The definition of food is a term that refers to all edible materials that are used to feed living organisms. The term food refers to all edible raw materials and includes many diverse foods and food groups. The food industry comprises a vast array of services and products such as packaging, transportation, preparation of foodstuffs, production of foodstuffs, processing, sale, and distribution of foodstuffs, processing, and sale of ready-made foods, food products, beverages, confectionery, snacks, beverages, and the like.
Food is defined as any material eaten to provide nutrition to an organism. Food is normally of vegetable, animal, fungal, or microbial origin, and contains necessary nutrients, including vitamins, minerals, carbohydrates, proteins, lipids, and fats. It is not possible to eat enough food to provide the adequate nutrition needed for the body. People therefore use foods to meet the basic requirements of their bodies. This process includes processing, preservation, transportation, consumption, storage, and sales of foodstuffs.
Humans have been consuming food in some form since prehistoric times. Ancient Egyptian mummies are well known for their extensive collection of foodstuffs. Early man was probably the first to cook food, and it was then that he began to consider the need for foodstuffs. Early man was likely a hunter/gatherer who hunted wild animals and gathered fruits and vegetables from the garden. He also ate fish, milk, honey, nuts, and seeds, but these foods were likely not well digested. For this reason, these early people cooked the food they ate. They then spread the cooked food on the ground where it was consumed by others.
Humans have become dependent on food since they began farming. Farming has increased the food supplies needed to feed the expanding population. However, the increasing demand has led to a rise in the prices of food, which has resulted in people purchasing foodstuff, especially in times of scarcity. Some people have turned to the production of processed foods and packaged foods in order to meet the increased demand.
The food industry is one of the most important sectors of the modern world economy, accounting for over $600 billion in annual sales. The production and processing of foods require an enormous amount of energy and water, both of which are scarce resources. Therefore, the food industry also contributes to the pollution of water.
Human food is an integral part of the diet and is one of the most important ingredients in the formulation of medicines. In fact, the term “medicine” itself is derived from the word ‘medica’. Some common medicines that contain human food components include: vitamins, antibiotics, cholesterol, hormones, antibiotics, antifungals, laxatives, analgesics and other medications. Foods contribute to the overall health of human beings by regulating the body’s systems and by providing nutrients for the maintenance and growth of our cells. The consumption of foods also helps to repair our cells after a period of damage caused by external factors.
