Then, what nutrients are needed by the body? Here’s the full explanation.
Nutrients Are Substances Needed by the Body
The definition of nutrition in detail is explained in the book entitled Nutritional Status Assessment written by Supariasa (2001). The book states that nutrition is a process by which organisms use food that is consumed normally. The method is through the process of digestion, absorption, transportation, storage, metabolism and excretion of substances that are not used. These things are useful for maintaining life, growth, normal function of organs, and producing energy.
Of course, nutrients or food substances have functions that are needed by the body. According to the book entitled Sports Nutrition written by Syafrizar and Wilda Welis (2009), there are three main functions of nutrients that are also used for food grouping in general, among others:
These three functions are usually referred to as the food triguna. Kartasapoetra and Marsetyo in their book entitled Nutrition Science: Correlation of Nutrition, Health, and Work Productivity (2003: 24) describes examples of nutrients based on their functions, namely:
1. As an energy substance, for example carbohydrates and fats
2. As a building substance, for example protein
3 As a regulatory substance, for example vitamins and minerals
Carbohydrates are substances composed of carbon (C), hydrogen (H), and oxygen (O) atoms. Carbohydrates play a role in producing the main energy in the body.
Protein is found in many animal foods such as beef, chicken, fish, shrimp, liver, and eggs.
Fat is broadly divided into two. First, which is a solid at room temperature or referred to as fat / fat. Second, fats are liquid at room temperature otherwise known as oils.
Vitamins are complex organic compounds that the body needs in small amounts. Although few, vitamins are very important for the process of growth, body defense, to normal metabolic processes.
