Specific therapeutic diets can complement the medical management of most common illnesses. Dietary modifications can be difficult to sustain, and patients may benefit from the support of a registered dietitian or other provider who can offer guidance. Eliciting a food recall is a helpful strategy to provide insight into a patient’s dietary preferences and restrictions and provides information about nutrient content in the current diet. Ongoing food tracking can improve dietary adherence and there are many online programs and applications that facilitate this activity.
Therapeutic diets can be divided into three groups: (1) diets that alter food consistency, (2) diets that restrict or modify dietary components, and (3) diets that supplement dietary components.
