A diet heavy in processed and fried foods, featured in United States southern cuisine, was independently associated with higher death rates among persons with chronic kidney disease (CKD) in a recent study.

The observational study, led by Orlando M. Gutiérrez, MD, MMSc, and published in the National Kidney Foundation’s (NKF’s) American Journal of Kidney Diseases (2014;64[2]:204-213), involved 3,972 persons who had CKD (defined as estimated glomerular filtration rate <60 mL/min/1.73 m2 or as albumin-creatinine ratio ≥30 mg/g at baseline) but had not begun dialysis. 

Over about 6 years of follow-up, 816 deaths and 141 end-stage renal disease events occurred. As noted in an NKF press release, persons who ate a diet of processed and fried foods, organ meats, and sweetened beverages, items popular in cuisine featured in the South, had a 50% heightened risk of death.
