What are the difference between normal and therapeutic diets?

A healthy normal diet includes proteins, carbohydrates, fats, vitamins and minerals in small quantities. All these ingredients are important for the maintenance of health. The normal diet may be plant or animal based. Therapeutic diet, on the other hand, is implemented in emergency situation when a person has special nutrition requirements. The amount of protein, carbohydrates, fat, minerals and vitamins may vary depending upon the need.
