Omega-3 vetzuren tegen ADHD.*
Uit een studie blijkt dat verbetering van de verhouding tussen omega-6 en omega-3 vetzuren ten voordele van de omega-3 vetzuren bij kinderen met ADHD flinke verbeteringen geeft, zonder enige bijwerking. In de studie kregen kinderen van 6-17 jaar gedurende 8 weken dagelijks supplementen met wel 8 tot 16 gram omega-3 vetzuren, zowel
EPA als DHA. Dit zijn hoge hoeveelheden maar al uit eerdere studies was gebleken dat kinderen met ADHD een veel te hoge verhouding aan omega-6/omega-3 vetzuur in het bloed hebben.
Study Suggests High-Dose Fish Oil May Significantly Improve Behavior In Children With ADHD
The results of a pilot study published in the Nutrition Journal suggest that children with attention deficit hyperactivity disorder (ADHD) can benefit from daily supplementation of high levels of purified fish oils. The eight-week study demonstrated that children who consumed between 8 and 16 grams per day of EPA and DHA (the long chain omega-3 fatty acids found in fish oil) showed significant improvements in their behavior rated by both their parents and the psychiatrist working with
them.
The study monitored the ratio of two fatty acids in the blood: arachidonic acid (AA) and eicosapentaenoic acid (EPA). It has been known from previous studies that children with ADHD have a high AA/EPA ratio in the blood compared to control children. The amount of purified fish oil for each child was adjusted until his or her AA/EPA ratio reached ideal
levels.
The study found a statistically significant improvement in inattention, hyperactivity, oppositional/defiant behavior and conduct disorders as the AA/EPA ratio in the blood was lowered. The findings were true for children taking their optimal dosage of drugs to manage their ADHD as well for the children who had voluntarily stopped taking their drugs during the study.
"This is an important study as it indicates when adequate levels of fish oil are added to the diet, significant behavioral changes can occur. This study also indicates that the growing epidemic of ADHD may have a strong nutritional component-the lack of sufficient intake of omega-3 fatty acids, such as EPA and DHA," said Dr. Barry Sears, one of the co-authors of the study. "Equally important is that supplementation with high-dose fish oil is synergistic with existing drugs, giving both the physician and parent new dietary approaches toward correcting this growing epidemic in our children."
About ADHD
ADHD is a neurological condition characterized by the inability to concentrate in a sustained manner, to pay attention to tasks, and to control impulsive actions. It is estimated that 3 to 7 percent of children have this disorder. For 60-80 percent of children with ADHD, the condition continues into
adulthood. De volledige studie
