Food Types and Nutrients
Food is any substance consumed in order to provide nutrition to an organism. In humans, food is generally of animal, plant or fungi origin, and has various necessary nutrients, including proteins, carbohydrates, vitamins, or even minerals. In addition, food has the purpose of keeping the body alive and growing, and can also be used as a means of avoiding death by starvation. The word ‘food’ comes from the Greek word agron, which means to nourish, and is related to the term ‘dehydration’. Foods are categorized into different groups according to the type of food they are made from.
One example of this is seen food, which refers to substances that animals eat so that they may grow. Some plants are eaten to supply carbohydrates to the body, while some are eaten to give the body oxygen and other nutrients. Fungi are organisms that can be found in the wild or in damp forest places to provide carbohydrates to the human diet. Plants are not only eaten to provide nutrients to the body but also to supply color, scent, and sometimes taste to foods. Animals have also been domesticated in order to serve as pets, for hunting purposes, or as fighters or sport animals.
Food is divided into several groups according to their types and effects on the body. The macro-nutrient classification is made by looking at the type of nutrient that is contained in a given food, whereas the micronutrients classifies the food’s effects on the body’s systems. For example, carbohydrates can be broken down to glucose or blood sugar, and these are classified as macronutrients. Commonly used food types in the diet are carbohydrates, protein, vegetables, fruits, nuts, dairy products, fat, and fibre.
