The first step in designing a mood food diet is to remember that every person is different, as is every day.

Look at what foods you like to eat and what comprises your normal diet.
What is the status of your psychological and emotional health?
Access what personality trait you would like to modify.
Manipulate what foods will help to correct this imbalance.

In order to adjust the foods you eat to control your moods, you need to understand a few basic principles.  Certain foods act like a physiological ¡°switch¡± due to the nutrients in the food. It is the combination of the protein, carbohydrate and fat (macronutrients) content, and the vitamins and minerals (micronutrients) that affect your mood.  

Your mood can be related to a deficit of nutrients; it may be as simple as an inadequate, poorly balanced diet, or it could be just one nutrient triggering a mood reaction. Some foods can enhance positive moods like water, fiber-rich foods, oil-rich fish, fruits and vegetables, while other foods can increase negative moods such as foods high in caffeine, alcohol or sugar.
