This research examined the relationship between mothers' consumption of various types of seafood during pregnancy and attention capacity in children at eight years of age. The study found that mothers eating a seafood-rich diet during early pregnancy had children with better attention outcomes. The consumption of seafood during the first trimester of pregnancy had a greater effect on children’s attention capacity than the consumption of seafood later in pregnancy. Children whose mothers ate a diet rich in various types of seafood scored very well on the attention tests, as did children of women with a diet rich only in fatty fish. However, scores were lower in children whose mothers relied on canned tuna or shellfish for their seafood intake.
