Practice Consideration
Choices of Comparative Standard Reference Values
In cases where the patient is generally well, practitioners can make use of Comparative Standards and apply those against the national nutrition guidelines for healthy individuals. If the patient presents with a specific medical complaint requiring medical nutrition therapy, the dietitian will use dietary guidelines specific to the condition.
For an individual who has hypertension and is overweight, the most appropriate Comparative Standard would be a cardioprotective meal pattern, such as the DASH diet or equivalent. This allows the dietitian to make precise modifications to the patient's dietary intake.
The daily nutrient goals used in DASH studies for the 2 000 kcal plan(1) are as follows:
The daily physical activity goals used in DASH studies for the 2 000 kcal plan are:
Note — if the patient is returning for a follow-up consultation, the dietitian may use the previous Nutrition Prescription as the Comparative Standard. This would include energy requirements, ideal body weight and BMI calculated in the previous consultation.
