Abstract
Memory is a quintessential human ability which the nervous system can encode, store, and retrieve a
variety of information. Polyphenols are powerful antioxidant and regular intake of polyphenol-rich
observed improvements in learning, working, spatial, acquisition and retention of memory. The current
study was conducted to investigate the effectiveness of administration diets rich in some natural
antioxidants on the abilities of memory and nutritional status for primary school children with learning
disabilities. Twenty-seven children in age from (7 – 13) years in the primary school were diagnosed by the
psychologist and their teachers were enrolled in the study. Intelligence tests (Stanford Penny), learning
disabilities measure (Memory), Personal data, Anthropometric measurements and nutrition assessment
were used before and after diets intervention. The application of food intervention was carried out by
providing one category of meals daily, meal 1 contains (vanilla biscuit with yellow cornmeal + fruit cake
with cocoa jelly), meal 2 contains (chocolate cupcake with yellow cornmeal +fruit cake with red beet roots
jelly) and meal 3 contains (chocolate peanut butter biscuits+ vegetables salad) for 3 months frequency.
These meals contain polyphenols (quercetin, caffeic acid, P-coumaric acid and ferulic acid).
It was observed that prepared diets rich in some antioxidants had highly significant increase (P≤ 0.01) in
the mean value of memory (19.25±3.64) as compared to before test (11.66 ± 1.38), also improved some
nutritional and behavioral problems. It could be concluded that dietary intervention rich in polyphenols
could improve and enhance memory status in children with learning disabilities.
Keywords
