Oat bran and semolina 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 semolina 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.


Semolina (Triticum durum) is a coarse, granular flour that is made from the hard durum wheat, a type of wheat that is high in gluten and protein.

It is a good source of carbohydrates, protein, and small amounts of minerals like iron and zinc. It is also rich in B vitamins such as niacin and thiamin.

Semolina is commonly used in the production of pasta and other traditional Italian dishes like couscous and gnocchi. It is also used in some breads, pastries, and other baked goods. It gives pasta a distinct texture and yellow color due to the presence of carotenoids in the wheat endosperm.

Semolina is gluten-rich, thus, it is not suitable for people with gluten sensitivities or celiac disease. Semolina can be enjoyed in moderate portions as part of a balanced diet, combined with vegetables, lean protein sources, and healthy fats.

Semolina is not an excellent source of any particular vitamin.

However, it also contains a good amount of Vitamin B1 (Thiamine), Vitamin B3 (Niacin), Vitamin B5 (Pantothenic acid), and Vitamin B9 (Folate) and some Vitamin B2 (Riboflavin), and Vitamin B6 (Pyroxidine).
