Nutrition is a process in which an animal, human or plant takes in and uses food materials. Normally, in humans 85% of daily energy consumption comes from fats and carbohydrates and 15% from proteins. In humans, nutrition is absorbed through the process of bringing food into the mouth, chewing it, and swallowing it. The necessary amount of essential nutrients always varies based on the age and physical state of the person. Say no to plagiarism.

Get an original essay The Dietary Supplement Health and Education Act (DSHEA) of 1994 shows a wide variety of dietary supplements that became available first in the United States and then later throughout the world and is federal legislation that defines and regulates supplements food. A dietary supplement includes one or more of the following ingredients: multivitamin, mineral, herb, amino acid, concentrate, metabolite, l-arginine, . Examples of these compounds include creatine monohydrate, protein or carbohydrate bars, protein shakes and bars, and glutamine which are essential for body growth when the person exercises in the gym (J. Morrison et al. 2015). The importance of basic food supplements, which provide the basic diet with additional nutrients, has increased exponentially globally; therefore, numerous studies on this topic have been reported not only in a particular country but have also included countries such as India and European countries. Many of these studies have focused on young and elderly populations and on patients, who often take food supplements and medications at the same time. It was also reported that the importance of dietary supplement use among school children aged 8 to 12 years ranged from 8.0% to 15.5% in India, which is still much lower than that of United States. Children in India are given nutritional supplements by their parents during the growth phase, mainly because Indian parents believe that their children will not receive or get enough nutrients from their diet as things are not so pure nowadays. In India, parents not only give their children vitamin and mineral supplements, but also herbs or other nutrients. (Sato et al.) There is a lot of serious information that athletes, their coaches, and parents should know before giving supplements to their students and children. They should also have proper knowledge before giving dietary supplements to anyone. (Gayer et al.) (2004). In 2002, out of nearly 600 supplements purchased from 13 different countries from approximately 200 different suppliers around the world, approximately 11-15% of the total supplements were shown to contain harmful non-hormonal nutritional supplements and were clearly filled with dangerous steroids. The composition and concentration of the product from which it is made may also differ from the definitions provided on the label. Positive and positive supplements have shown that the concentration of anabolic androgenic steroids contains from 0.01 micrograms up to 190 micrograms. (Gayer et al. 2008) People who regularly go to the gym may use particular supplements for various types of reasons. There will automatically be differences in your choice of supplement based on various factors such as age, gender or reason for exercising. It is important to determine which supplements people who exercise take, why they take them, and their sources of information to help health care providers educate this population. Some people may learn about supplements from non-sources).
