Response to Response to Sharma Parpia et al. (2018): The accuracy of Canadian Nutrient File data for reporting phosphorus, potassium, sodium and protein in select meat, poultry and fish products

“…After making the adjustments to CNF comparison values suggested by Verreault et al (2021), we continue to observe significant discrepancies in mean chemically analyzed and CNF values. We now report that 20% of the analyzed food categories have significant discrepancy for sodium (decreased from 30%), 30% for potassium (decreased from 40%), 20% for phosphorus (no change) and 30% for protein (decreased from 40%).…”

“…We read with great interest the response from Verreault et al (2021). Our intention was to highlight for health care professionals in particular that there may be significant differences between the foods their patients are consuming and the values stated in the Canadian Nutrient File (CNF) (Sharma Parpia et al, 2018).…”

“…As stated previously, our data are limited by geographic location. Verreault et al (2021) state that "management of patients with chronic kidney disease [CKD] should be based on the nutrient composition of the specific foods in their diets"; however, it is not practical to chemically analyze the specific foods of individual patients, nor do many such meats provide Nutrition Facts tables (NFt). The NFt, when available, may not include values for key nutrients of concern for CKD patients such as potassium and phosphorus .…”
