A healthy gestational diabetes diet focuses on keeping blood sugar stable by eating balanced meals with complex carbohydrates (whole grains, oats, brown rice), lean protein (eggs, beans, chicken), and healthy fats (nuts, seeds, olive oil). It’s best to have 3 small meals and 2–3 snacks daily, spreading carbohydrates evenly (about 30–45g per meal) and always pairing them with protein or fat to prevent spikes. Choose low glycemic index foods like vegetables, legumes, and high-fiber options, and avoid or limit sugary foods, fruit juices, white bread, fried snacks, and processed items. Consistent meal timing, portion control, and balanced nutrition help manage blood sugar while supporting a healthy pregnancy.
