Throughout the history of human society, food has served as a primary means of feeding people. In addition to providing energy, food provides essential nutrients that are necessary for the growth and repair of body tissues. The amount of nutrition that people receive from their diet depends on their geographical location and their culture.
Historically, humans have secured food by hunting, gathering, and agriculture. However, improved transportation and communications has enabled more varieties of food to be accessible to people. Furthermore, modern agricultural technologies have increased the number of food products available.
Food can be animal or plant based, and can be either raw or cooked. Many of these foods are preserved by freezing, drying, or canning. Other foods have additives that improve taste, consistency, or texture. Some ingredients are natural, but others can be manufactured more economically.

Traditionally, meat is a major source of protein. Several types of meat, including beef, yak, and bison are commonly eaten. Fish and poultry are also sources of protein. Animal fats such as lard and butter are also common. These fats help protect internal organs.
People also eat fruits. Most botanists define fruit as part of a perennial plant that contains seeds. Fruits are a source of vitamins and minerals. Among fruits, some of the most nutritious are bananas, apples, and kiwifruit. A few other fruits are oranges, lemons, and grapes.
Meats include lamb, beef, and hogs. Lamb is a popular food in the United Kingdom and Australia. Another meat source is camels. Beef and hogs are raised in the United States and the European Union. Chickens and geese are a popular food in many other countries.
Many cultures have diverse cuisines, but they share similarities in their food preparation and cultural preferences. While some cultures are focused on producing high-quality, healthy food, others have poor diets. This phenomenon is called malnutrition. It is especially prevalent in developing nations.
Food is an important factor in globalization. Since food can be harvested and processed far from where the food originated, more foods have been made available to people. Additionally, the increased availability of food has encouraged the development of new ingredients.
The FDA estimates there are about 44,000 food processors in the U.S. Those manufacturers are responsible for producing and processing various types of food. They can include producers, canners, and wineries. There are also dozens of other food and beverage companies that are involved in this industry.
Because most people in the developed world are able to afford nutritious food, their diets tend to be too low in fruits and vegetables. However, they can also have an overly high intake of refined sugars and fats.
Food regulation is a process that outlines safety standards for various products. Currently, the USDA Food Patterns specify targets for each food group in cup equivalents. For example, the Food Patterns suggest a limit on calories (8-19%) and saturated fats (less than 10%).
Food can be either animal or plant-based. In addition to protein, food also provides nutrients, such as carbohydrates, fats, and fiber.
