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.
The oat grains are de-husked by impact, then heated and cooled to stabilize the “Oat groats”, the seed inside the husk. The process of heating produces a nutty flavour to the oats.These oat groats may be milled to produce fine, medium or coarse oatmeal. Rolled oats are steamed and flattened whole oat groats. Steel cut oats may be small and broken groats from the de-husking process, these may be steamed and flattened to produce smaller 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 flavouring added. 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. In some countries rolled oats are eaten raw with milk and sugar or raisins. Oatmeal is also used as a thickening agent in savoury Arabic/Egyptian thick meat plus vegetable soups.
Breakfast cereal health benefits
There has been increasing interest in oatmeal in recent years because of its health benefits. Daily consumption of a bowl of oatmeal can lower blood cholesterol, because of its soluble fibre content. After it was reported that oats can help lower cholesterol, an “oat bran craze” swept the U.S. in the late 1980s, peaking in 1989. The food craze was short-lived and faded by the early 1990s. The popularity of oatmeal and other oat products increased again 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 long been a staple of many athletes’ diets, especially weight trainers; given oatmeal’s high content of complex carbohydrates and water-soluble fibre that encourages slow digestion and stabilizes blood-glucose levels. Oatmeal porridge also contains more B vitamins and calories than other kinds of porridges.
