Titolo: Re: integratori Omega-3 eliminano rapidamente nei bambini l'ADD & l'ADHD .

 prevenire o trattare la depressione
Riporto da una notizia della Mental Health Foundation britannica, di un 
annetto fa, che sottolineava il ruolo della dieta nei disturbi 
psichiatrici, e anche degli acidi grassi essenziali nell'Attention 
Deficit Hyperactivity Disorder.
 The Mental Health Foundation said yesterday that studies had clearly
 linked attention deficit disorder, depression, Alzheimer's disease and
 schizophrenia to junk food and the absence of essential fats, vitamins
 and minerals in industrialised diets.

The role of diet in relation to specific mental health problems
Depression
A number of cross-country and population-based studies have linked
the intake of certain nutrients with the reported prevalence of
diferent types of depression. For example, correlations between low
intakes of fish by country and high levels of depression among its
citizens - and the reverse - have been shown for many types of
depression.
Complex carbohydrates as well as certain food components such as
folic acid, omega-3 fatty acids, selenium and tryptophan are thought
to decrease the symptoms of depression. Those with low intakes of
folate, or folic acid, have been found to be significantly more likely
to be diagnosed with depression than those with higher intakes.
Similar conclusions have been drawn from studies looking at the
association of depression with low levels of zinc and vitamins B1, B2
and C. In other studies standard treatments have been supplemented
with these micro-nutrients resulting in greater relief of symptoms
in people with depression and bi-polar affective disorder, in some
cases by as much as 50%.
One way that vitamins and minerals may improve mental health and
cognitive function is through their role in the brain's conversion of
amino acids. much has been said in public fora about the importance
of the neurotransmitter serotonin, and its presence in lower levels
being linked to depression. Because of this, the precursor to
serotonin - the amino acid tryptophan - has been the focus of much
research. some studies have found that combining tryptophan with
selective serotonin reuptake inhibitor (SSRI) antidepressants gives
better results than SSRIs alone. Other dietary alterations can ease
or hinder the entry of tryptophan to the brain.
Schizophrenia
Studies have looked at the impact of specific nutrients on the rates
of schizophrenia in the general population, focusing on fats and
antioxidants. Epidemiological evidence has shown that people with
schizophrenia have lower levels of polyunsaturated fatty acids in
their bodies than those with no experience of the illness. Other
research has shown that antioxidant enzymes are lower in the brains
of people with schizophrenia.
Further work is needed in this area to identify specific mechanisms
through which diet can work alongside other care options to alleviate
the symptoms of schizophrenia.
Alzheimer's Disease
Specific connections have been found between the occurrence of
Alzheimer's and diferent intakes of foods, including saturated fat,
vitamins and minerals. Although there have been few controlled
clinical trials testing the efects of nutritional treatments, most
evidence points to the role of nutrition in the prevention of, rather
than the treatment of Alzheimer's disease. Many of the studies have
shown a positive association between saturated fat intake and the
incidence of dementia, and a negative relationship between the
incidence of dementia and intake of polyunsaturated fatty acid. One
study looking at the total fat intake of eleven countries found a
correlation between higher levels of fat consumption and higher
levels of Alzheimer's disease amongst over 65's.
Other studies have explored the protection from Alzheimer's that has
been linked with high vegetable consumption. one long term
population-based study found that high intakes of vitamins c and e
were linked to a lower risk of Ad, particularly among smokers, and
this finding has been replicated in other studies.
Attention Deicit Hyperactivity Disorder (ADHD)
Many parents, teachers and others have reported great improvements
when dietary changes are introduced to children with AdHd. Two food
groups that have been implicated through clinical research are
essential fatty acids (EFAs) and minerals. Studies have found some
EFAs to be signiicantly low in hyperactive children. A similar
relationship has been found with levels of iron in children with
symptoms of ADHD.

Mental health
* Some nutrients trick the brain by triggering an over-release of
neurotransmitters and some foods damage the brain by releasing toxins
or oxidants that harm healthy brain cells. There are many more
nutrients that serve the brain without deception or damage, which can
improve mood and mental well being.
* A balanced mood and feelings of well being can be protected by
ensuring that our diet provides adequate amounts of complex
carbohydrates, essential fats, amino acids, vitamins and minerals and
water.
* There is a plethora of anecdotal, clinical and controlled studies
that point to the importance of diet as one part of the jigsaw in the
prevention of poor mental health and the promotion of good mental
health.
* Research indicates that good nutritional intake may be linked to
academic success. A number of studies report that providing children
with breakfast improves their daily and long-term academic
performance.
* Among some young ofenders, diets supplemented with vitamins,
minerals and essential fatty acids have resulted in significant and
remarkable reductions in anti-social behaviour.
Mental health problems
* There is growing evidence that diet plays an important contributory
role in specific mental health problems including Attention deficit
Hyperactivity disorder (AdHd), depression, schizophrenia and
Alzheimer's disease.
* The presentation of depression in the UK population has increased
dramatically over recent decades and this has been accompanied by a
decrease in the age of onset, with more cases being reported in
children, adolescents and young adults.
* A correlation between low intakes of fish by a country and high
levels of depression amongst its citizens, as well as the reverse,
has been shown for major depression, post-natal depression, seasonal
affective disorder and bipolar affective disorder.
* The incidence of schizophrenia is similar across the globe,
although there are differences in outcomes between countries. This
implies that environmental factors have some role in determining the
duration and severity of symptoms, and the role that diet has to play
is attracting increasing scientific interest.
* Alzheimer's disease has become more common in the past fifty years
and is believed to be the result of a combination of factors,
including the aging population, genetics and environmental factors.
* growing epidemiological evidence suggests that diet may be one of
those environmental factors with associations being reported between
the occurrence of Alzheimer's and the amount of saturated fats,
vitamins and minerals consumed.
* complementary mental health care services that focus on diet and
nutrition report promising results, particularly among those who
experience ADHD and depression. On the whole however, they are poorly
resourced and have received insufficient research attention to draw
firm conclusions.

Se e' un falso disturbo che cosa perdi tempo a postare articoli che 
dimostrano che e' curabile con omega 3 ?
Se non esiste non serve neanche una cura !
andrea 

 parlare di cure nutrizionali per le malattie
e dice pure...
che gli omega 3 sono un integratore "naturale" e facilmente ottenibile......
gli omega 3 hanno un costo esorbitante rispetto gli eventuali vantaggi,
assai più dei farmaci.
Tanto è vero che gli "integratori" a base di omega 3 sono tutti "tagliati" e
per assumerne un quantitativo sufficiente ad avere qualche effetto (per es
per le emicranie) bisognerebbe farsene a kili......ovviamente ad un prezzo
esagerato.......
questo è un semplice copiaincolla senza nessuna considerazione critica......

 esagerato.......
Alcuni studi che ho letto sugli effetti degli omega 3 sui disturbi 
psichiatrici danno risultati diversi, controversi anche sui dosaggi. 
Alcuni però sostengono che bastino dosi non esagerate :)
"Omega-3 Fatty Acid intake helped with the irritability component of 
patients suffering from bipolar disorder with a significant presenting 
sign of irritability. Low dose (1 to 2 grams per day), add-on O-3FA may 
also help with the irritability component of different clinical 
conditions, such as schizophrenia, borderline personality disorder and 
other psychiatric conditions with a common presenting sign of 
irritability".
