Outline
• Vitamins and Minerals
• Amino Acids
• Essential Fatty Acids
Basics of NutritionThe essential major components of human nutrition
are:• water• carbohydrates (for fuel)• vitamins and minerals• amino acids (from protein)• essential fatty acidsA deficiency of any of these results in disease, or
even death in extreme cases
Examples of Nutritional Deficiencies
• Lack of vitamin C -> scurvy• Lack of iron -> anemia; mental retardation in
children• Lack of calcium or vitamin D -> rickets
Children with autism are not classically deficient, but most are low in some essential vitamins, minerals, amino acids, and fatty acids .
“Children with Starving Brains” by J. McCandless
Why consider vitamin/mineral supplements for people with autism?
1) vitamin/mineral deficiencies common in general population
2) often restricted diets (“picky eaters”) -> limited vitamin/mineral intake
3) poor digestion (25% have chronic diarrhea, 25% chronic constipation);
Endoscopies by Wakefield, Buie, Krigsman show damage to gut -> limited absorption of nutrients?
4) Rosseneu, Shaw research: overgrowth of harmful bacteria in GI tract:
fewer “good” bacteria which actually produce several vitamins
5) 18 studies demonstrated benefits of vitamin B6/Mg
6) 1 study showed vitamin C was beneficial in autism
7) Prof. Megson: cod liver oil (with high levels of vitamin A, D, and essential fatty acids) helped with gaze aversion, behavior
8) Dr. Rimland’s set of parent-reported case studies on benefits of vitamins/minerals
Goals: 1) Evaluate nutritional status of unsupplemented children with ASD vs. unsupplemented typical children, age and gender matched.2) Check for correlations of symptoms of autism with nutritional levels
Participants:Enrolled: 48 ASD, 35 controlsAge: 3-9 yearsAll children from Arizona.No use of vitamin/mineral supplements in 2 months prior to sample collection.

Why do children with autism benefit from vitamins if levels not very different from typical children?
1) Typical children do not eat 5 servings of fresh fruit and vegetables each day, so the level of vitamins in typical children is not optimal.
2) Several studies show children with autism are under increased oxidative stress, suggesting a need for increased levels of antioxidants.
Vitamin B6 and Magnesium• Over 20 studies, including 11 double-blind,
placebo-controlled studies, found that high dose vitamin B6 (8 mg/pound bodyweight) with Magnesium (3-4 mg/pound bodyweight) resulted in wide range of behavioral improvements
• Only 2 negative studies: one with very few subjects, and one with half dose
• Overall, very safe, and helps 50% of children and adults.

Summary re. Vitamin B6
Some children and adults with autism benefit from high-dose B6, to make neurotransmitters, glutathione, and many other important substances
Simple measurement of kryptopyroles in urine determines if high-dose vitamin B6 (or zinc) is needed (caution – destroyed by light, so collect in dark).
Doses up to 10-15 mg/kg may be needed (1000 mg max); takes about 6 months to lower kryptopyroles in urine
Always give at least half as much magnesium (400 mg max).
Vitamin B12• Methyl cobalamin (methyl form of vitamin B12) is
most active form of vitamin B12• Vitamin B12 is very hard for body to absorb orally• Injectable form of methyl-B12 may help up to 70% of
autistics per informal reports by Dr. Jim Neubrander, at doses of 75 mcg/kg bodyweight, 2x/week, for 6+ weeks
• Safe, but needs research to verify effectiveness• Research by Prof. Richard Deth shows it is needed to
produce glutathione, and to help Dopamine 4 receptor function (important for attention)
Low Cysteine and Glutathione
• Studies by Jill James and Tapan Audhya find low cysteine and extremely low glutathione in children with autism; glutathione is important antioxidant and for detoxification
• Treatment study by Jill James finds that 800 mcg of folinic acid and 1000 mcg of TMG over 8 weeks improve cysteine and glutathione levels somewhat
• Addition of 75 mcg/kg of methyl B12 injections helps more
• Informal reports of improvement in behavior

Lithium – previous ASU study
The only abnormality in mothers of children with ASD was low levels of lithium:all ages: -40%, p=0.05mothers of children ages 3-8: -56%, p=0.005 (highly
significant!)
Similarly, children with ASD had lower levels of lithiumall ages: -15%, not significantages 3-6 yr: -30%, p=0.04
Importance of Lithium• Hair is a reliable measure of lithium• Lithium is probably an essential mineral (not well studied)• Study of goats on lithium-deficient diet found:
– decreased activity of monoamino oxidase, which is of particular importance to manic-depression, chronic schizophrenia, and unipolar depression.
– lowered immunological status, and suffered from more chronic infections (may explain why children with autism had more ear infections)
• Lithium concentrations highest during first trimester, and highest in the brain, so a deficiency of it could affect early fetal development, including early brain development
Lithium - continuedSeveral studies have show low lithium correlates with:• schizophrenia• neurosis• suicide• behavior problems• crime (homicide, rape, burglary, theft, drug use, juvenile runaways)
Finally, a four-week placebo-controlled study of 24 former drug users found that 400 mcg/day of lithium resulted in steady increases in mood scores, especially in subcategories reflecting happiness, friendliness, and energy.
Lithium• Not included in most nutritional supplements, or in prenatal
supplements• An estimated RDA is 1000 mcg/day, and people in the US
consume only about 500 mcg/day• Extremely high doses of lithium (1,000,000 mcg/day) are used as
a psychiatric medication, primarily for “calming/mood stabilization”, especially for bipolar disorder; nearly toxic at that dose
• RECOMMENDATION: a dosage of 200-1000 mcg/day should be safe, and may be beneficial to younger children with autism and their mothers
• More research needed
Essential Minerals - Iodine• Iodine: 45% lower in ASD than controls, p=0.005 (highly
significant!)• in 3-6 yr old group, similar value (-47%)
• Caution: no data showing that iodine in hair correlates with level in body (blood is standard measurement)
• iodine is an essential mineral• major role of iodine in body is in thyroid function• a deficiency of iodine causes goiter (enlarged thyroid) and
mental retardation (Cretinism)• worldwide, the leading cause of mental retardation is iodine
deficiency, affecting roughly 20 million children
Iodine - continued
• In early 1900’s, iodine deficiency was up to 30% in some parts of the US
• iodine in salt is believed to be sufficient to make iodine deficiency very rare in the US/western world
• however, iodine levels in blood have declined 50% from 1970’s to 1990’s per NHANES I and III, possibly due to decreased salt intake
• many fast foods (fries, chips) use non-iodinized salt• CAUTION: too much iodine can also decrease thyroid function• RECOMMENDATION: measure iodine in blood, supplement
at modest level if low

