Gestational diabetes is characterized by elevated blood glucose levels found during pregnancy in individuals who did not previously have diabetes. Overall, dietary control for gestational diabetes is similar to that for typical diabetes patients. It involves avoiding high-calorie, high-sugar, and fried foods. It is advisable to consume more fruits and vegetables, as well as foods with a lower glycemic index. Increasing the intake of whole grains and mixed grains is recommended, while nuts such as peanuts and sunflower seeds should be limited. Foods should be steamed rather than boiled, and fried foods must be strictly avoided.
