The vast majority of us reach for comfort foods when we're feeling low. And while you've heard me preach time and again that that's not a good idea, new research shows that there is something you should snack on when you need a pick-me-up — omega-3 fatty acids! Researchers from the University of Pittsburgh recently discovered that omega-3s not only protect your heart and cut your risk of serious diseases, they can also give you a mood boost! Talk about a win-win situation!

So where can you find these feel-good nutrients? Fattier fish like mackerel, lake trout, herring, sardines, albacore tuna, and salmon are all high in omega-3s. Not a seafood fan? You can also find omega-3s in tofu and soybeans, as well as in canola, walnut, and flaxseed oils. Finally, fish oil supplements also contain omega-3s, but be careful not to take more than 3 grams a day — overdoing it on omega-3s can have harmful side effects, such as increased bleeding and a higher risk of stroke.

The next time you're having a bad day, opt for omega-3s instead of ice cream and do your body — and your mood — good!

Don't be afraid to ask questions when dining out! It's your responsibility to make healthy choices, not your waiter's.
