Oat bran vs Whole-grain cornmeal: Difference & Similarities

Oat bran and whole-grain cornmeal 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 oat bran and whole-grain cornmeal and help you learn more about their similarities and differences.

Oat bran

Oat bran, a by-product of oat milling, is derived from the outer layer of the oat grain (Avena sativa).

It is a good source of dietary fibers, especially beta-glucan, vitamins, minerals, and antioxidant compounds that help to lower cholesterol, aid in digestion, and improve heart health.

Oat bran also contains a significant amount of minerals like iron, zinc, magnesium, and manganese, as well as B-vitamins like niacin, thiamin, and vitamins E and K.

It is often used as an ingredient in breakfast cereals, granolas, breads, and other baked goods, and also can be used as a thickener for soups, stews, and sauces.

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

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

Whole-grain cornmeal

Whole-grain cornmeal (Zea mays) is made by grinding whole corn kernels into a fine or coarse powder. It is considered a whole grain because it contains all three parts of the corn kernel: the germ, bran, and endosperm.

It is a good source of carbohydrates, dietary fibers, and small amounts of vitamins and minerals like vitamin B3, iron and zinc. It also contains antioxidants, such as carotenoids, flavonoids, and phenolic acids, that have been linked to various health benefits, including improved heart health and blood sugar control.

Whole-grain cornmeal is commonly used in traditional American cuisine, such as cornbread, polenta, and grits. It can also be used as a coating for fish and meats, as an ingredient in baking, and as a thickener in soups and sauces. It is a healthier option than refined cornmeal as it retains all the nutrients from the corn kernel and provides more fiber.

Whole-grain cornmeal is an excellent source of Vitamin B1 (Thiamine).

It also contains a good amount of Vitamin B2 (Riboflavin), Vitamin B3 (Niacin), and Vitamin B6 (Pyroxidine) and some Vitamin A, Vitamin B5 (Pantothenic acid), and Vitamin B9 (Folate).
