About Cornstarch

Cornstarch, derived from the endosperm of corn kernels, is a fine, white carbohydrate-based powder widely used as a thickening agent in cooking and baking. Originally developed in the United States in the mid-19th century, it is commonly incorporated into a variety of cuisines, particularly in sauces, soups, gravies, and desserts for its ability to create smooth textures. Nutritionally, cornstarch is almost purely composed of carbohydrates, providing energy but lacking essential vitamins, minerals, protein, and fiber. Its simplicity makes it a kitchen staple, but it is not a significant source of nutrients.

Health Benefits

• Provides quick energy due to its high carbohydrate content (87.5 grams per 100 grams).
• Can be used in low-protein recipes for those requiring protein limitations (protein-free).
• Gluten-free, suitable for individuals with celiac disease or gluten intolerance.

Dietary Considerations

Allergens: None known

Suitable for: Gluten-free diets, low-protein diets, vegan diets

Not suitable for: Low-carb diets, diets requiring high nutritional density

Selection and Storage

Store cornstarch in a cool, dry place in an airtight container to prevent moisture and clumping; it has a long shelf life if kept sealed.

Common Questions About Cornstarch Nutrition

Is cornstarch high in calories?

Yes, cornstarch is relatively high in calories, providing 375 calories per 100 grams. However, it is typically used in small amounts as a thickening agent, so the calorie contribution in a typical serving is minimal.

Can I eat cornstarch on a keto diet?

Cornstarch is not keto-friendly as it is very high in carbohydrates, containing 87.5 grams of carbs per 100 grams. Even small amounts can quickly exceed the daily carb limit for a ketogenic diet.

Are there any health concerns with consuming cornstarch?

Cornstarch is nutritionally poor as it lacks protein, fiber, vitamins, and minerals, consisting almost entirely of carbohydrates. Additionally, excessive consumption of cornstarch can lead to blood sugar spikes, especially for individuals with diabetes or insulin resistance.

What is the recommended serving size of cornstarch?

A typical serving size of cornstarch is 1 tablespoon, which is approximately 7-8 grams and provides around 26-30 calories. This small portion is usually enough for thickening purposes in recipes.

How does cornstarch compare to flour as a thickener?

Cornstarch is more effective as a thickener than flour because it has almost twice the thickening power. Unlike flour, cornstarch creates a translucent finish in sauces and soups rather than an opaque one. However, cornstarch cannot be substituted 1:1 with flour; typically, half the quantity of cornstarch is sufficient.
