Understanding the Different Types of Starch
Starch is a complex carbohydrate found in many plants, including potatoes, corn, and rice. When part of a cooked meal, starch is a vital energy source. However, the isolated, concentrated powder used for cooking and, especially, for laundry is not meant for direct consumption. The key difference lies in the processing and potential additives. Cooking starches like cornstarch are typically non-toxic in their pure form but are designed to swell and thicken when heated, which presents an issue when consumed raw. Laundry starches, particularly older or industrial versions, may contain a cocktail of non-food-grade chemicals like borax, magnesium salts, and polishing agents, making them significantly more dangerous.
Immediate Health Effects of Drinking Cooking Starch
If a person drinks a significant amount of raw cooking starch (like cornstarch) mixed with water, the most immediate and likely consequence is a gastrointestinal issue. The powder is hygroscopic, meaning it absorbs water readily. Once it hits the acidic environment of the stomach and small intestine, it can swell and form a thick, pasty, and potentially obstructive mass.
Symptoms of this initial reaction may include:
- Severe stomach pain and cramping
- Nausea and vomiting
- Diarrhea, though severe blockages can cause constipation
- Intestinal blockage or obstruction, a serious condition requiring medical intervention
While pure cooking starch is generally considered non-poisonous, the physical obstruction it causes can be dangerous. The body struggles to pass the thickened substance, and if left untreated, a complete bowel obstruction is a medical emergency that could lead to bowel rupture.
The Real Dangers: Chronic Ingestion and Laundry Starch
Drinking laundry starch or consuming cooking starch over a long period due to a condition called pica is where the risks escalate dramatically. Chronic ingestion of laundry starch exposes the body to potentially toxic additives. The long-term effects are far more severe and systemic.
Symptoms of Chronic Starch Ingestion
- Kidney and Bladder: Decreased or no urine output, which can lead to kidney failure.
- Liver: Yellowing of the skin and eyes (jaundice) due to liver damage.
- Nervous System: Neurological symptoms including drowsiness, convulsions, twitching, and in severe cases, coma.
- Cardiovascular: Changes in heart rate, fever, and low blood pressure.
- Skin: Blisters, peeling, and a bluish tint to the skin, lips, or fingernails, indicating poor circulation.
- Nutrient Deficiency: Chronic ingestion can displace nutrient-dense foods, leading to malnutrition.
What to Do in Case of Starch Ingestion
Immediate action is critical, especially if laundry starch is involved. Do not wait for symptoms to worsen. The first step is to contact a poison control center immediately. In the US, the toll-free Poison Help hotline is 1-800-222-1222. They will provide instructions on the next steps, which may include drinking water or milk. Only induce vomiting if specifically instructed to by a medical professional.

Starch Ingestion Risks: Cooking Starch vs. Laundry Starch
| Feature | Cooking Starch (e.g., Cornstarch) | Laundry Starch (Liquid or Powder) |
|---|---|---|
| Primary Risk | Gastrointestinal blockage due to swelling and thickening. | Severe systemic toxicity from chemical additives like borax. |
| Toxicity Level | Generally non-toxic in its pure form, but can cause physical harm in large quantities. | Can be highly toxic, especially with chronic exposure. |
| Immediate Symptoms | Stomach pain, vomiting, potential obstruction. | Upset stomach, vomiting, diarrhea, irritation. |
| Long-Term Symptoms | Can lead to malnutrition and digestive issues if part of pica. | Kidney and liver damage, neurological problems, cardiovascular issues. |
| Required Action | Contact poison control; may require medical monitoring for obstruction. | Immediate medical evaluation and treatment for potential poisoning. |
Who is at Risk?
The risk of deliberately drinking starch is often associated with pica, a disorder characterized by a craving for and consumption of non-food items. Pica is most commonly found in children, pregnant women, and individuals with developmental disabilities or mineral deficiencies like iron deficiency anemia. Unintentional ingestion can happen to anyone if a substance is mistaken for a beverage or food item, highlighting the importance of proper storage and labeling.
Conclusion: The Final Verdict on Drinking Starch
In short, you should never drink starch, whether it's the cooking or laundry variety. While accidental ingestion of a small amount of cooking starch might only result in an upset stomach, consuming large quantities or laundry starch poses a serious and potentially life-threatening risk. The immediate danger is gastrointestinal blockage, while prolonged ingestion can lead to severe organ damage and systemic toxicity from chemical additives. It is imperative to treat any significant ingestion as a medical emergency and seek immediate assistance from a poison control center or healthcare provider. A healthy diet includes starch from natural sources like cooked whole grains and potatoes, not from raw, concentrated powder. Proper education and secure storage of household products are essential for preventing such dangerous accidents.
