Oatmeal is ground oat groats (i.e. oat-meal, cf. cornmeal, peasemeal, etc.), or a porridge made from oats (also called oatmeal cereal or stirabout, in Ireland). Oatmeal can also be ground oat, steel-cut oats, crushed oats, or rolled oats.

Oat groats are coarsely ground to make oatmeal, or cut into small pieces to make steel-cut oats, or first steamed and then flattened to make rolled oats. Quick-cooking rolled oats (quick oats) are cut into small pieces before being steamed and rolled. Instant oatmeal is pre-cooked and dried, usually with sweetener and flavoring added.[1] Both types of rolled oats may be eaten uncooked as in Muesli or may be cooked to make porridge. It is also used as an ingredient in oatmeal cookies and oat cakes, or as an accent, as in the topping on many oat bran breads and the coating on Caboc cheese. Oatmeal is also sometimes porridge with the bran or fibrous husk as well as the oat kernel or groat.[2] In some countries rolled oats are eaten raw with milk and sugar or raisins.
There has been increasing interest in oatmeal in recent years due to its health benefits. Daily consumption of a bowl of oatmeal can lower blood cholesterol, due to its soluble fiber content.[3] After reports found that oats can help lower cholesterol, an "oat bran craze"[4][5] swept the U.S. in the late 1980s, peaking in 1989. The food fad was short-lived and faded by the early 1990s. The popularity of oatmeal and other oat products again increased after the January 1997 decision by the Food and Drug Administration that food with a lot of oat bran or rolled oats can carry a label claiming it may reduce the risk of heart disease, when combined with a low-fat diet. This is because of the beta-glucan in the oats. Rolled oats have also long been a staple of many athletes' diets, especially weight trainers; given oatmeal's high content of complex carbohydrates and water-soluble fiber which encourages slow digestion and stabilizes blood-glucose levels. Oatmeal porridge also contains more B vitamins and calories than other kinds of porridges.[6]
Oatmeal has a long history in Scottish culinary traditions because oats are better suited than wheat to the short, wet growing season. Therefore, it became the staple grain of that country. The Ancient universities of Scotland had a holiday called Meal Monday, to permit students to return to their farms and collect more oats for food.
Samuel Johnson referred, disparagingly, to this in his dictionary definition for oats: "A grain, which in England is generally given to horses, but in Scotland supports the people." His biographer, James Boswell, noted that Lord Elibank was said by Sir Walter Scott to have retorted, "Yes, and where else will you see such horses and such men?"[7]
A common method of cooking oatmeal in Scotland is to soak it overnight in salted water and cook on a low heat in the morning for a few minutes until the mixture thickens.
In Scotland, oatmeal is created by grinding oats into a coarse powder. Various grades are available depending on the thoroughness of the grinding, including Coarse, Pin(head) and Fine oatmeal. The main uses are:
The Swiss prepare a cold oatmeal called Muesli as a breakfast cereal based on uncooked rolled oats, fruit and nuts. The oats are combined with milk, honey and spices (e.g. cinnamon), mixed and soaked in the refrigerator overnight. In the morning before eating nuts and fruit are added, the dish is not cooked.
In the U.S. state of Vermont oatmeal making has a long tradition originating with the Scottish settlement of the state. While there are variations, most begin with heavy steel cut oats. The oats are soaked overnight in cold water, salt, and maple syrup. Early the next morning, before beginning farm chores the cook will add ground nutmeg, ground cinnamon, and sometimes ground ginger. The pot is placed over heat and cooks for upwards of 90 minutes, being served after the chores with cream, milk, or butter. As most contemporary Vermonters no longer have farm chores, the recipe is simplified to a briefer 10 to 30 minute cooking at a higher heat. Vermont leads the U.S. in per capita consumption of cooked oatmeal cereal.[10] Another style found in Vermont is served at some older ski lodges, starting with heavy steel cut oats and topping it with maple syrup and vanilla ice cream, to contrast the hot temperature of the oatmeal.
