Nutritional Goal

Adapted from: https://clinicalnutrition.science/en/

Optimal nutrition is meant to prevent deterioration of mental and physical functions as well as health or treatment complications and to shorten convalescence. The «Nutritional Risk Screening» (NRS) is suitable for detecting malnutrition. The following calculator can be used to calculate individual protein and caloric goals. The formulas used were tested in the EFFORT study.[1]
