What is Cornstarch Exactly?

Cornflour or cornstarch is a highly refined form of carbohydrate. This white powdery substance is extracted from the endosperm of corn. Essentially, cornstarch is normally used as a thickening ingredient in sauces, gravies, marinades, soups and all sorts of desserts. Cornstarch is only made from corn; unlike other flours, it contains carbohydrates and no protein, making it gluten-free. Cornstarch is a multifunctional ingredient it can be used in plastics, baby powder, batteries and cosmetics.

Should You Eat Cornstarch Raw?

Even though it is possible to eat cornstarch raw, it isn’t recommended to do so. Eating cornstarch can be dangerous, because your body cannot break it down. This is because your body specialises in absorbing starch through your small intestine, where enzymes break it down into glucose or sugar molecules so that they can be used as energy. Raw starch cannot seep into your body, rather it can be digested by gut bacteria in your large intestine. The safest way to consume cornstarch, is through cooking it first, as cooked starches are safer to eat; breaking it down into glucose which will eventually allow your body to absorb and use it for energy.

What Does Cornstarch Taste Like?

Cornstarch is a white tasteless powder, that is often used to thicken soups and sauces. It provides texture rather than flavour to all sorts of dishes.

Is it Okay to Eat Cornstarch?

Raw Cornstarch vs Cooked Cornstarch

There are some advantages and disadvantages in eating raw cornstarch than cooked cornstarch. Raw cornstarch is difficult to digest, compared to its cooked form. Although raw cornstarch may result in gas or bloating, it doesn’t contribute to an increase in blood sugar levels as opposed to its cooked form.

Though it is gluten-free and is a quick source of calories, making it a possible addition to many diets.
