Cornstarch and millet flour belong to the grains food group, one of the staple food groups for people on a plant-based diet.

Grains and grain products are an affordable source of carbohydrates, as well as essential vitamins and minerals, including B vitamins (such as thiamin, riboflavin, and niacin), iron, and zinc, minerals that are usually harder to get on a plant-based diet.

They also provide a small amount of protein and healthy fats.

However, it is important to note that whole grains are generally a better source of these nutrients than refined grains.

This article will thoroughly compare cornstarch and millet flour and help you learn more about their similarities and differences.


Cornstarch (Zea mays) is a type of carbohydrate derived from the endosperm of the corn kernel.

It is a good source of energy, providing a high amount of carbohydrates and small amounts of protein, vitamins, and minerals. It is pure starch and has a very low nutritional value compared to whole-grain cornmeal.

Cornstarch is commonly used as a thickening agent in cooking and baking, as it can absorb liquids and increase the viscosity of sauces, gravies, and puddings. It is also used as a coating for fried foods to provide a crisp texture. It is a gluten-free ingredient and can be used as a thickener for people with gluten sensitivity or celiac disease.

Cornstarch is typically used in small amounts and is not a significant source of nutrition in the diet. It is often used as a thickener in combination with other ingredients, and when consumed in moderation, it can be included as part of a healthy diet.

Cornstarch is not an excellent source of any particular vitamin.

Millet flour

Millet flour (Panicum miliaceum) is made from ground millet, which is an ancient grain that is grown in many parts of the world, including Africa, Asia, and Europe.

It is a good source of carbohydrates, dietary fibers, and small amounts of vitamins and minerals like magnesium, phosphorus, and B vitamins. It is also gluten-free and easy to digest, making it a great option for people with gluten sensitivities or celiac disease.

Millet flour is commonly used in baking and is a good alternative to wheat flour for gluten-free or alternative baking. It is also used in traditional African and Asian dishes.

Millet flour is considered a functional food, as it has been shown to positively impact health when consumed regularly as part of a balanced diet. It is also a sustainable crop, as it is drought-tolerant and can be grown in poor soil conditions.

Millet flour is an excellent source of Vitamin B1 (Thiamine), Vitamin B3 (Niacin), and Vitamin B5 (Pantothenic acid).

It also contains a good amount of Vitamin B6 (Pyroxidine), and Vitamin B9 (Folate) and some Vitamin B2 (Riboflavin).
