When you hear someone laugh behind you, you probably picture them on the phone or with a friend – smiling and experiencing a warm, fuzzy feeling inside. Chances are just the sound of the laughter could make you smile or even laugh along. But imagine that the person laughing is just walking around alone in the street, or sitting behind you at a funeral. Suddenly, it doesn’t seem so inviting.
Your thoughts, moods and behaviours are the product of your brain – an exquisite spider’s web of neuronal connections and witch’s brew of neurochemicals. It is this brew that is prone to change, and when “unbalanced” can cause dramatically altered behaviour. And your diet may have more to do with how you think than you would first suspect.
