Essential Fatty Acids & Learning Disorders
Tuesday, April 4th 2006
What are polyunsaturated fatty acids?
Fatty acids can be grouped into a few main categories having distinguishing features. For example, saturated fatty acids tend to be solid at room temperature so we find lots of them in foods like butter, lard and beef tallow. Polyunsaturated fatty acids are liquid at room temperature and are the main constituents of food oils like soybean, corn, sesame, evening primrose and fish. Polyunsaturated fatty acids are often called "good fats" because eating them can improve health.
What are essential fatty acids (EFAs)?
Polyunsaturated fatty acids are further subdivided into two main categories called omega-6 and omega-3. These two families can be created within our bodies starting with parent essential fatty acids (EFAs) through a multi-step process that is very slow in humans. The parent EFAs are called "essential" because our bodies cannot make them and so we must eat them everyday - just like vitamins and minerals. Fatty acids made from these parent EFAs are collectively called long chain polyunsaturated fatty acids (LCPs). It is these LCPs, not the parent EFAs that have the most impact on our health.
Are LCPs important for brain function?
Omega-3 docosahexaenoic acid (DHA) and omega-6 arachidonic acid (AA) are the most abundant LCPs in the brain. These LCPs are critical for proper brain, nervous system and eye development and function. Another omega-3 LCP, eicosapentaenoic acid (EPA), is primarily important for circulation and helps deliver nutrients to the brain. It is also a minor component of the brain and it helps AA transmit messages between nerves. Unfortunately, our modern diets have too little of these vital nutrients because we eat mostly EFA containing vegetable oils instead of LCP rich foods like eggs, organ meats and fish. The British Nutrition Foundation recommends that we eat at least 1g of EPA + DHA per day!
How are LCPs involved in learning disorders?
Population studies show that adults and children with attention deficit hyperactivity disorder (ADHD) and dyslexia, and children with maladjusted behaviour, autism and hyperactivity have lower than normal body levels of DHA and AA, or they have physical signs of LCP deficiency including dry skin, hair and nails, and frequent thirst and urination. These low levels are more than just a dietary deficiency and likely result from an inability to internally convert dietary EFAs into LCPs.
Can LCP Supplementation help?
Clinical studies published in peer reviewed scientific journals involving more than 200 children confirmed that LCP supplementation is an effective way to relieve some symptoms of learning disorders.
How LCP helps children learn in school
· can remember longer sequences of instruction
· more able to focus on defined tasks
· less likely to be disruptive
· more able to read and understand text and so require less assistance
· writing is physically easier and so they are more likely to do it
· are more creative
· self esteem improves
Efalex supplementation helped:
Results were highly significant because children were already being treated with conventional drugs. Improvements on Efalex were beyond those achieved with drug therapy.
Children with specific learning difficulties
· reduce anxiousness, shyness and hyperactivity
· improve reading skills
Children with ADHD symptoms
· reduce hyperactivity by 73%
· improve attention by 64%, conduct by 69%
· oppositional defiance by 75%
Children with neurodevelopmental disorders
· reduce excitability
· improve memory and concentration
· improve reading ability
· improve co-ordination
