Children with poor behaviour control and reading skills had lower omega-3 levels.
By now, most people know that developing brains and eyes need the long-chain omega-3 fatty acid known as DNA.
The most critical period for DHA’s impact on brain development occurs before birth, when the fetus gets this brainy omega-3 via the umbilical cord.
But a series of clinical studies from Britain’s University of Oxford suggest that young children continue to gain brain benefits from dietary DNA … whether from fish or supplements.
Now, another study from Oxford adds weight to the idea that omega-3s keep helping kids’ brains, well into childhood.
The new study focused on schoolchildren with below-average reading ability, and compared their omega-3 blood levels to standard measures of cognition (reading ability and memory), behaviour, and emotional health.
And the UK team’s results affirm prior indications that omega-3 DHA blood levels can affect cognition and behaviour in schoolchildren.
Many of the best studies came from Oxford University’s Centre for Evidence-Based Intervention (CEBI), and most of those were led by Alex Richardson, Ph.D. … with psychiatrist Joseph Hibbeln, M.D. of the U.S. NIH playing a key role.
Three years ago, they covered the outcomes of an earlier study conducted by scientists from Oxford’s CEBI.
UK study affirms the value of omega-3s to younger schoolchildren.
The CEBI researchers examined blood from 493 children aged 7 to 9 years, all of whom had below average reading performance.
They tested the kid’s blood to determine its proportions of the two key omega-3s, DHA and EPA. (Of the two, DHA is much more important to brain function, while EPA appears to contribute to healthy behaviour control.)
The current medical consensus holds that a minimum percent of the fatty acids in human red blood cells should be omega-3s, in order to enable and promote optimal cardiovascular and heart health.
This measure is called the “omega-3 index”, and physicians increasingly view 8% as the minimum proportion of omega-3s needed in red blood cells to enable optimal heart, brain, and overall health, with 12% being optimal.
Reading ability, “working” memory capacity, behaviour control (ADHD-type symptoms), and emotional stability were also assessed in the 493 participating children, using standard tests.
The test results were adjusted to account for the impacts of factors known to affect learning and behaviour, such as household income, gender, consumption of fish and omega-3s, and use of medications for ADHD or other condition.
The UK team compared the children’s omega-3 levels to their learning and behaviour scores, with dismaying results:
* Lower DHA levels were linked to poorer reading ability and working memory performance.
* Lower DHA levels were linked to higher levels of oppositional behaviour and emotional lability.
* Omega-3 DHA and EPA levels were only 1.9% and 0.55% of total blood fatty acids, respectively, with DHA showing more individual variation.
As the authors wrote, “In these health UK children with below average reading ability, concentrations of DHA and other Omega-3s were low … and directly related to measures of cognition and behaviour. These … suggest the benefits from dietary supplementation with omega-3s (previously) found for ADHD, dyspraxis, dyslexia, and related conditions might extend to the general school population.”
While noted the need for controlled clinical trials to confirm the connection, they’ve already conducted one such study (“Slow-Reading Kids Aided by Omega-3s”), and they urged parents to ensure that kids get enough omega-3s: “… meanwhile, the low blood omega-3 status found across this sample would indicate that an increased dietary intake might be beneficial on general health grounds.”
The very low omega-3 levels found in the new CEBI study was disturbingly low, given that DHA is critical for normal brain and nervous system development.
In fact, it seems sadly unsurprising that children so sorely lacking in omega-3s would under-perform in school and suffer behavioural and emotional problems.
There is much research available on this subject but I believe all you parents, grandparents, and family friends have an obligation to make sure everyone reads this material.
And when you’re purchasing Omega-3s, make sure that they are organic. If you’re unsure of how and what to buy, just let me know and I’ll turn you on the natural, bioidentical supplements.