Amino Acids
• Protein is composed of long strands of many amino acids
• The body needs to digest protein to small peptides or individual amino acids
• Amino acids can be measured in plasma (fasting) or urine (24-hr best)
• Caution – high level in urine sometimes indicates wasting, resulting in low levels in body
Essential Amino Acids in Urine
• Lysine high and possibly significant;• Methionine slightly low but not significant;• Histidine slightly high but not significantNote: high level in urine may mean low level in body

Summary of Amino Acids
• Some children with autism have low levels of amino acids in body
• Recommendation: measure levels, and supplement if low
• Also, consider measuring neurotransmitter levels in platelets, and then supplement with precursors if low (neurotransmitters made from amino acids) – more research needed
Essential Fatty AcidsEssential Fatty Acids are termed “essential” because they are
necessary for human life.The major types of essential fatty acids are Omega-3 and
Omega-6.Ancient human diets contained a roughly 1:1 ratio of Omega-3
to Omega-6 fatty acids.However, since Omega-3 fatty acids spoil much faster than
Omega-6, commercial food processors usually remove them or “hydrogenate” them to increase shelf life.
Today, American diets contain a roughly 1:15 ratio of Omega 3 to Omega-6; in other words, most people in the US are very low in Omega 3 fatty acids.
EFA’s in Autism
A recent study in France found that children with autism had normal levels of Omega-6, but their levels of Omega-3 were 25% below “normal”, and even “normal” is probably far from “optimal”.
A small preliminary study by Gordon Bell (Un. Stirling) of 7 children with ASD also found less EPA and DHA, and sometimes more arachidonic acid, than control subjects.
Sources of Omega-3 Fatty Acids
In human diets, the major source of omega-3 fatty acids is fish. Fish contain two important types of Omega-3 fatty acids, EPA and DHA.
Some fish contain much more omega-3’s than others.
Importance of EPA and DHA
EPA is important in reducing inflammation (such as in the GI tracts of children with autism).
DHA is critical to brain development, and 20% of an infant’s brain is made of DHA.
Both are critical to all cell membranes in the body; they regulate nutrients going into the cell, and waste leaving the cell.
They also affect the release and reuptake of neurotransmitters.

BACKGROUND: There is increasing evidence that fatty acid deficiencies or imbalances may contribute to childhood neurodevelopmental disorders. METHODS: We conducted a randomized, double-blind, placebo-controlled 6-week pilot trial investigating the effects of 1.5 g/d of omega-3 fatty acids (.84 g/d eicosapentaenoic acid, .7 g/d docosahexaenoic acid) supplementation in 13 children (aged 5 to 17 years) with autistic disorders accompanied by severe tantrums, aggression, or self-injurious behavior. The outcome measure was the Aberrant Behavior Checklist (ABC) at 6 weeks. RESULTS: We observed an advantage of omega-3 fatty acids compared with placebo for hyperactivity and stereotypy, each with a large effect size. Repeated-measures ANOVA indicated a trend toward superiority of omega-3 fatty acids over placebo for hyperactivity. No clinically relevant adverse effects were elicited in either group. CONCLUSIONS: The results of this study provide preliminary evidence that omega-3 fatty acids may be an effective treatment for children with autism.
Conclusion• Most autistic children have low level of ω3 fatty
acids.• Some autistic children have high level of ω6 fatty
acid.• The ratio of ω3/ω6 can be altered by administration of
ω3 & ω6 fatty acid (4:1 ratio) for 9 -10 months.• Younger children need a ratio higher in DHA (for
growth of neurons), and older children/adults need more EPA
Recommendation
• Measure EFA levels in RBC membranes, especially if GI or sleep problems
• Supplement with 1-2 g/day of omega’s from fish oil and 250-500 mg/day of omega 6’s in borage oil (younger children at lower dose, teens/adults at higher dose)
• Also give calcium to improve absorption (500 mg/day)

Summary
• Vitamins – little difference (but probably needed)
• Vit B6 – many studies show that high-dose B6 helps some children and adults
• Minerals – many children need calcium supplement esp. if GFCF
– iron levels similar to “typicals”, but many need iron
– Lithium supplement may help many children
• Amino Acids – measure levels of amino acids and possibly neurotransmitters, and give customized supplement if needed
• Hair: low toxics in hair, suggesting poor detoxification
• Fatty Acids – most children with autism need fish oil (omega 3) with some omega 6 (evening primrose oil or borage oil)

Conclusion of Statistical Analysis
Many measurements correlate with severity of autism, and with subscales of severity – Caution: need to replicate with larger study
Conclusion
Children with autism are “Children with Starving Brains and Starving Bodies”
• Many need essential vitamins and minerals• Some need some amino acids• Many need essential fatty acids
Balanced diets rich in vegetables, fruits, and protein are needed
Supplements also needed in most cases, and have proven benefit
