Chemicals are essential building blocks for practically everything in the world. All living organisms – including people, animals and plants – consist of chemicals. And also all food is made up of chemical substances.
The chemicals in our food are largely harmless and often desirable – for example, nutrients such as carbohydrates, protein, fat and fibre are made up of chemical compounds. These chemicals contribute both to a rounded diet and to our eating experience. Chemicals occur naturally in the food chain and also as a result of, for example, farming, food processing and transportation.
