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.
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.
Tapas (Spanish pronunciation: [ˈtapas]) are a wide variety of appetizers, or snacks, in Spanish cuisine. They may be cold (such as mixed olives and cheese) or warm (such as chopitos, which are battered, fried baby squid). In select bars in Spain, tapas have evolved into an entire, and sometimes sophisticated, cuisine. In Spain, patrons of tapas can order many different tapas and combine them to make a full meal. In some Central American countries, such snacks are known as bocas.
The serving of tapas is designed to encourage conversation because people are not so focused upon eating an entire meal that is set before them. Also, in some countries it is customary for diners to stand and move about while eating tapas.
