Safety of Seafood
Dietary intake of polyunsaturated fatty acids and fish among US children 12-60 months of age
Authors: Sarah A. Keim and Amy M. Branum / Journal: Maternal and Child Nutrition October 2013, September 2013Summary
In a study designed to estimate intake of PUFAs, identify sources of PUFA and estimate the proportion of US children aged 12-60 months eating fish by age, race and ethnicity it was found that 47% of children do not consume fish. The results from the study indicated DHA intake was low across all groups, and only 53.7% of children reported eating fish in the last 30 days. The study also found a greater percentage of non-Hispanic black children ate fish overall, and Mexican American children were more likely to have eaten shellfish than non-Hispanic white children. Total n-3 intake did not significantly change with age, but total n-6 intake increased significantly. Compared to other countries, US children consumed higher intake of total n-6 and demonstrated lower DHA and EPA intakes.
Autism Spectrum Disorder Phenotypes and Prenatal Exposure to Methylmercury
Authors: Edwin van Wijngaarden, et al. / Journal: Epidemiology, July 2013Summary
There has been speculation about a link between exposure to mercury during pregnancy and autism spectrum disorders, but limited data to support the theory. Researchers studied nearly 1800 mother/child pairs in the Republic of Seychelles, where people eat fish-rich diets and mercury levels are 10-20 higher than in the U.S. There was no association between exposure to mercury from eating a fish-rich diet during pregnancy and autism-like behaviors among 10-year-old children.
Fish Consumption and Prenatal Methylmercury Exposure: Cognitive and Behavioral Outcomes in the Main Cohort at 17 Years from the Seychelles Child Development Study
Authors: P. Davidson, et al. / Journal: NeuroToxicology, December 2011Summary
The people of the Seychelles Islands eat fish daily and their mercury levels are among the highest in the world, over ten times that of samples in the United States. Researchers studied the children in this population through age 17 and found no consistent pattern of harm from prenatal mercury exposure. In fact, there was evidence of improved performance as prenatal mercury exposure increased because mercury is a marker for fish consumption, which contains nutrients with long-lasting brain benefits.
