Bannock is a variety of flat quick bread. The word can also be applied to any large, round article baked or cooked from grain. When a round bannock is cut into wedges, the wedges are often called scones. But in Scotland, the words bannock and scone are often used interchangeably.

"Bannock" is a Scots word of Celtic origin. The Oxford English Dictionary states the term stems from panicium, a Latin word for "baked dough", or from panis, meaning bread. Its first cited use was in 1000, and its first cited definition in 1562. Its historic use was primarily in Ireland, Scotland and Northern England. The Scottish poet Robert Burns mentions the bannock in his Epistle to James Tennant of Glenconner, in reference to Alexander Tennant.

The original bannocks were heavy, flat cakes of unleavened barley or oatmeal dough formed into a round or oval shape, then cooked on a griddle (or girdle in Scots). In Scotland, before the 19th century, bannocks were cooked on a bannock stane (Scots for stone), a large, flat, rounded piece of sandstone, placed directly onto a fire, then used as a cooking surface. Most modern bannocks are made with baking powder or baking soda as a leavening agent, giving them a light and airy texture.

Bannock has more than one meaning:

Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, or stimulate growth.

Historically, people secured food through two methods: hunting and gathering, and agriculture. Today, most of the food energy consumed by the world population is supplied by the food industry.

Food safety and food security are monitored by agencies like the International Association for Food Protection, World Resources Institute, World Food Programme, Food and Agriculture Organization, and International Food Information Council. They address issues such as sustainability, biological diversity, climate change, nutritional economics, population growth, water supply, and access to food.

The right to food is a human right derived from the International Covenant on Economic, Social and Cultural Rights (ICESCR), recognizing the "right to an adequate standard of living, including adequate food", as well as the "fundamental right to be free from hunger".
