Brown rice and buckwheat 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 brown rice and buckwheat flour and help you learn more about their similarities and differences.

Brown rice

Brown rice (Oryza sativa) is a whole-grain rice that is minimally processed, retaining its nutrient-rich bran and germ layers.

It is a good source of carbohydrates, dietary fibers, vitamins, minerals, and antioxidants. It is particularly high in vitamins B3, B1, B6, and B9 and minerals like manganese, magnesium, and phosphorus. The high fiber content of brown rice has been linked to improved digestion, weight management, and lower cholesterol levels.
