This study aimed to determine the serum C-reactive protein (CRP) level at which the risk of low food intake increases in acutely ill older hospitalized patients. 377 patients were analyzed, with nutritional intake determined using the food intake item of Nutritional Risk Screening and the plate diagram method. Patients with food intake <50% of requirements had significantly higher median CRP levels (P < 0.001). A serum-CRP of 3.0 mg/dl appears to be a reasonable threshold for acute inflammation leading to reduced food intake in acutely ill older patients, relevant to the GLIM malnutrition diagnosis.
