Fish Oil: How Much Should I Take
Each Day? - Dr. Shannon
Margarine met omega 3 totaal
zinloos
Omega-3-vetzuren helpen hartpatiënt niet.
Unilever, die de vetzuren toevoegt aan het eigen margarinemerk Becel, is verrast over de
uitkomsten van een onderzoek.
Hoge inname van omega 6 vetzuur linolzuur
(zit in oa margarine) verstoort de opname van omega 3. Voor Unilever heeft de haan nu 3
keer gekraaid. Eerst jaren volhouden dat geharde vetten gezonder waren dan roomboter,
daarna hebben we het linolzuur sprookje gehad en nu de onzin van toegevoegde omega 3 aan
linolzuurrijke margarine. De beste bronnen van omega 3 blijven walnoten, lijnzaad, algen,
vette vis en rood vlees van dieren die zich voeden met gras.

Fish oil and your health: What are
fish oil's true benefits?
Much has been written about the benefits of
fish oil and and whether it can help prevent heart disease. A study published in the
Journal of the American College of Cardiology looked at a range of studies involving tens
of thousands of patients over a time span of 30 years. "This isn't just hype; we now
have tremendous and compelling evidence that demonstrates the protective benefits of fish
oil in multiple aspects of preventive cardiology," Dr. Carl Lavie, an author of the
study, writes. Although eating fatty fish is the preferred method of getting the
recommended dose of fish oil, supplements, in consultation with a physician, could also be
a source.
Omega-3 vetzuren stimuleren de
longfunctie tijdens sportactiviteiten
We hebben allemaal gehoord van de positieve
effecten van Omega-3 vetzuren op onze gezondheid. Omega-3 vetzuren kunnen mate van
depressiviteit verminderen, helpen in afvallen en goede hart- en cardiovasculaire
gezondheid, en hebben nog veel meer andere potentiele voordelen op korte termijn en bij
chronische aandoeningen/ziekten. Een van de meest recente onderzoeken betreffende omega-3
vetzuren heeft gevonden dat je longen positief gesimuleerd worden door omega-3 vetzuren,
vooral tijdens sportactiviteiten.
Jongeren die psychotisch dreigen te worden
kunnen met een kuur van 12 weken visolie geholpen worden. Dat blijkt uit een klinisch
onderzoek waarbij visolie vergeleken werd met placebo (nepolie) (Archives of General
Psychiatry februari 2010;67:146). Hoe is dat mogelijk?
Humane studie: visvetzuren
vertragen veroudering op moleculair niveau
Hoe meer visvetzuren er in je bloed zitten,
des te trager verouderen je cellen. Dat concluderen cardiologen van San Francisco General
Hospital in een studie die is verschenen in JAMA. De visvetzuren EPA en DHA maken dat de
telomeren in je DNA minder snel korter worden.

Het ene artikel na het andere verschijnt over de vermeende gezondheidsvoordelen van het
eten van vis en het gebruik van visoliecapsules. Dit terwijl wereldwijd door
wetenschappers gewezen wordt op de zeer ernstige achteruitgang van de visbestanden en op
het feit dat er uitstekende alternatieven zijn voor vis en visolie.
In a bad mood? Eat fish! Studies have shown
that foods containing Omega-3 Fatty Acids (like fish) can actually boost your spirits.
How? Researchers say that a particular type of Omega-3 Fatty Acid plays an important role
in brain development and function and could have an affect on our moods as well. So just
how much of the Omega-3s do you need to reap the benefits? Its recommended you eat at
least two servings of fatty fish a week. Also, taking a supplement can help as well. Learn
more in this video.
Veganisten en omega 3
Vandaag ontving ik dit mailtje van
Hallelujah Acres. Voorwaar: een wonder, hallelujah. Wat blijkt? Deze super veganisten die
heel hun dieet (massa's boeken, dvd's, recepten) hebben gebaseerd op een zin uit de Bijbel
zijn om......... Ze gaan aan de visolie!!!!!!!!! Lieve hemel Ron, dat wil nogal wat
zeggen! De reden is dat hun inzichten zijn vernieuwd en het isvolgens hun niet meer
mogelijk om de super kwaliteit voedsel uit Bijbelse dagen te halen. Dus hebben we
aanvulling nodig van visolie.
