The article articulates that dietary fat plays a vital role in the prevention of cardiovascular diseases. Its main objective is to compare effects of long-term low fat versus high-fat diets on blood lipid levels in overweight or patients who are obese. A research was done where literature was used to support the hypothesis. The eligibility of the results was also considered. Quality assessment of the study was done using the Jadad score. Data extraction and statistical analyses were vital to ensure the credibility of the study. Observation of the characteristics of the participants also helped to come up with findings during the study. From the results of the study, low-fat diets are important in the reduction of obesity and other cardiovascular diseases. The study, however, did not consider information from unpublished data. Besides, there was heterogeneity of various aspects and characteristics of the study protocols.
The authors of the article are educated and knowledgeable individuals, with an ability to conduct serious research. This is indicated by the abbreviations (MSc), which means Masters Degree and Ph.D. that means Doctorate. The degrees possessed by the authors enhance their credibility because they are seen as individuals with high levels of education and ability to do research on any given topic. The periodical has an editorial board that plays an integral role in enhancing its credibility. The editorial board is indicated at the copyright section (Academy of Nutrition and Dietetics). The authors are affiliated to the Academy of Nutrition and Dietetics, and this enhances their credibility.
The scientific research, in this case, is being presented. The research is current as it was done in 2013, and it presents information about the reduction of obesity through consumption of low-fat diets, which is a current global issue. The research lists references that allow readers to investigate the source of information included. Full citations are also included within the research to enhance the credibility of the information presented.
The underlying hypothesis of the research is that if dietary interventions are put in place then obesity and its associated diseases, such as cardiovascular diseases will be prevented.
The article concludes that low-fat diets decrease cholesterol levels. The research recommends that people should use low fat diets. These are supported by the discussion in the research, which articulates that dietary interventions play an important role in the prevention of obesity and its associated diseases, such as cardiovascular diseases.
Additional research can also be done to test the hypothesis. The research would sample two normal men without obesity. The two men would be introduced to different diets, one on a low-fat diet and the other on a high fat diet, for a period of one month. After that period, the effect of fat on the health of the individuals will be measured. Most likely, after the period, the individual on a low-fat diet will remain healthy while that on high-fat diet will be obese.
In the article, an individual would believe the statement that diet is one of the cornerstones in the primary prevention of obesity, and its associated detrimental consequences. It is because most obese individuals and those who die from heart failure and other related complications feed on high-fat diets. However, an individual would not believe the statement that weight change represents a potential confounder in the interpretation of blood lipid levels. This is because some individuals will not gain weight by feeding on high-fat diets.
In doing further research on the article’s topic, the World Health Organization database would be a vital source. The database contains information on nutrition and the effective physical activities that help in the prevention of obesity and related cardiovascular diseases.
