Porridge is a food made by heating or boiling ground, crushed or chopped starchy plants, typically grain, in milk or water. It is often cooked or served with added flavourings such as sugar, honey, (dried) fruit or syrup to make a sweet cereal, or it can be mixed with spices, meat or vegetables to make a savoury dish. It is usually served hot in a bowl, depending on its consistency. Oat porridge, or oatmeal, is one of the most common types of porridge. Gruel is a thinner version of porridge. Type of grains The term "porridge" is often used specifically for oat porridge (oatmeal), which is typically eaten for breakfast with salt, sugar, fruit, milk, cream or butter and sometimes other flavourings. Oat porridge is also sold in ready-made or partly cooked form as an instant breakfast. Other grains used for porridge include rice, wheat, barley, corn, triticale and buckwheat.

Health effect A 2014 review found that daily intake of at least 3 grams of oat beta-glucan lowers total and low-density lipoprotein cholesterol levels by 5–10% in people with normal or elevated blood cholesterol levels. Beta-glucan lowers cholesterol by inhibiting cholesterol production, although cholesterol reduction is greater in people with higher total cholesterol and LDL cholesterol in their blood. In the United States, the Food and Drug Administration issued a final ruling in 2015 stating that food companies can make health claims on food labels for products containing soluble fiber from whole oats (oat bran, oat flour and rolled oats), noting that 3.0 grams of soluble fiber daily from these foods may reduce the risk of heart disease. To qualify for the health claim, the food that contains the oats must provide at least 0.75 grams of soluble
