Pregnancy often comes with a variety of unusual cravings, but a strong desire to consume non-food items like raw cornstarch can be alarming. Cornstarch is a refined carbohydrate, also known as maize starch, typically used as a thickening agent in cooking. While it is not inherently toxic, its consumption in large, raw quantities during gestation is not recommended and signals a need for medical attention.
Immediate Health Concerns of Ingestion
Consuming cornstarch in significant amounts poses several direct health challenges, primarily related to its composition as a pure, highly-processed starch. It offers “empty calories,” meaning it contains a high energy density from carbohydrates but virtually none of the vitamins, minerals, or protein necessary to support a healthy pregnancy, leading to excessive weight gain without proper nutrition.
The physical nature of the starch also presents gastrointestinal issues for the expectant mother. Cornstarch is highly refined and difficult for the digestive system to process when ingested dry and in bulk. This can lead to severe constipation, which is already a common complaint during pregnancy, and may potentially cause an intestinal blockage in serious cases. Furthermore, the excessive consumption of starch may interfere with the absorption of other nutrients from food, potentially worsening any existing deficiencies.
Pica: The Underlying Craving
The intense, persistent craving to eat non-food substances like cornstarch is medically recognized as Pica, an eating disorder. When the craving is specifically for starches, such as cornstarch or laundry starch, it is sometimes referred to as amylophagia.
Pica is considered a serious medical concern during pregnancy because it is strongly associated with nutritional deficiencies. The most frequently hypothesized link is to iron-deficiency anemia, but it can also be connected to low levels of zinc. Studies show that pregnant individuals who exhibit Pica often have significantly lower iron levels compared to those without the cravings. The body may be attempting to correct a nutritional deficit by triggering a craving for a non-nutritive substance, though the exact biological mechanism remains unclear. Treating this type of craving as a behavioral issue misses the underlying physiological cause, as Pica is a sign that the body’s nutritional status may be compromised due to the increased demands of pregnancy.
Treatment and Support for Pica
If you experience a persistent desire to consume cornstarch or any other non-food item, immediately inform your obstetrician or healthcare provider. The medical team will typically order blood tests to check for underlying nutritional deficiencies, specifically looking at iron status and other mineral levels. Treatment for Pica focuses primarily on correcting the identified deficiency. If iron-deficiency anemia is confirmed, the provider will prescribe appropriate iron supplementation. For many individuals, addressing the anemia with supplements and improving overall nutrition is enough to resolve the cravings completely. Distraction and behavioral techniques, such as chewing sugarless gum or finding safer, non-caloric alternatives like ice chips, can also be helpful in managing the impulse while the underlying issue is being treated.
