6. Get Fishy

Seafood is another great source of happiness. Yes, it’s absolutely delicious and you should feel happy just eating it but that’s not all. Research has actually found that omega-3 fatty acids that are present in oily fish actually help the brain to produce more serotonin and help it transmit it across the neurons more evenly. If you don’t particularly like fish, you could also get your dose of omega-3 fatty acids through natural supplements like cod liver oil capsules.