Het ene artikel na het andere verschijnt
over de vermeende gezondheidsvoordelen van het eten van vis en het gebruik van
visoliecapsules. Dit terwijl wereldwijd door wetenschappers gewezen wordt op de zeer
ernstige achteruitgang van de visbestanden en op het feit dat er uitstekende alternatieven
zijn voor vis en visolie. Overbevissing en bijvangst zijn uitgebreid gedocumenteerd. Ruim
40% van alle visvangst gaat dood of ernstig verminkt terug overboord - dit komt overeen
met meer dan 40 miljard kilo vis en andere zeedieren die hiervoor onnodig sterven. Toch
blijven gezondheidsinstanties zoals de WHO, vele artsen, maar ook politici, het consumeren
van vis en visolie aanmoedigen. Wetenschappers hebben berekend op basis van gegevens van
de laatste decennia, dat als we zo doorgaan is er in 2048 geen eetbare vis meer over is.
Visvetzuren remmen achteruitgang
lichamelijke prestaties door veroudering
Veroudering komt met minder gebreken als je
meer visvetzuren [wetenschappelijke term: n-3-vetzuren] in je bloed hebt. Tot die
conclusie komen geriaters van de Second University of Naples in een studie onder
dertienhonderd oudere Italianen. Visvetzuren remmen verouderingsprocessen in het
bewegingsapparaat.
In januari van dit jaar bracht de American
Heart Association bijna een verdriedubbeling aan in de omega 6 aanbeveling. Uit recente
onderzoeken blijkt dat het gecompliceerder ligt, het overmatig gebruik van omega 6
vetzuren kan namelijk juist ernstige gezondheidsproblemen veroorzaken
Fish oil supplements may help some cardiac patients while harming others, suggests a new
review of evidence compiled by St. Michael's Hospital and University of Toronto
researchers. In a systematic review of trials where patients with implantable cardioverter
defibrillators used fish oil supplements, Dr. David Jenkins and Dr. Paul Dorian found
significant differences among the trials, indicating fish oil may be beneficial to some
patients while having a negative impact on others.
Omega-3 doubly good for female
brain power, but omega-6 makes girls dimmer
Omega-3 fatty acids, found in fish oil, are twice as effective in improving test scores
for girls as boys, U.S. researchers have found. While this appears to confirm the theory
that fish is brain food, the researchers also found that omega-6, found primarily in
rapeseed, sunflower, palm, and soy oils, diminishes the power of the brain.
The results of a major review of published research that examined the relationship between
depression and level of omega-3 fatty acids in the diet suggest that omega-3 fatty acids
have antidepressant effects. However, the researchers point out that the quality of the
studies means it's still too soon to say definitively that omega-3s can treat depression
or bipolar disorder.
A dietary cocktail that includes a type of omega-3 fatty acid can improve memory and
learning in gerbils, according to the latest study from MIT researchers that points to a
possible beverage-based treatment for Alzheimer's and other brain diseases.
Wake Forest researchers say popular
fish contains potentially dangerous fatty acid combination
Farm-raised tilapia, one of the most highly consumed fish in America, has very low levels
of beneficial omega-3 fatty acids and, perhaps worse, very high levels of omega-6 fatty
acids, according to new research from Wake Forest University School of Medicine. The
researchers say the combination could be a potentially dangerous food source for some
patients with heart disease, arthritis, asthma and other allergic and auto-immune diseases
that are particularly vulnerable to an "exaggerated inflammatory response."
Inflammation is known to cause damage to blood vessels, the heart, lung and joint tissues,
skin, and the digestive tract. "In the United States, tilapia has shown the biggest
gains in popularity among seafood, and this trend is expected to continue as consumption
is projected to increase from 1.5 million tons in 2003 to 2.5 million tons by 2010,"
write the Wake Forest researchers in an article published this month in the Journal of the
American Dietetic Association. They say their research revealed that farm-raised tilapia,
as well as farmed catfish, "have several fatty acid characteristics that would
generally be considered by the scientific community as detrimental." Tilapia has
higher levels of potentially detrimental long-chain omega-6 fatty acids than
80-percent-lean hamburger, doughnuts and even pork bacon, the article says.
According to EU funded researchers,
taking fish oil supplements in late pregnancy might reduce the risk of children developing
asthma
In the context of European research on early nutritional programming, a team of
researchers has traced the children born from mothers who had taken part in a trial.
