Estimated net endogenous acid production of diets in the Dietary Approaches to Stop Hypertension Trial scaled to 2100 kilocalories

	Control diet	Fruits and vegetable diet	Combination diet
Net endogenous acid production- Indirect (mEq/day)†	78.0	30.7	35.2
Potential renal acid load (mEq/day)‡	31.8	−23.7	−25.4
Protein (% kilocalories)	13.8	15.1	17.9
Servings of fruits and vegetables (number/day)	3.6	8.5	9.6

^†Estimated NEAP (mEq/d) = 54.5 [protein (g/day)/K (mEq/d)] − 10.2(25)

^‡Estimated PRAL (mEq/d) = 0.49 × protein (g/d) + 0.037 × P (mg/d) − 0.021 × K (mg/d) − 0.026 × Mg (mg/d) − 0.013 × Ca (mg/d)(22).

Phosphate (P) intake was not provided for diets and was estimated from 24 hour urinary phosphate assuming average intestinal absorption of 63%(2)
