| Outline of Final Research Achievements |
We examined the relationship between mothers’ fish intakes and n-3 fatty acid metabolism during the lactation period and the growth and development of their infants. The compositions and concentrations of the n-3 fatty acid docosahexaenoic acid (DHA) in maternal milk were significantly positively correlated with the mothers’ fish intakes. The C/C type of the rs174547 SNP in the delta-5 fatty acid desaturase gene was found in 15% of mothers, the DHA composition (wt%) of maternal milk of mothers with the C/C type was significantly lower than that of mothers with the T/T type. When the growth of infants was analyzed according to the DHA concentration ingested from birth to 7 months, no association was found between DHA concentration and the weight gain of infants. We believe that further analysis is required to clarify the relationship between DHA ingestion and growth in infants.
