Getting enough of two fish-oil components--DHA and EPA--seems to strengthen brain cell membranes and enhance cell-to-cell communication. The researchers advise focusing on fish in middle age to prevent mental decline, as well as heartbeat irregularities and joint inflammation, which the oils also help avert. Aim for one of these:
--Two to four meals a week of oily fish, such as wild Pacific salmon.

--Daily fish-oil capsules (500 mg EPA, 500 mg DHA).
