| Abstract from DBPedia | A staple food, food staple, or simply a staple, is a food that is eaten often and in such quantities that it constitutes a dominant portion of a standard diet for a given person or group of people, supplying a large fraction of energy needs and generally forming a significant proportion of the intake of other nutrients as well. A staple food of a specific society may be eaten as often as every day or every meal, and most people live on a diet based on just a small number of food staples. Specific staples vary from place to place, but typically are inexpensive or readily available foods that supply one or more of the macronutrients and micronutrients needed for survival and health: carbohydrates, proteins, fats, minerals, and vitamins. Typical examples include tubers and roots, grains, legumes, and seeds. Among them, cereals, legumes, tubers, and roots account for about 90% of the world's food calories intake. Early agricultural civilizations valued the foods that they established as staples because, in addition to providing necessary nutrition, they generally are suitable for storage over long periods of time without decay. Such nonperishable foods are the only possible staples during seasons of shortage, such as dry seasons or cold temperate winters, against which times harvests have been stored. During seasons of plenty, wider choices of foods may be available. Staple foods are derived either from vegetables or animal products, and common staples include cereals (such as rice, wheat, maize, millet, barley, oats, rye, spelt, emmer, triticale and sorghum), starchy tubers or root vegetables (such as potatoes, cassava, sweet potatoes, yams, turnips, rutabagas or taro), meat, fish, eggs, milk, and cheese, and dried legumes such as lentils and other beans. Other staple foods include sago (derived from the pith of the sago palm tree), and fruits such as breadfruit and plantains. Staple foods may also include (depending on the region) olive oil, coconut oil, and sugar (e.g. from plantains).主食（しゅしょく）とは、副食の対義語、対比概念。日常の食事の中心になる食物。飯、麺類、パンなどのこと（大抵は穀類を調理したものの名称）。 小麦、大麦、トウモロコシ、エンバク、ライムギなどの禾穀類（かこくるい）が主食となっている国々や地域が多い（ヨーロッパ、南アメリカ・北アメリカ、中国など）が、イネが主食となっている国々や地域も少なくない（主として東南アジア）。その他に、各種豆類（大豆等）、果実類（プランテン、パンノキ）、サゴ等を主食にする人々も。だが、ノルウェーの人々のように何世紀にもわたり魚類を主食に生きてきた人々や、イヌイット（エスキモー）のように狩猟で得た生肉を主食として生きてきた人々もいる。 (Source: http://dbpedia.org/resource/Staple_food) |
