Diet prescription.^a

Diet component	Target level	Focus
Dietary Acids	Reduce NEAP by 50% (minimum 40 mEq/d)	Increased fruits and vegetables were prescribed using a new fruit and vegetable point system. 1 point = 1 mEq reduction in NEAP.
Protein	0.8–1.0 g/kg body weight/d	A standard protein point system was prescribed to limit total protein intake, primarily animal protein.
Sodium	1–1.5 mmol/kg body weight	Daily limits were apportioned to limits for each meal and snack based on the individual’s usual dietary pattern. Sodium reduction guidelines from the American Heart Association were also provided [26].
Fluid	Reduce urine osmolality to 285 mosm/kg H2O	Subjects were given exact volumes of fluid to drink throughout the day to reduce urine osmolality to target level.
