When you suffer from depression, one of the most detrimental consequences of the illness is a lack of resilience, a factor that prevents the capacity to conquer the disease. Eating the right foods is important, and while sufferers of depression often find it like they don't want to eat at all, they must make the effort. It can help to have some fresh fruit and veg, as well as pasta or potato carbohydrates, instead of eating "comfort food," which is seldom very reassuring.
For mental wellbeing, drinking plenty of fluid is also necessary. Ideally, five or more glasses of water a day would keep your body and mind from being dehydrated and depriving you of the power that is so necessary. It is important to have the stamina and sharpness to send the effects of depression packing, and your diet will play a large part in this.
