Why Do Black People Eat Cornstarch? Understanding Pica, Cultural History, and Modern Practices
The consumption of cornstarch, often associated with Black communities, is primarily linked to pica, a condition characterized by cravings for non-nutritive substances; however, it’s also connected to cultural history and perceived health benefits, particularly during pregnancy. While pica can affect individuals of any race, cornstarch consumption holds unique historical and cultural significance within the Black community.
Historical and Cultural Context
The association of cornstarch with Black people, particularly in the Southern United States, stems from several interwoven factors: the legacy of slavery, socioeconomic conditions, and traditional folk remedies. Understanding this history is crucial to de-stigmatizing the practice.
- Slavery and its Aftermath: During slavery, enslaved people often lacked access to adequate nutrition. The consumption of non-food items like clay and dirt, a practice called geophagy, was common, potentially as a way to supplement mineral deficiencies.
- Poverty and Food Deserts: Even after emancipation, persistent poverty and limited access to nutritious food in many Black communities contributed to food insecurity and, consequently, to the prevalence of pica. Cornstarch, being readily available and relatively inexpensive, became a common craving.
- Cultural Significance: Over time, the consumption of cornstarch became embedded in some cultural practices, particularly among pregnant women. It was sometimes seen as a way to alleviate morning sickness, heartburn, or other pregnancy-related discomforts.
Pica and Cornstarch
Pica is a complex eating disorder characterized by persistent cravings and consumption of non-nutritive substances for at least one month. While the exact cause of pica is unknown, several factors are believed to contribute:
- Nutritional Deficiencies: Iron deficiency anemia, zinc deficiency, and other nutritional imbalances are often implicated in pica. The body may be attempting to compensate for these deficiencies through the consumption of unusual substances.
- Psychological Factors: Stress, anxiety, obsessive-compulsive disorder (OCD), and other mental health conditions can also contribute to pica.
- Cultural Practices: As noted earlier, cultural traditions and beliefs can influence the types of non-food items craved and consumed.
While cornstarch may provide temporary satisfaction, it offers no nutritional value. In fact, excessive consumption can lead to:
- Weight gain due to its carbohydrate content
- Constipation
- Dental problems
- Interference with the absorption of essential nutrients
The Perceived Benefits
Despite the lack of nutritional value, some individuals believe that cornstarch offers certain benefits, particularly during pregnancy:
- Relief from Heartburn: Cornstarch is sometimes believed to coat the esophagus and stomach, providing temporary relief from heartburn.
- Alleviation of Morning Sickness: Some pregnant women find that eating cornstarch helps to settle their stomachs and reduce nausea.
- Iron Absorption: The historical assumption was that cornstarch helped with iron absorption; however, modern science disproves this theory and in fact, may hinder nutrient absorption.
The Risks
While some believe cornstarch can ease pregnancy symptoms, the risks often outweigh the unproven benefits:
| Risk | Description |
|---|---|
| Nutritional Deficiencies | Cornstarch provides empty calories and can displace the consumption of nutrient-rich foods. |
| Weight Gain | Excessive consumption of cornstarch can lead to weight gain, which can increase the risk of pregnancy complications. |
| Constipation | Cornstarch can bind in the digestive system leading to blockage and constipation. |
| Dental Problems | The starch can contribute to tooth decay. |
| Gestational Diabetes | Eating too much cornstarch can quickly spike blood sugar, raising risk for gestational diabetes. |
Modern Perspectives and Medical Advice
Today, healthcare professionals discourage the consumption of cornstarch, especially during pregnancy. Instead, they recommend:
- Addressing Underlying Nutritional Deficiencies: If you have pica, consult with your doctor to determine if you have any nutritional deficiencies. Iron supplements or other dietary changes may be recommended.
- Managing Mental Health: If stress, anxiety, or other mental health conditions are contributing to your cravings, seek professional help.
- Healthy Diet: Eating a healthy, balanced diet that is rich in fruits, vegetables, whole grains, and lean protein is important to prevent nutritional deficiencies and cravings.
- Safe Alternatives: Discuss safe and effective ways to manage morning sickness, heartburn, or other pregnancy-related discomforts with your doctor.

No type of cornstarch is considered safe to eat in excessive amounts. All cornstarch lacks essential nutrients and can pose health risks.
Is cornstarch consumption more common in certain age groups?
While pica can affect people of all ages, cornstarch consumption seems more prevalent among pregnant women and young children experiencing nutritional deficiencies or psychological stress.
Does eating cornstarch lead to weight gain?
Yes, eating cornstarch can lead to weight gain because it is high in carbohydrates and provides empty calories without any essential nutrients.
How is pica diagnosed by a doctor?
A doctor diagnoses pica based on a patient’s history of consuming non-nutritive substances for at least one month. They will also conduct physical exams and blood tests to check for nutritional deficiencies.
What other non-food items are commonly craved besides cornstarch?
Besides cornstarch, other non-food items frequently craved in cases of pica include clay, dirt, ice, paper, chalk, and laundry starch.
How can parents prevent their children from developing pica?
Parents can prevent pica by ensuring their children have a balanced diet rich in essential nutrients, addressing any potential psychological stressors, and seeking medical advice if they suspect their child is consuming non-food items.
