Using cornstarch with water multiple times a day to control blood sugar is not a safe or recommended medical treatment for the general public, including those with diabetes. It could cause dangerous blood sugar spikes and poses several other health risks.
The only medical context where uncooked cornstarch is deliberately used is for specific, rare metabolic conditions like glycogen storage disease (GSD), and this is done under strict medical supervision and with careful dosing.
How cornstarch affects blood sugar
Cornstarch is a highly refined carbohydrate with a high glycemic index, meaning it is quickly digested and causes a rapid and significant spike in blood glucose levels. This effect is particularly dangerous for individuals with diabetes, as it can be very difficult to manage.
Risks of using cornstarch for blood sugar control
High blood sugar spikes: Uncooked cornstarch is rapidly converted to glucose in the body, leading to an unwanted and potentially dangerous rise in blood sugar. This is the opposite of what is needed for stable blood sugar control in people with diabetes.
Poor nutrition: As a processed, refined carbohydrate, cornstarch offers virtually no nutritional value in the form of fiber, protein, vitamins, or minerals. Repeatedly consuming it throughout the day in place of nutritious foods can lead to nutrient deficiencies.
Weight gain and metabolic issues: A diet high in refined carbohydrates like cornstarch can contribute to weight gain, increased triglycerides, and poor blood sugar control. This can worsen metabolic issues and increase the risk of heart disease.
Gastrointestinal problems: Consuming significant amounts of raw cornstarch can cause digestive issues like bloating, gas, and stomach upset.
Masking a medical condition: Self-treating with cornstarch can mask an underlying medical issue, especially in individuals prone to hypoglycemia. This delays proper diagnosis and medical treatment.
When is cornstarch medically used?
Uncooked cornstarch is a specialized treatment for certain rare, inherited metabolic disorders, such as glycogen storage disease (GSD).
How it works in GSD: People with GSD cannot properly break down glycogen for energy. Doses of uncooked cornstarch are given to provide a slow, steady release of glucose into the bloodstream, helping to prevent episodes of hypoglycemia (low blood sugar).
Strict supervision is essential: This therapy is only administered under the strict supervision of a medical specialist, like an endocrinologist. Dosage and timing are carefully calculated and managed to avoid complications like dangerously high blood sugar.
Consult a healthcare professional
It is critical to speak with a doctor or registered dietitian before attempting to use cornstarch or any other unproven method to manage your blood sugar. A healthcare professional can help you develop a safe and effective plan to manage your condition based on your specific health needs.
