Nutrition is a vital factor in our daily activities. It is important to note that what we feed on has a great impact on our brain functionality (Haugen & Musser, 2012). A healthy balanced diet will promote a healthy brain and in return, a healthy body since the brain is the hub of all body functions. In nutrition, you can also use supplements, which enable one acquire vitamins, enzymes and amino acids that one’s body may be straining to get from foods. According to Haugen and Musser (2012), the supplements are usually in the form of capsules, gels liquids and powder.

However, it should be noted that it is much better to use natural foods as compared to the intake of supplements, which may have negative biological reactions in the body. If two or more supplements are used at the same time, medicine and supplements should apply simultaneously (Mary and Roseman, 2011). The scenario is also true in a situation where one is to undergo surgery and takes too much vitamins A, D and iron. Nutrition helps one avoid diseases such as diabetes, cancer, stroke and other cardiovascular disease and for those who want to reduce weight and manage the weight loss (Journal of Research in Medical Sciences, 2012).

In this study, the nutritionist advice on the usage of supplements and why is it that they do not give us a combination of natural foods that are contained in the supplement since it is clearly evident that some chemicals are uses in the manufacture of the supplements (Ramona Robinson-O’Brien, 2009).  There is also no 100% guarantee that the intake of specific foods will lead to a total halt of cancer formation and even its development. In essence, it is all about prevention and it is not a guaranteed prevention since one may eat healthy but other lifestyles make us ill with the same diseases we are trying to prevent.

The study design in this situation is purely experimental for example if we were to undertake a research on weight loss we would conduct various experiments like the intake of various foods at a given period of time and regular weight measurement (Journal of Research in Medical Sciences, 2012). The study population was 137. Most of the participants were women with a BMI of 34.1 bearing in mind any person with a BMI of 30 and above is considered as obese. The population had the age of 57. The inclusion and exclusion criterion was based on their BMI and their age (Haugen & Musser, 2012).

The main limitation was the fact that after the participants lost weight 64% of them gained the weight after approximately four months, getting the participants to participate willfully and follow the research requirements was a bit hectic (Haugen & Musser, 2012).  Based on the sample used the information acquired could not be generalized since the greater percentage of the population was comprised of women. Therefore, men were insufficiently represented to generalize the information. The research did not bring forth any new information but validated other research done by other scholars on the same field, neither where new questions raised from the research (Ramona Robinson-O’Brien, 2009). If I were to undertake a follow up study, I would have various hypotheses such as how natural foods can be combined to serve the same purpose like the food supplements and why should food supplements be included in nutrition.
