What you need: Serotonin

Research has found that eating carbohydrates stimulates the brain`s production of serotonin - the happy hormone. This may be why many of us crave stodgy `comfort` foods such as pasta and bread when we are feeling blue.

Healthy swap: Sweet potatoes, lentils, beans

To get a healthy fix of carbs (minus the blood sugar crashes and energy slumps) opt for nutritious and low GI carbohydrates which will release a steady supply of energy and keep you feeling full for longer. Good sources of complex carbohydrates include beans, lentils, oats and sweet potatoes.

As well as switching your carbohydrate sources, you can also reduce cravings by boosting your serotonin levels through exercise and mood-boosting activities. Try using uplifting essential oils such as neroli and lemon which also stimulate the production of serotonin in the brain.
