Nutrients that do not produce energy are minerals, vitamins, water and dietary fiber. Nutrients sustain all life activities such as reproduction, growth, development and survival of the organism and are classified into seven major nutrients, which are proteins, lipids, carbohydrates, minerals, vitamins, water and dietary fiber. Among them, protein, lipids, carbohydrates can produce energy, the remaining four nutrients do not produce energy. 1. Minerals: the physiological role of minerals is mainly composed of human tissue, participate in the body’s metabolism, to maintain physiological functions, can not be synthesized in the body, must be ingested from the outside world, will not produce energy. 2. Vitamins: there are many types of vitamins, not the body’s energy source, but can play an important role in the body’s material and energy metabolism. 3. Water: water is a body component of the material, involved in metabolism, regulation of body temperature, but also has the role of lubrication, and does not produce energy. 4. Dietary fiber: the role of dietary fiber is mainly to reduce the intestinal cholesterol absorption rate, to prevent excess energy, the human body itself can not use dietary fiber, but part of the intestinal probiotics can use dietary fiber to produce heat.