According to their work, the risk of developing asthma was reduced by 63% in those whose
mothers had been given fish oil supplements during the last trimester of their pregnancy.
This study is part of the EU funded EARNEST project with scientists from 38 institutions
in 16 European countries. It is published today in the American Journal of Clinical
Nutrition.
A series of studies, funded by the National Institutes of Health, revealed that when
omega-3s were added to the diets of preemies, their visual development was the same as
that of a breast-fed infant's.
Omega-3 fatty acids protect against
Parkinson's, study says
Omega-3 fatty acids protect the brain against Parkinson's disease, according to a study by
Université Laval researchers published in the online edition of the FASEB Journal. This
study is the first to demonstrate the protective effect of a diet rich in omega-3 fatty
acids against Parkinson's.
Omega-3-Rich Fish Oils Reduce
Weight Gain in Animal Study
A diet that contains fish oil rich in omega-3 fatty acids may help the body metabolize fat
better and thereby gain less weight, according to a study conducted by researchers from
the Kao Corporation in Tochigi, Japan, and published in the Journal of Nutrition.
Scientists suspect omega-3 fatty
acids could slow acute wound healing
A recent study shows that popular fish oil supplements have an effect on the healing
process of small, acute wounds in human skin. But whether that effect is detrimental, as
researchers initially suspected, remains a mystery. The omega-3 fatty acids found in fish
oils are widely considered to benefit cardiovascular health and other diseases related to
chronic inflammation because of their anti-inflammatory properties. But insufficient
inflammation during the initial stage of wound healing may delay the advancement of later
stages.
Despite high levels of smoking, Japanese men are far less likely to have dangerous plaque
build-up in their blood vessels than white or Japanese-American men, a difference that
researchers believe stems from a lifelong, near-daily consumption of fish.
Utah Diabetes Center Studying
Whether Omega-3 Fatty Acid Can Prevent Type 1 Diabetes in Newborn Babies
The Utah Diabetes Center at University Health Care is screening pregnant women in their
third trimester and infants up to 5 months old for a study testing whether an omega-3
fatty acid found in some foods can prevent Type 1 diabetes. The Utah Diabetes Center is
one of nine centers nationwide participating in the Nutritional Intervention to Prevent
Type 1 Diabetes Pilot Trial, or NIP for short. The goal is to intervene in the disease
process before it begins in those babies most likely to acquire Type 1 diabetes later in
life. Babies in utero and up to 5 months old whose mother, father, brother, sister,
half-sister or half-brother has Type 1 diabetes are eligible for the study. Screening
consists of a simple blood test. Babies who qualify will receive free testing and medical
monitoring by diabetes researchers.
UCLA researchers report that omega-3 fatty acid docosahexaenoic acid, found in fish oil,
increases the production of LR11, a protein that is found at reduced levels in Alzheimer's
patients and which is known to destroy the the "plaques" associated with the
disease.
Studies on rodents and people suggest a diet rich in DHA, an omega-3 fatty acid found in
fish oil, helps delay or prevent Alzheimer's disease. Now University of California, Los
Angeles researchers have come up with a possible explanation.
Cancer as well as heart disease can be prevented by taking a ratio of at least 1:1 up to
2.5:1 unadulterated parent omega-6 to omega-3 essential fatty acids plus specific vitamins
and minerals.
A little wine boosts omega-3 in the
body - Researchers find a novel mechanism for a healthier heart
Moderate alcohol intake is associated with higher levels of omega-3 fatty acids in plasma
and red blood cells. This is the major finding of the European study IMMIDIET that will be
published in the January issue of the American Journal of Clinical Nutrition, an official
publication of the American Society for Nutrition and is already available on line
(www.ajcn.org ). The study suggests that wine does better than other alcoholic drinks.
This effect could be ascribed to compounds other than alcohol itself, representing a key
to understand the mechanism lying behind the heart protection observed in moderate wine
drinkers. The IMMIDIET study examined 1,604 citizens from three geographical areas -
south-west London in England, Limburg in Belgium and Abruzzo in Italy. Thanks to a close
cooperation with General Practitioners of these areas, all participants underwent a
comprehensive medical examination, including a one year recall food frequency
questionnaire to assess their dietary intake, alcohol consumption included. Omega-3 fatty
acids, mainly derived from fish, are considered as protective against coronary heart
disease and sudden cardiac death, thus their high blood concentration is definitely good
for our health.
