If you’ve ever enjoyed soup, sauces, stir fry, pies, or other desserts, you’ve likely consumed cornstarch. Originally invented in the mid-19th century and initially used as a laundry aid, cornstarch was later recognized for its ability to thicken foods (via Martha Stewart). In fact, cornstarch can be twice as effective as flour in thickening.
Derived from the endosperm of the corn kernel, cornstarch is the most widely used thickening agent compared to other grain-based starches like rice, wheat, and potatoes. To activate its thickening properties, cornstarch must be heated to a simmering temperature. From there, it can be utilized in a variety of dishes. Best of all, it can last indefinitely in your kitchen if stored in a cool, dry location. Given that cornstarch is a crucial component in numerous meals and baked goods, could it be harmful to consume?
Potential Alternatives to Cornstarch
According to Healthline, cornstarch is high in carbohydrates and calories but low in beneficial nutrients. It can take 1 cup of cornstarch to start seeing some nutritional value, yet this is a much larger portion than you would typically consume. Usually, 1 or 2 tablespoons are used to thicken a soup. If you are seeking a healthier alternative to cornstarch when cooking or baking, Medical News Today suggests several options.
For example, if you can consume gluten, wheat flour is healthier than cornstarch due to its higher protein content and lower carbohydrate levels. However, wheat flour is not as starchy as cornstarch, so you may need to use more of it in your recipe. Rice flour is another proven substitute for cornstarch and, like wheat flour, contains more nutrients. Potato starch is another alternative. While it doesn’t have as many nutrients as rice and wheat flour, it is still significantly lower in calories than cornstarch. It is also a good option for those who require a gluten-free diet (via Medical News Today).
It’s important to be aware that if you crave eating raw cornstarch, it could indicate a disorder known as pica (via Livestrong). More research is needed, but health experts believe that pica may signal anemia or a deficiency in iron or zinc.
