How Food Is Made and Preserved


Food is the nutrient-rich material that people and animals consume to sustain life and promote growth. It is obtained from plants and animals that are cooked or preserved for consumption. The composition of food varies with cultural traditions and environmental conditions. A person’s diet also depends on economic and political factors, such as availability and price of foodstuffs.

The earliest humans were hunter-gatherers, eating only the food that was available in their immediate environment. With the development of agriculture and animal husbandry, humans became able to grow and store food in larger quantities. New preservation techniques allowed for the long-distance transport of foods. The Industrial Revolution brought about a rapid increase in the production of processed foods. These foods are high in calories, fat, sugar, and sodium, and may contain chemical additives.

Eating a well-balanced diet of foods from each of the main groups is important for good health. The major food groups are cereal grains; fruits and vegetables; meats, fish and poultry; dairy products; and fats and oils. A healthy diet includes at least three to five servings of each of these food groups each day.

Vegetables supply a person with vitamins and minerals. These include dark green vegetables, such as spinach and kale, tomatoes, peppers, and broccoli; legumes (beans and lentils); and root crops, such as potatoes and sweet potatoes. People can get plenty of fiber from these foods, too. They can be eaten raw or cooked, and they may be added to soups, stews, casseroles, salads, dips, and salsa.

Food can be stored for long periods of time by freezing, drying, smoking, salting, pickling and canning. It is also possible to preserve it with ultraviolet radiation or by using chemical preservatives. A large amount of energy is needed to grow and prepare food. To reduce this energy cost, some people grow their own food on farms or in gardens.

Many cultures have traditional foods that are unique to them. These foods often serve as a cultural identity. The taste of these foods can also contribute to a person’s feelings and emotions. A person can be moved by the flavor of a food, and this can make them want to eat it again.

College admissions officers know that a college essay can reveal a lot about an applicant, so writing about food in an application is a great way to show an individual’s personality. A student may write about how a family recipe or a trip to a restaurant made an impression on them. The essay may also discuss an experience with food, such as learning to eat spicy foods or dealing with an allergy.

When writing an essay about food, it is important to avoid overusing the words “taste” and “flavor.” Instead of using these words, a writer should try to describe what he or she is seeing, hearing, touching and smelling in the dish being described. Also, it is not appropriate to refer to a cuisine as exotic or strange. Doing so can have negative connotations, and it can lead to a sense of cultural imperialism.
