Food is any material consumed in order to provide nutrition to an organisms. This food is generally of animal, plant or even fungal origin, and consists of necessary nutrients, including proteins, carbohydrates, vitamins, or other minerals. A wide range of food is available in nature, although man has invented a wide variety of food, designed to our taste and convenience. Plants and animals have invented many varieties of food to meet the needs of man.
One of the main sources of food, which all other types of food must be derived from, are carbohydrates. Carbohydrates are found in many foods, including breads, cereals, pasta and potatoes. They are used in order to give the body energy, which it needs in order to carry on with its day-to-day functions. The main sources of carbohydrates are bread and cereals, whereas legumes and vegetables are the main sources of proteins.
Another type of food that you should consider in your diet is the fibre content. The best sources of fibre are cereals and fresh fruit and vegetables. The reason behind this is that fibre provides complex carbohydrates that can help the body to burn more calories, especially if they are taken in the form of whole grain bread. Other important sources of fibre are nuts, beans and whole grains. These food sources contain a large number of nutrients including minerals, antioxidants and vitamins, which are important for the body in its fight against diseases, as well as in providing energy for daily activities.
