View Full Version : Omega 3 improves learning and decreases mental disorders in growing children? (mods?)

The following is taken from Dr. Mercola's website. I'm not a regular reader there as I know he isn't a particularly trusted source for bodybuilding. However this quote has to do with enhanced learning and lower incidence of mental disorders in children fed omega 3 as they grow up.

http://www.mercola.com/beef/adhd.htm

"Imagine your brain conducting some routine maintenance on your dopamine and serotonin receptors (implicated in both ADD and mood disorders). These receptors are composed of an Omega-3 fatty acid called DHA.

If you don't have much DHA in your blood, man-made trans-fat molecules may be used as a construction material instead. But trans-fats (hydrogenated oils) are shaped differently than DHA: they are straight while DHA is curved.

The dopamine receptor becomes deformed and doesn't work very well. Repeat this scenario day after day, year after year, and you could wind up with problems like depression and problems concentrating. This problem is most severe for a child whose brain is still developing.

A lack of highly unsaturated fats is particularly noticeable in connection with brain and nerve functioning. An adjustment in diet to one with oil and protein contents high in unsaturated fats brings the best results in children.

Now imagine a child in school learning math. The act of learning requires the brain to form new neural pathways. DHA is needed, especially for the delicate neural synapses which are composed entirely of DHA. This child, like the vast majority of U.S. children, eats almost no Omega-3 fatty acids. What does the brain do?

Again, it struggles and finally uses other types of fats, which are the wrong shape. The neural network develops slowly and is defective. The child has learning and memory problems as well as behavior problems.

In a study of learning ability, rats were raised on either a diet that was deficient in Omega-3 fatty acids or one that was nutritionally complete. Initially, both groups of rats had similar numbers of synaptic vesicles.

After a month-long learning program, however, the Omega-3 enriched rats had considerably more vesicles in their nerve endings and also performed markedly better on the tests. This study suggests there may be a direct connection between the amount Omega-3 fatty acids in your diet, the number of synaptic vesicles in your neurons, and your ability to learn."

I know that omega 3 has a multitude of nutritional benefits, but I was unaware it had any mental effects. I am interested in knowing wether this information is true, because if so, it would be extremely persuasive in getting many people I know to feed their children some omega 3s on a regular basis.

Yes, cognitive benefits are among those from DHA/EPA. Do a quick search of pubmed and you will find a few meta analysis studies in it.

Omega-3 fatty acids are also a regular constituent of breast milk almost regardless if the mother takes in any so that goes to show you how important it is to development.

I also read this in the book Protien for life plan

Like you said, Grim, I would not read Mercola...at all actually. /forum/images/graemlins/tongue.gif

But yes, evidence seems to suggest that omega 3 fatty acids do assist cognitive function. Here is a quote from my article:

Nervous system

N3s are high in biologic structures which require fast movement, like transport mechanisms in the brain and retina. Due to this, it appears that omega-3s may have functions with the nervous system benefiting vision and the brain, among others. [49]

A study investigated if dietary manipulation of linolenic acid (omege 3) could provoke changes in DHA or DPA levels in the brain of pigs. Pigs were fed a solution containing linoleic acid (omega 6) with .7% or 3.9% linolenic acid solution, and no DHA or DPA. Results found that the highest linolenic acid group had the highest level of EPA and DHA in the brain and lower levels of omega 6's. Similar results have been seen when examining retinas. Other studies have found that human infants fed a formula lacking in omega 3's have lower levels of them in the brain.

These studies are not direct evidence of the benefits of omega 3's for cognitive function. But their prevalence in these areas does support the hypothesis.

Smooth cover up, haha. /forum/images/graemlins/grin.gif It's all good, Grim. /forum/images/graemlins/wink.gif
