A common saying, but how can I eat happiness I hear you say? Fear not, tryptophan, an effective and common anti-depressant, increases our serotonin just like sunlight and is found naturally within many foods. Try snacks containing dark chocolate, strawberries, dates, sunflower/pumpkin seeds and bananas. Have porridge for breakfast as oats are full of tryptophan; make sure you add your milk to it as it is also a great source. Other sources are eggs and fish so make sure to incorporate them into meals too.
Hopefully these handy, easy and natural tips will help you carry on smiling until summer!
