What is Oatmeal?

Oatmeal is prepared from oats, a type of cereal grain. Its botanical name is Avena sativa. Oatmeal is prepared by rolling, crushing, or grinding oats into a coarse powder.

Oatcake or oat bread is also eaten for breakfast or dinner, while oats are also used in the preparation of beverages. Oatmeal is popular today because of its numerous health benefits.

Oats have been known to man since the Bronze Age. Oats grow in cooler, moister regions of the temperate zones. They have a lower summer heat requirement and greater tolerance of rain compared to other cereals such as wheat and barley, which is why they are extensively grown in Europe and North America. Oats were mass-grown from the 18th and 19th centuries, and are particularly popular in Scotland, where historians have recorded many instances of oats being a part of the Scottish culture. As oats were very cheap, easy to grow, and process, people started consuming them like cereal. [1]

  • Steel Cut Oats and Rolled Oats: These are described as one of the best types of oats. The reason? Steel-cut oats are whole grain, and they possess vital nutrients such as B-complex vitamins, protein, calcium, and fiber. These are also low in sodium and fats. Steel-cut oats and rolled oats are less closer to their natural form, making them the healthiest types of oats.

  • Instant Oats: Another consideration is the time that you are willing to spend in cooking your oats. Semi-processed oats take only about 10 to 15 minutes to cook, whereas unprocessed oats might take 20 to 30 minutes to cook. Instant oats can also be cooked using a microwave in just a few minutes!
