Elimination of excess acid loads in metabolic acidosis requires stimulation of ammoniagenesis. Cortisol is critical to increase proximal tubular cells’ ammonia production. We aimed to specifically examine whether children’s low fruit and vegetable (FV) intake, which goes along with an increased dietary acid load, may raise cortisol secretion and whether glucocorticoids relevantly associate with ammonium secretion. Healthy 6–10...
