Metabolism is the chemical process of transforming food into fuel. Metabolism is closely linked to nutrition and the availability of nutrients. Food provides a variety of substances that are essential for the building, upkeep, and repair of body tissues, and for the efficient functioning of the body. This book provides thorough coverage of the processes involved in metabolism and nutrition.
Metabolism is the chemical process your body uses to transform the food you eat into the fuel that keeps you alive. Nutrition (food) consists of proteins, carbohydrates, and fats. These substances are broken down by enzymes in your digestive system, and then carried to the cells where they can be used as fuel. Your body either uses these substances immediately, or stores them in the liver, body fat, and muscle tissues for later use. Metabolism is closely linked to nutrition and the availability of nutrients. Bioenergetics is a term which describes the biochemical or metabolic pathways by which the cell ultimately obtains energy. Energy formation is one of the vital components of metabolism. Nutrition is the key to metabolism. The pathways of metabolism rely upon nutrients that they breakdown in order to produce energy. This energy in turn is required by the body to synthesize new proteins, nucleic acids, etc. Nutrients in relation to metabolism encompass bodily requirement for various substances, individual functions in body, amount needed, level below which poor health results etc. Essential nutrients supply energy (calories) and supply the necessary chemicals which the body itself cannot synthesize. Food provides a variety of substances that are essential for the building, upkeep, and repair of body tissues, and for the efficient functioning of the body. The diet needs essential nutrients like carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, and around 20 other inorganic elements. The major elements are supplied in carbohydrates, lipids, and protein. In addition, vitamins, minerals and water are necessary. Carbohydrates are the energy powerhouses in the body. They are pulled from the starches and sugars and cellulose we eat in our foods daily. Our metabolism will break down these nutrients and supply what we need for the day. People generally only consume around half of the daily need for these compounds. They are generally consumed from foods such as bread, cereal, rice, pasta, potatoes and wheat. Glucose is the main source of energy which is formed from metabolized starches and sugars combined. This takes place post-digestion. Proteins are what we need to build muscle and tissues. Proteins are an integral part of each cell in the human body. It is a life giving substance by which hemoglobin is formed. This is just as important as blood. Fat produces twice the energy than proteins or carbohydrates. Fat is essential in its healthy forms. It helps to produce cell structure, it protects the vital organs with a cushion, the fat soluble vitamins we take are absorbed through fats and fat will create storage for energy when we need it. Minerals are responsible for the regulation of bodily functions. The minerals found in food are not used for energy in a direct sense but they play an important role in metabolic processes.
