The latest studies across the world show that diet can improve mental health. Therefore, diet is considered an important part of the treatment. A healthy and balanced diet can prove to have a drastic change in mood. Items in a diet can have negative or positive effects on a person's mood. The same is the case with the quantity of consumption.
For eg., If a kid is hyperactive, sugar should be avoided completely to evade the symptoms of hyperactivity. Similarly, certain fruits & vegetables, if consumed by a person, can help cure the symptoms of depression or anxiety.
