It is often said that you are what you eat! This is an old mantra which almost everyone of us might have heard sometimes when in schools. The statement may sound a little impractical but holds really true even if you are a grown up now. Our body needs energy and some other components to perform various functions and these things are supplied from the food we eat. Therefore, it will not be impractical to say that our body will change according to what we eat. It is very important to follow regular diet courses in order to eat healthy and develop a smart diet to stay fit. We all know that living things are composed of cell which undergo cell division cycle regenerate new cells to replace the old cells. Actually these are cells that have all the necessary information of all the vital functions occurring in the body. These cells make tissues which have different turnover times and the lifespan of a tissue more or less depends on the workload endured by the cells it is composed of. The life span of cells or tissues varied from days to years. Cells obtain their energy to do all the necessary task from the complex organic molecules find in food. Major molecules which provides energy are proteins, carbohydrates and fats. This energy, which is obtained by complex process of breaking down of molecules, is utilized to perform everyday tasks by humans and is also used by cells for their division. Therefore, it is very important to eat healthy food which can provide necessary energy to body and cells. It is quite clear that whatever we eat is broken down through complex organic process to obtain energy needed by cells and body. However, it is not only the energy which we need to have in order to stay healthy and perform necessary task. For instance, human body also needs fiber to keep the metabolism regulated and unfortunately most of us fail to add this very necessary component in our diet. This is the reason why Fitness Courses are dependent on Diet Courses to provide important health components to our body. Most of the so called fitness freak people think that they will get all the nutrients from the supplements available in the market. But wouldn't it sound more sensible to get all these important vitamins, minerals and energy from natural sources rather than products made artificially in labs. These supplements often contain trisodium phosphate as an additive derived from phosphate rocks and it is also used to clean surface before painting. When people are more keen to put such kinds of substances into their body then there's no wonder why there is an abundance of health issue in modern people. A healthy diet is not what is made in labs but is what consists of legumes, meat, fruit and vegetables.
