4. Salmon
This cold water, fatty fish is loaded with nutrients and has been found to provide some profound effects on both physical and mental health. Salmon is high in omega-3 fatty acids, which have been found to increased good cholesterol levels (HDL) by as much as four percent. Omega-3 fatty acids can also ward off dementia and Alzheimer’s disease. This fish also serves up healthy doses of vitamin B12, potassium and selenium. Throw a salmon filet on a cedar plan and grill it up, or pan sear it and serve it on top of a salad or mix it in with pasta.
