The U.S. Dietary Guidelines Advisory Committee announced in a June 10, 2010 preliminary report on the 2010 Dietary Guidelines for Americans that we eat too little seafood and should be encouraged to eat more for heart health in adults and better brain development in babies. The 2010 Dietary Guidelines for Americans, scheduled to be released before the end of the year, are expected to recommend consuming a minimum of 2 servings of seafood per week. A serving is defined as 4 oz. (raw weight) or about the size of a deck of playing cards. The guidelines emphasize choosing those species with the least risk of mercury contamination and those fatty fish high in omega-3 fatty acids. The committee also recommended increasing seafood consumption to at least two servings per week for pregnant and lactating women.
