March 3, 2015 — In a Harvard study, the benefits of fish consumption on a developing fetus were clear. Researchers found that for every weekly serving of fish a mother ate while pregnant, her baby's score on visual recognition memory tests jumped four points on average, reports the New York Times.
The benefits did not end there. Babies whose mothers had two or more servings of fish per week also scored highest on memory tests.
The newspaper examined the issue of pregnant women eating fish as a result of the US Dietary Guidelines Advisory Committee's new nutrition recommendations, which withheld recommendation about tuna and argued that women who ate double the recommended weekly amount of tuna had benefits outweighing the risks.
