Like the old saying goes, you are what you eat. If you want to be happier, then you better start eating some good-for-you food! Junk food will weigh you down and depress your moods, whereas healthier foods will improve your body and brain health and lead to you feeling happier and more energized. Omega-3 fatty acids are especially good for your brain health and are necessary for survival, yet your body doesn’t produce them. You need to get them in the foods you eat, such as in fish like halibut, herring, salmon, sardines, snapper, swordfish, and tuna. Other good sources of omega-3 fatty acids are flaxseed and walnuts, wheat germ, pumpkin, and spinach. If you want a healthy heart and you want food for your brain, eat your omega-3s.
