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.
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.
