It is important to increase adequate intake of healthy fats the brain and body need.  Omega 3 is a healthy fatty acid that is essential, meaning it must come from your diet, by eating fatty fish such as salmon, several times a week or be gained through supplements.  The active compounds in omega 3 are DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) and they are only found in fish.
