If the question is about safety, yes, you can safely eat an Oreo cookie while pregnant. Oreos don't contain any unsafe ingredients. But, they are clearly not the choice you should make to fix a sweet craving during pregnancy. During pregnancy, you should focus on healthy, nutrient-dense food. Choose instead refined sugar-free cookies sweetened with dates, or maple syrup. Avoid processed food to bring a maximum of vitamins, fiber, and proteins to your body while avoiding unhealthy fats and added sugar.
