Important: These guidelines must be followed; otherwise points earned will be a zero.

Overview:

• Typed research paper of 5 – 6 pages (12 pt font, double spaced) on an appropriate nutrition topic approved by instructor.
• One page from each of the required five research-based references must accompany the paper (Upload into Canvas Lab 3 Report assignment submission box).
• Use the IFIC Review document for background reading on understanding and interpreting food and health research (see course website).
• APA style guidelines must be used in citing research articles (see course website).
• Visit to TMCC Writing center is required – NOTE: MAKE APPOINTMENT WAY AHEAD BECAUSE THEY ARE VERY BUSY. Provide a copy of email from tutor stating what session was about. (Upload into Canvas Lab 3 Report assignment submission box)

Construction:

• Introduction: Includes background information pertinent to your topic, an overview, which is a brief description of what you will be discussing in the body of the paper, and a hypothesis, which was discussed in Lab 1. (Possible 20 points)

Information to include in paragraph form:

• The Different types of Carbohydrates.

• How enzymes are used in digestion.
• How the body digests mono and disaccharides versus oligosaccharides: which enzymes are used and what are the products of digestion for both.

• Importance of Fiber, the RDI, types and and foods high in both.

• Why are glucose levels measured and how?
• How much gas does our body produce daily?
• Research and name several digestive aid supplements on the market and pick at least two to compare and contrast based on the research.
• Form a question about which one you think will be most effective in aiding oligosaccharide digestion.
• Form a hypothesis stating which one of the two works better on oligosaccharide digestion based on research.
• Briefly explain why you chose this hypothesis.

• Methods: Methods used in the research studies including: type of research conducted and procedures followed, how many participants there were, when the studies were conducted, by whom, and how long the studies lasted. (10 points)
• Results: Present all data using a self-constructed graph or graphs- they must be typed and include titles and a key adequately portraying the results found between the different supplements based on the research (Possible 10 points)

• Discussion: Represents the presentation of your findings in a logical order with an explanation of source and relevance to the hypothesis statement. Five original peer-reviewed research or review articles should be summarized to support the research statement.  Define any scientific terms in the paper. At least 4 terms should be defined throughout the paper. Here is where you will compare and contrast the two. (Possible 15 points)

Information to include in paragraph form:

• The supplements chosen and their ingredients.
• How they differ and how each works in the body.
• How long they have been on the market and/or used for digestive purposes and efficacy of each.
• Safety and side effects of each.

• Summary: Summarize the findings with answers or responses to the hypothesis statement. (Possible 15 points)

Information to include in paragraph form:

• Your interpretations of the data that you obtained from the research. DO NOT simply restate the information, interpret it, using the data found.
• Hypothesis restated.
• Do the data support your hypothesis? Why or why not?
• What does your data tell you about the effectiveness of the supplements?
• Were there any limitations and/or bias in the research? Why or why not?
• Any suggestions for further study?

References and Readability: You are to use and cite AT LEAST 5 references from original/review research articles from peer reviewed journals in APA format. References are to be cited within the paper and as a separate Reference Page. Virtual visit to the writing center is also required.  (Possible 10 points)

Peer Reviewed journals include:

• The Journal of Nutrition
• The American Journal of Clinical Nutrition

GUIDELINES FOR AVOIDING PLAGIARISM

Plagiarism is the unauthorized use or close imitation of the language and thoughts of another author and the representation of them as one’s own original work. Unlike cases of forgery, in which the authenticity of the writing, document, or some other kind of object, itself is in question, plagiarism is concerned with the issue of false attribution.

Within academia, plagiarism by students, professors, or researchers is considered academic dishonesty or academic fraud and offenders are subject to academic censure. In journalism, plagiarism is considered a breach of journalistic ethics, and reporters caught plagiarizing typically face disciplinary measures ranging from suspension to termination. Some individuals caught plagiarizing in academic or journalistic contexts claim that they plagiarized unintentionally, by failing to include quotations or give the appropriate citation. While plagiarism in scholarship and journalism has a centuries-old history, the development of the Internet, where articles appear as electronic text, has made the physical act of copying the work of others much easier.

Plagiarism is different from copyright infringement. Where both terms are appropriate, they emphasize different aspects of the transgression. Copyright infringement is a violation of the rights of the copyright holder, which involves the loss of income and artistic control of the material when it is used without the copyright holder’s consent. On the other hand, plagiarism is concerned with the unearned increment to the plagiarizing author’s reputation. (http://en.wikipedia.org/wiki/Plagiarism)

KEY POINTS:

• Use your own words and ideas
• Give credit for paraphrased material in the form of a reference citation
• When in doubt, cite another person’s work. It is better to be safe than not give credit when you should.

Reference example in paper:
In a recent epidemiological study, overweight young women were shown to have higher LDL and lower HDL cholesterol levels than normal weight women (Graham, Beall, Lussier, McLaughlin & Zidenberg-Cherr, 2005).
