Moderate evidence indicates that increased maternal dietary intake of long chain n-3 polyunsaturated fatty acids (PUFA), in particular docosahexaenoic acid (DHA) from at least two servings of seafood per week, during pregnancy and lactation is associated with increased DHA levels in breast milk and improved infant health outcomes, such as visual acuity and cognitive development.

Alpha-linolenic acid (ALA) intake of 0.6-1.2 percent of total calories will meet current recommendations and may lower cardiovascular disease (CVD) risk, but new evidence is insufficient to warrant greater intake beyond this level. Limited, but supportive evidence suggests that higher intake of n-3 from plant sources may reduce mortality among persons with existing CVD.
Limited
Overall strength of the available supporting evidence: Strong; Moderate; Limited; Expert Opinion Only; Grade not assignable.
Moderate evidence shows that consumption of two servings of seafood per week (4oz per serving), which provide an average of 250mg per day of long-chain n-3 fatty acids, is associated with reduced cardiac mortality from coronary heart disease (CHD) or sudden death in persons with cardiovascular disease (CVD).
