Cornstarch, also known as corn flour or maize starch, is a fine, powdery starch made from the endosperm of corn. It is commonly used as a thickening agent in sauces, soups, and puddings, and is also a popular ingredient in gluten-free baking.
But what is the nutritional value of cornstarch, and is it healthy for you? Let’s take a closer look.
One tablespoon of cornstarch contains approximately:
- 102 calories
- 26 grams of carbohydrates
- 0 grams of fat
- 0 grams of protein
- 0 grams of fiber
As you can see, cornstarch is primarily composed of carbohydrates. It has very little in the way of protein, fat, or fiber.
Cornstarch also contains trace amounts of some vitamins and minerals, including:
- Thiamin (vitamin B1)
- Niacin (vitamin B3)
- Folate (vitamin B9)
- Iron
However, it is important to note that the amount of these nutrients found in cornstarch is very small and is not likely to make a significant contribution to your daily intake.
Is Cornstarch Healthy for You?
So, is cornstarch healthy for you? The answer is not straightforward, as it depends on how you use it and how much you consume.
One potential concern with cornstarch is that it is a high-glycemic index food, meaning that it can cause a rapid increase in blood sugar levels. This can be especially problematic for people with diabetes or those at risk of developing diabetes, as it may lead to insulin resistance and an increased risk of heart disease.
However, the glycemic index of a food is not the only factor to consider when determining its impact on blood sugar. The glycemic load, which takes into account the portion size of the food and the amount of carbohydrates it contains, is a more accurate measure of a food’s impact on blood sugar. One tablespoon of cornstarch has a glycemic load of about 5, which is considered low.
Another potential concern with cornstarch is that it is derived from genetically modified (GM) corn, which has been genetically altered to resist pests and herbicides. Some people are concerned about the potential health effects of GM foods, although the scientific consensus is that GM foods are safe to eat.
It is also worth noting that cornstarch is often used as a thickening agent in processed foods, such as packaged sauces and soups. These foods tend to be high in sodium, sugar, and other additives, which may not be good for your health if consumed in large quantities.
In summary, cornstarch is not a particularly nutritious food, as it is primarily composed of carbohydrates and has very little in the way of protein, fat, or fiber. However, it is generally considered safe to eat in small quantities, especially when used as a thickening agent in homemade sauces and soups. It is important to be mindful of the glycemic index and glycemic load of cornstarch, as well as its potential sources (such as GM corn) and how it is used in processed foods. As with any food, it is important to consume cornstarch in moderation as part of a balanced diet.
