Which nutrient is most commonly associated with the prevention of heartburn during pregnancy?

Fiber is recognized as a crucial nutrient in preventing heartburn during pregnancy. One of the reasons fiber is beneficial in this regard is that it aids in digestion and helps regulate bowel movements. When a pregnant individual consumes sufficient fiber, it can help minimize issues such as constipation, which can contribute to increased pressure in the abdominal area and exacerbate heartburn symptoms. Furthermore, fiber can promote a feeling of fullness, potentially reducing the likelihood of overeating, which is another factor that may trigger heartburn.

Additionally, dietary fiber can help in managing weight gain during pregnancy, which is significant because excessive weight gain can increase the risk of heartburn due to heightened pressure on the stomach. Incorporating fiber-rich foods like fruits, vegetables, whole grains, and legumes can thus play a role in alleviating discomfort during pregnancy related to heartburn.
