Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Blood samples were taken after an overnight fasting. Dietary information was obtained by mean intakes of a 3-day food records (2 weekdays and 1 weekend day) and analyzed via nutrition analysis software. According to the data obtained from software analysis, animal protein (g/day) to potassium (g/day) ratio (AP/K), potential renal acid load (PRAL; mEq/day) score and net endogenous acid production (NEAP; mEq/day) were calculated from established algorithms to estimate dietary acid load. All nutrients were age and energy- adjusted before being introduced into the equation and tertiles of the scores were used for statistical analysis. ANOVA, ANCOVA and Logistic regression test were used. The study plan was approved by the Hospital\'s Ethics Committee.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Women with gestational diabetes
We randomly selected the 40 pregnant women diagnosed GDM by two-step procedure based on Carpenter-Coustan criteria at this hospital. The diagnosis of GDM was confirmed if at least 2 of 4 glucose levels exceed based on Carpenter-Coustan criteria: fasting ≥ 95 mg/dL (5.3 mmol/L), 1 hour ≥ 180 mg/dL ( 10.0 mmol/L), 2 hour ≥ 155 mg/dL (8.6 mmol/L), and 3 hour ≥ 140 mg/dL (7.8 mmol/L).
No interventions assigned to this group
Healthy women
We also randomly selected 40 healthy pregnant with normal serum glucose levels ≤129 mg/dL (7.2 mmol/L) after GCT.
No interventions assigned to this group
