The Effect of TUBER Recommendations and the DASH Diet on Blood Parameters in Patients With Gestational Diabetes

The aim of this clinical trial was to examine the effects of the Turkish Nutrition Guide Recommendations Diet and the DASH Diet on blood sugar, blood pressure, and biochemical parameters in patients with gestational diabetes. The study hypotheses are as follows: Hypothesis 1: The DASH diet reduces fasting blood glucose levels more in patients with gestational diabetes compared to a diet adapted to a healthy diet specific to Türkiye. Hypothesis 1: The DASH diet reduces insulin levels more in patients with gestational diabetes compared to a diet adapted to a healthy diet specific to Turkey. Hypothesis 1: The DASH diet reduces HbA1c levels more in patients with gestational diabetes compared to a diet adapted to a healthy diet specific to Türkiye. Hypothesis 1: The Dash diet reduces 1st-hour postprandial glucose levels more significantly in women with gestational diabetes compared to a diet adapted to a healthy diet typical of Türkiye. Participants: After being diagnosed with gestational diabetes by a doctor using an OGTT test at 24-28 weeks, the researcher will complete a general information form during their first consultation with the dietitian. For four weeks, the dietitian will follow the diets created by the researcher based on their assigned diet group in a blinded manner. They will record their fasting and postprandial blood sugar levels in the morning, noon, evening, night, and during snacks, if they are taking them. They will keep a 24-hour food consumption record before meeting with the researcher weekly. Participants will have their biochemical parameters assessed at the beginning of the study and at the end of the fourth week.
