Food

Food is any substance normally eaten or drunk by living things. The term food also includes liquid drinks. Food is the main source of energy and of nutrition for animals, and is usually of animal or plant origin.

The study of food is called food science. In English, the term food is often used metaphorically or figuratively, as in food for thought.

Historical development

Humans are omnivorous animals that can consume both plant and animal products. We changed from gatherers to hunter gatherers. After the experience of the Ice Age it is probable that humans wanted to create some feeling of security by controlling what plants were growing and which animals were available. This led to agriculture, which has continually improved and altered the way in which food is obtained.

Meals

The number of meals in a day, their size, composition, when and how they are prepared and eaten vary greatly around the world. This is greatly dependent on the local climate, ecology, economy, cultural traditions and industrialisation. Meals also plays an important role in the celebration of many key cultural and religious festivals.

In societies where the availability of food has risen above subsistence levels and beyond staple foods, food is also sold pre-prepared for immediate consumption in restaurants and other similar retail premises. In industrial societies, meals often contain a higher proportion of food of animal origin.

In the modern era, in developed nations, food supply is increasingly dependent upon agriculture, industrial farming and fish farming techniques which aim to maximise the amount of food produced, whilst minimising the cost. These include a reliance on mechanised tools which have been developed, from the threshing machine, seed drill, through to the tractor and combine harvester, etc. These have been combined with the use of pesticides to promote high crop yields and combat those insects or mammals which reduce yield.

More recently, there has been a growing trend towards more Sustainable agricultural practices. This approach - which is partly fuelled by consumer demand - encourages biodiversity, local self-reliance and Organic farming methods.

Major influences on food production are international policy, e.g. the World Trade Organization and Common Agricultural Policy, national government policy or law and war.

Food for livestock is fodder and traditionally comprises hay or grain.

At the start of the 21st century, a two-tier structure has arisen, with a few international food processing giants controlling a wide range of well known food brands; with a populous number of small local or national food processing companies.

In 1994 trade liberalisation began when over 100 countries became signatories to the Uruguay Round of the General Agreement on Tariffs and Trade which included an agreement to reduce subsidies paid to farmers. This is underpinned by the WTO enforcement of agricultural subsidy, tariffs, import quotas and settlement of trade disputes that cannot be bilaterally resolved. Where trade barriers are raised on the disputed grounds of public health and safety, the WTO refer the dispute to the Codex Alimentarius Commission, which was founded in 1962 by the United Nations Source | Copyright
