohol Abuse and Alcoholism in Bethesda, Maryland.
Food & Mood by Elizabeth Somer MA RD, page
186
Some experts believe fish fights depression because
neurotransmitters, the brain's Pony Express riders that carry
messages from cell to cell, have an easier time wriggling
through fat membranes made of fluid omega-3 than any other kind
of fat. This means your brain's important messages get
delivered.
Eat and Heal by the Editors of FC&A Medical
Publishing, page 146
Scientists don't know exactly how omega-3's protect against
depression, but they do know that the fats are important to
health of neurons, or brain cells. To get sufficient omega-3's
to battle depression, Dr. Zuess recommends taking approximately
10 grams a day of DHA and EPA, which usually amounts to about
30 fish-oil capsules daily. Take them in divided doses with
meals. This remedy is safe for long-term use.
Alternative Cures by Bill Gottlieb, page
191
Fatigue and depression often go hand in hand. To help a blue
mood, Dr. Schwartz suggests taking 1,000 milligrams of omega-3
fatty acids, which are essential for normal brain function.
Take the supplement every day at breakfast, she advises.
Alternative Cures by Bill Gottlieb, page
252
Dr. Andrew Stoll, a Harvard psychiatrist, found that fish oil
capsules helped people with bipolar disorder, or manic
depression, who go through periods of extreme highs and lows.
He says, "The striking difference in relapse rates and response
appeared to be highly clinically significant." Stoll suggests
the omega-3 fatty acid in fish oil may slow down neurons in
your brain, much like the drug Lithium, which is used to treat
manic depression.
Eat and Heal by the Editors of FC&A Medical
Publishing, page 146
Research conducted at Brigham and Women's Hospital in Boston
indicated that omega-3s block abnormal brain cell signaling in
patients who have bipolar disorder. Therefore, omega-3s can be
a powerful adjunct in treating this illness.
Bottom Line Yearbook 2004 by Bottom Line Personnel,
page 73
The point is that the origin of depression may be physical,
such as deficiency of omega-3 fatty acids, folate, or B12,
rather than mental. As another example, the bacteria in your
gut can affect your brain chemistry; these bacteria release
substances that can cause depression because they interfere
with the brain's neurotransmitters (the chemicals in our brain
that are involved with mood and thinking).
Ultraprevention by Mark Hyman MD and Mark Liponis MD,

Fish oil even helped migraine sufferers have fewer and less
severe headaches. And there is strong evidence that omega-3
fats can help with a host of mental illnesses including
depression, mood disorders, and even schizophrenia. Some
doctors even think the epidemic amounts of mental illness in
modern societies can be traced back to the omega imbalance in
the food supply.
Eat and Heal by the Editors of FC&A Medical
Publishing, page 164
Omega-3 fatty acids, which are lacking in most people's diets
in the United States, are abundantly present in the brain and
are essential for normal brain function. Though little is
currently known about how omega-3 fatty acids regulate mood,
recent findings show a correlation between low levels of these
compounds and depression.
Fight Back With Food by Readers Digest, page
73
Recent research at Harvard has shown that supplemental
essential fatty acids can improve the symptoms of bipolar
(manic-depressive) disorder. This is based on the fundamental
understanding that the cells of the brain normally contain high
levels of DHA, which is also commonly found in fish fat, and
that adequate levels of this type of fat are critical for
healthy communication between brain cells.
Ultraprevention by Mark Hyman MD and Mark Liponis MD,
page 13
Schizophrenia is a devastating mental disorder that tends to
strike early in adulthood. New antipsychotic drugs have helped
many schizophrenics function minimally in society, but they
have failed to relieve all of the troubling symptoms. Recently,
three independent groups of researchers have found that
schizophrenics have abnormally low levels of DHA. Prompted by
these findings, a fourth group treated twenty schizophrenic
patients with fish oil. The therapy was well tolerated and
relieved both types of symptoms commonly seen in
schizophrenics: "positive symptoms," such as delusions and
hallucinations, and "negative symptoms," such as social
withdrawal and lack of emotions. Some patients also got relief
from abnormal involuntary movements called "tardive
dyskinesia," which are a common side effect of prolonged drug
treatment. The investigators concluded that omega-3 fatty acids
present "novel and exciting therapeutic possibilities."
The Omega Diet by Artemis P Simopoulos MD and Jo
Robinson, page 98
Depression is linked with low blood levels of DHA. Alcohol
leaches DHA out of the brain. Between 16 and 50 percent of
alcoholics suffer from depression, as do up to 70 percent of
chronic, heavy drinkers. If a pregnant woman does not have
enough omega-3 fatty acids in her diet, the fetus will rob the
fatty acids from her tissues. If a woman has additional
children and does not replace the missing EFAs, a woman will
have lower levels of DHA with each subsequent child. A lack of
DHA has been linked with postpartum depression.
