Prozac from the Sea
Fatty fish is the best dietary source of DHA and EPA. Ounce for ounce, you get the biggest omega-3 bang for your buck with salmon, herring, lake trout, anchovies and sardines. Other seafood is better than a pork chop but ahs considerably less of these mood- and mind-boosting fats. All the research on omega-3 and mood has used either seafood or supplements; both work equally well at keeping people happy and smart.
Your mood and mind go up and down with how much fish you eat. Eat fatty fish twice a week and you reduce the risk for developing memory loss by 28%, according to a study from Tufts. On the other hand, eat it less than once a week and depress risk goes up 34%.
