From fast food to a bowl full of leafy greens, snacking on something we enjoy is a guaranteed pick-me-up. But not all food types are good for us in the long term. Here's a list of the mood-boosting foods that will keep you happy and healthy.

For obvious reasons, chocolate makes us very happy. But it doesn't just provide an instant fix to a low mood, it is also rich in magnesium, which helps calm your muscles and reduce anxiety.

Oysters might not be quite as tasty as chocolate, but these slippery shellfish are packed full of essential vitamins for a happier life, including protein, iron, omega 3 fatty acids, calcium and Vitamin C. The high quantity of Omega-3 fatty acids means oysters help to boost brain activity and reduce depression.

Popeye's favorite leafy greens have some key components for improving your mood and helping prevent you from becoming depressed. Both folic acid and magnesium are key to mood boosting and can leave you feeling motivated for the rest of the day.

Packed full of potassium, bananas don't just provide an energy boost and make you fuller for longer. The curved yellow fruits also help to battle depression due to high levels of tryptophan, which converts into serotonin to produce our happy moods.

If you want your mood to be as sunny as your eggs, then eating them regularly will certainly help. Yolks aren't just tastiest part of the egg, but they're also full of L-tryptophan to help increase happy hormones. Eggscellent!

A lot of us rely on a regular caffeine fix to boost our mood throughout the day, and it really does just that. But as well as giving us a temporary buzz, coffee is also known to lower risks of depression and increase dopamine and serotonin.
