    Abstract:
    BACKGROUND: There are claims that dietary supplementation of unsaturated fatty acids could help children with dyslexia to overcome their reading problems. However, these claims have not yet been empirically tested. METHODS: This study was designed to test whether dietary supplementation was superior to placebo in treating reading, spelling or other reading-related skills of children with dyslexia. The experimental group (eicosapentaenoic acid, EPA, n = 30) ate dietary supplements and the control group (placebo, n = 31) placebos during the 90-day treatment period. The supplements contained omega-3 fatty acid (ethyl-EPA, 500 mg/day) and carnosine (400 mg/day). The groups were matched for reading skills, grade, gender, attention problems, intelligence and amount of special education. The literacy-related skills of the two groups were assessed before and after the treatment period. RESULTS: No group differences were observed between EPA and placebo in measures of reading accuracy or speed, spelling, decoding fluency, arithmetical skills, reading-related language skills, attention or behavioural problems. CONCLUSION: The present findings do not support the hypothesis that omega-3 fatty acid (ethyl-EPA) or carnosine has a role in the treatment of reading and spelling problems in children with dyslexia.
