Can Eating Cornstarch Kill You?

Cornstarch is a versatile and commonly used ingredient in cooking and baking. It is derived from the endosperm of corn kernels and is often used as a thickening agent in sauces, soups, and gravies. However, some people consume cornstarch in large quantities as a craving or due to a medical condition called pica.

This raises the question, can eating cornstarch kill you?

Yes, consuming large amounts of cornstarch can potentially be harmful and even fatal. Cornstarch is made from corn and is primarily composed of carbohydrates. While it is generally considered safe for consumption in small quantities, ingesting excessive amounts can lead to various health risks.

Risks of Excessive Cornstarch Consumption

Eating excessive amounts of cornstarch can cause a condition called “pica,” which is characterized by a compulsive craving to eat non-food items, such as cornstarch, clay, dirt, or ice. Pica can lead to serious health consequences because these non-food items are not meant to be ingested and can disrupt normal digestion and nutrient absorption.

Pica is more common in children and pregnant women but can affect anyone. It is usually a result of a nutrient deficiency or a psychological disorder. In some cases, it can also be a side effect of medication.

Additionally, consuming large quantities of cornstarch can lead to a rapid spike in blood sugar levels due to its carbohydrate content. This can be especially dangerous for individuals with diabetes or those who are at risk of developing diabetes.

In extreme cases, consuming very large quantities of cornstarch could potentially lead to choking or gastrointestinal blockages, which can be life-threatening.

Other risks include:

  • Choking Hazard: Cornstarch can form a thick paste in the mouth and throat, which can lead to choking, especially in children.
  • Digestive Problems: Consuming excessive cornstarch can lead to digestive problems such as bloating, gas, and constipation. This is because cornstarch is difficult to digest and can slow down the digestive process.
  • Blood Sugar Spikes: Cornstarch is a high-carbohydrate food that can cause a rapid spike in blood sugar levels. This can be particularly dangerous for people with diabetes.
  • Malnutrition: Consuming large quantities of cornstarch can displace other nutrient-rich foods in the diet, leading to malnutrition and vitamin deficiencies.
  • Asphyxiation: In rare cases, excessive consumption of cornstarch can lead to asphyxiation or suffocation, particularly in people with a history of respiratory problems.

If you or someone you know is intentionally consuming non-food items like cornstarch or experiencing unusual cravings, it’s important to seek medical attention to address the underlying causes and potential health risks.

Effects of Cornstarch on the Body

Cornstarch is a source of carbohydrates and contains very little nutritional value. Excessive consumption of cornstarch can lead to several negative effects on the body. Some of the effects include:

  • Weight Gain: Cornstarch is a high-calorie food that can contribute to weight gain and obesity when consumed in excess.
  • High Blood Sugar Levels: As mentioned earlier, cornstarch is a high-carbohydrate food that can cause a rapid spike in blood sugar levels. This can lead to insulin resistance and increase the risk of developing type 2 diabetes.
  • Poor Dental Health: Cornstarch is a starchy food that can stick to teeth and promote the growth of harmful bacteria in the mouth. This can lead to tooth decay and gum disease.

Prevention of Excessive Cornstarch Consumption

The best way to prevent excessive cornstarch consumption is to consume it in moderation. If you have pica or a craving for cornstarch, it is important to seek medical advice to determine the underlying cause. Treating the underlying cause can help alleviate the craving for cornstarch.

If you are using cornstarch as a thickening agent in cooking, it is important to follow the recommended guidelines and not exceed the recommended amount. When using cornstarch as a thickener, it is also important to mix it with a cold liquid before adding it to a hot liquid to prevent clumping.

In addition, if you or someone you know has a history of excessive cornstarch consumption, it is important to seek medical attention. A doctor can evaluate your overall health and provide guidance on managing the condition and preventing future episodes.

Final Thoughts

While cornstarch is generally safe when consumed in moderation, excessive consumption can pose several risks and negative effects on the body. Pica, a medical condition characterized by a craving for non-food items such as cornstarch, can also lead to excessive consumption of cornstarch.

It is important to seek medical advice if you have a craving for cornstarch or suspect that you may have pica. Preventing excessive cornstarch consumption involves consuming it in moderation, following recommended guidelines when using it as a thickening agent, and seeking medical attention if needed.

By being aware of the risks and effects of excessive cornstarch consumption, we can make informed decisions about our diet and maintain good health.
