Excerpt from www.askdrsears.com
Fish is good brain food. Not only is fish good for the heart, it's
good for the head. Fish oils are healthy because they contain the
two essential omega 3 fatty acids: EPA and DHA, which are
particularly valuable as nutrients for the cells of the brain and
nervous system, the eyes, and the adrenal and sex glands. Come to
think of it, those are the organs that helps us think, see, and
enjoy sex. Fish food = good brain and heart food.
