Cornstarch and oats 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 oats and help you learn more about their similarities and differences.

Cornstarch

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.

Oats

Oats (Avena sativa) is a type of cereal grain grown for their edible seeds, also known as groats.

They are a good source of dietary fibers, particularly beta-glucan, which has been linked to various health benefits such as reducing cholesterol levels and improving digestion. They also provide a good source of vitamins, minerals, and antioxidants such as vitamin E, zinc, iron, and manganese.

Oats are a staple ingredient in many breakfast foods such as oatmeal, granola, and muesli. They can also be used as an ingredient in baking, added to smoothies, and used as breading for meat and fish dishes. Oat flour, made from ground oats, can also be a gluten-free alternative in baking.

Oats are also considered a functional food, as they have been shown to positively impact health when consumed regularly as part of a balanced diet.

Oats is an excellent source of Vitamin B1 (Thiamine), and Vitamin B5 (Pantothenic acid).

It also contains a good amount of Vitamin B2 (Riboflavin), and Vitamin B9 (Folate) and some Vitamin B3 (Niacin), and Vitamin B6 (Pyroxidine).

Cornstarch vs Oats Nutrition

Now that we’ve described the origin, taste, and usage of these foods, we can move to the most interesting part – comparing cornstarch vs oats.

This comparison will start by comparing the caloric value of cornstarch and oats and their macronutrients and then go more in-depth by analyzing their vitamin and mineral content.

Cornstarch vs Oats Calories

Most calories in grains come from carbs.

Comparing cornstarch vs oats for weight loss, cornstarch is slightly lower in calories, with 381 calories per 100 grams, compared to 389 calories per 100 grams of oats.

However, both cornstarch and oats can and should be a part of a healthy diet, and neither one shouldn’t be avoided if you’re looking to lose weight.

Cornstarch vs Oats Protein

Grains and most grain products, including cornstarch and oats, are important sources of plant-based protein.

However, it should be noted that most grains, with the exception of quinoa and buckwheat, for example, are low in lysine and methionine.

That said, you can combine grains with legumes to get a complete protein.

Oats offers around 98% more protein than cornstarch.

Oats has 16.9 grams of protein per 100 grams, while cornstarch has 0.3 grams of protein per 100 grams.

Cornstarch vs Oats Carbs

Counting carbs can be important for some people for different reasons, including blood sugar control, weight management, or athletic performance.

It’s also important for people on a keto diet, so let’s compare the carbs content in cornstarch and oats.

The total amount of carbohydrates is around 27% higher in cornstarch than in oats. It has 91.3 grams per 100 grams, compared to 66.3 grams in oats.

That said, 100 grams of cornstarch and oats contains 0 grams of sugar, the same amount.

Lastly, let’s take a look at the dietary fiber in cornstarch and oats.

Dietary fiber keeps the digestive system healthy and helps with weight management by promoting a sense of fullness.

With 10.6 grams of fiber per 100 grams, oats is a better source of fiber than cornstarch which offers 0.9 grams per 100 gram portion.

Cornstarch vs Oats Fats

Like most other grains, cornstarch and oats are low in fat.

Fats in cornstarch and oats are mostly healthy unsaturated fats. They are naturally cholesterol-free and trans-fat-free.

Total fat in cornstarch and oats:

  • Cornstarch: 0.1 grams per 100 grams
  • Oats: 6.9 per 100 grams

Speaking of saturated fats, cornstarch is 100% lower in saturated fats.

Cornstarch and oats contain 0 grams and 1.2 grams of saturated fat per 100 grams, respectively.

Cornstarch vs Oats Vitamins Content

This section will discuss the vitamin content of cornstarch and oats.

Vitamins are micronutrients, meaning we need only a small amount. However, they are very important for many processes in our bodies.

Cornstarch has a higher amount of vitamin B1 (Thiamine), vitamin B2 (Riboflavin), vitamin B3 (Niacin), vitamin B5 (Pantothenic acid), vitamin B6 (Pyroxidine), vitamin B9 (Folate), vitamin E, and vitamin K.

Cornstarch and oats contain the same amount of vitamin A, vitamin C, vitamin D, and vitamin B12 (Cobalamin).

The following table shows the exact amount of vitamins cornstarch and oats contain side by side, so you can easily compare them.

Cornstarch vs Oats Minerals Content

Minerals are important for our body to function properly. We need only a small amount of minerals, so they are called micronutrients.

Some minerals, like iron, calcium, zinc, or iodine, are relatively hard to get on a plant-based diet, so it’s important to choose your foods thoughtfully. This part of the cornstarch and oats comparison focuses on their mineral content.

Cornstarch is a better source of calcium, copper, iron, magnesium, manganese, phosphorus, potassium, and zinc than oats.

On the other hand, oats is a higher amount of selenium, and sodium.

Cornstarch and oats contain the same amount of fluoride.

The Final Word

This article highlighted the similarities and differences between cornstarch and oats.

Grains, also known as cereal grains, are an important source of nutrition for many people around the world. They are a rich source of carbohydrates, which provide energy for the body.

Whole grains contain important vitamins and minerals, such as B vitamins and iron. Whole grains, in particular, are high in dietary fiber and can help with digestion and weight management.

They may also have other health benefits, such as reducing the risk of heart disease, diabetes, and certain types of cancer.

Grains are also a staple food and an important source of food security in many parts of the world.
