Diet and Heart Disease

In exploring the impact of diet on heart disease it will be important to consider the theoretical perspective of the health belief model (HBM) which is the most commonly used model in health promotion and education. The HBM claims that health behavior is determined by personal beliefs about the disease and the specifics surrounding prevention and treatment (Glanz, Lewis, & Rimer, 1997). The four facets of this model involve this personal perception and include perceived seriousness, perceived susceptibility, perceived benefits, and perceived barriers (Glanz, Lewis, & Rimer, 1997). This theory will be integral in exploring the relationship between diet and heart disease as it will allow the researcher to not only explore the medical aspects but also the role of the individual in diet and heart related care.

Article 1: Dietary restriction and fibre supplementation: oxidative stress and metabolic shifting for cardiac health

Objective of the Article

This article is based on the premise that the first course of action in the prevention of heart disease is dietary modification. This study seeks to identify if there is a correlation between consuming a diet enriched in fiber and oxidative stress in cardiac tissue. Previous studies have shown that dietary fiber has been integrated into dietary programs as a manner by which glucose serum and cholesterol can be lowered (Diniz et al., 2003). Yet the impact of dietary fiber on functioning, as well as, the effect of fiber enriched eating on oxidative stress in cardiac tissue has not been fully explored through research and therefore are the focus of the current s

Methodology Employed

Researchers utilized 40 male Wistar rats which were randomly divided into groups by random computer sampling. Each group of rats was fed different diets depending on their grouping: control, fiber enriched diet, and the dietary restricted. While all diets provided sufficient nutritional values they differed in their amount and concentration of fiber. Results were measured through the obtainment of body mass each week and at week 6 the rats were fasted and sacrificed (Diniz et al., 2003). The body of the rat was then studied to determine what impact if any the introduction of dietary fiber had on heart disease, particularly oxidative stress.

Conclusions of the Study

The results of this study showed that the rats with fiber added to their diet had increased body mass. Researchers were able to identify a direct link between dietary fiber and metabolic responses (Diniz et al., 2003). In fact, these results were more significant than that of food consumption alone. In terms of cardiac functioning, dietary fiber was found to increase glycogen concentrations which increases cardiac viability. Further, dietary fiber was found to stop the development of oxidative disease in the cardiac tissues (Diniz et al., 2003).

Article 2: Dietary iron as a risk factor for myocardial infarction:

Public health considerations for Nova Scotia

Objective of the Article

The present study seeks to determine if the amount of dietary iron can result in myocardial injury. Many recent studies have indicated that higher stored iron in the body can increase the incidence of heart disease. This risk was increased when combined with high levels of cholesterol intake and are also confounded by diabetes, hypertension, and smoking (Malaviarachchi et al., 2002). Malaviarachchi et al. (2002) sought to confirm the findings of these previous studies with a particular focus on the impact of dietary iron and hemeiron on the risk of myocardial infarction while ruling out lifestyle and other health risk factors.

Methodology Employed

Malaviarachchi et al. (2002) identified 3684 non-institutionalized individuals between the ages of 18 and 74 whose demographics were spread evenly across age, sex, and county. The Nova Scotia Nutrition Survey was administered to participants via a face-to-face interview as well as a 24-hour recall of dietary intake questionnaire. Participants were also asked to complete a modified food frequency questionnaire and were asked questions regarding their demographics, socioeconomic status, and health risk factors (Malaviarachchi et al., 2002).

Macro and micronutrients in these individuals' diets were calculated using the Canadian Dietary… READ MORE

IMPORTANT: Please keep in mind that this is a Session Long Project (SLP) - One of FIVE assignments; each assignment builds onto each other. Please follow instructions carefully as I will need to order the other FOUR assignments to complete the SLP.

Please write SLP paper on *****"DIET AND HEART DISEASE*****"

SLP 1 of 5 Assignment Instructions

The session long project is designed to help you incorporate the tools and learning objectives of this course to produce a high quality research paper that includes analytical and scientific review of journal articles pertaining to the topic of choice and to formulate research principles and ideas based on the continuous research throughout the session.

For this module:

1. The first step in this process is to identify a public health topic (governed by public health policy) that you would like to learn more about. If you have read research articles or texts on this topic already, feel free to list the titles and authors along with a brief description of why this topic is important.

2. The topic must be relevant and current. Your topic must reflect AN ASSOCIATION, A RELATIONSHIP, containing at least 2 core concepts (e.g. poverty and health, war and health, health education and AIDS, diet and heart disease, aging and health care, gun control and crime rate, managed care and health outcomes, physical activity and well-being, health policy and smoking, a certain drug and its effects etc.) and possibly leading to a feasible new study. It is important that your topic is of interest both for the research community and for the public, and that it has practical implications. It is also important that the research question under study is not fully answered, that there are still aspects to explore (e.g. other populations, other components).

3. Find three scientific journal articles from ProQuest using key terms, author names etc. Important: Please do not use general internet searches and do not give websites as references. Please do not use newspaper articles or other types of lay secondary reports. The sources for the articles have to be peer-reviewed scientific journals (for example JAMA, New England Journal of Medicine, American Journal of Public Health etc).

MODULE 1 SLP ASSIGNMENT:

1. Summarize the theory on the association of interest as it is reflected in these 3 studies.

2. Address each journal article separately and state for each article:

3. What is the objective of the study?

4. What is the methodology employed?

5. What are the conclusions of the study?

6. The paper should then discuss if the findings are consistent among the 3 studies and determine if the associations in the studies appear to be causal.

SLP Assignment Expections:

1. Use information from modular background readings as well as any good quality (peer-reviewed journal articles) resource you can find. Please cite all sources and provide a reference list at the end of your paper using the APA format.

2. Length: 3-4 typed double-spaced pages

3. Format: Divide the paper into 4 sections:

a) Section 1 discusses Article 1 using questions 3-5 of the MODULE 1 SLP Assignment as subheadings.

b) Section 2 discusses Article 2 using questions 3-5 of the MODULE 1 SLP Assignment as subheadings

c) Section 3 discusses Article 3 using questions 3-5 of the MODULE 1 SLP Assignment as subheadings

d) Section 4 discusses the type of association found in the studies

4. The following items will be assessed in particular:

a) Understanding and interpretation of the objectives and conclusions of a scientific journal article

b) Discussion of causal and non-causal association.
