A clinical trial called SMILES (Supporting Modification of Lifestyle in Lower Emotional States) for the treatment of depression was conducted and recently summarized in Australia and New Zealand. The result showed the strong therapeutic effect on depression by certain groups of food.
This study should be reviewed by all the psychiatrists and patients who are suffering from low mood.
Food was subdivided into 12 categories in this study:
- whole grains (5–8 servings per day);
- vegetables (6 per day);
- fruit (3 per day),
- legumes (3–4 per week);
- low-fat and unsweetened dairy foods (2–3 per day);
- raw and unsalted nuts (1 per day);
- fish (at least 2 per week);
- lean red meats (3–4 per week),
- chicken (2–3 per week);
- eggs (up to 6 per week);
- olive oil (3 tablespoons per day)
Define extra foods:
‘extras’ foods, such as sweets, refined cereals, fried food, fast-food, processed meats and sugary drinks (no more than 3 per week), red or white wine consumption beyond 2 standard drinks per day and all other alcohol (e.g. spirits, beer) were included within the ‘extras’ food group.
After 12 weeks of diet following categories 1 to 11, and exclusion of ‘extra’ foods, patients’ therapeutic outcome is significantly better than those who didn’t follow the diet, even though both groups have the counseling and group therapies meanwhile.
