Course Objectives:

On completion of this course, the student is expected to be able to:

1. Recognize the general chemical structure(s)/characteristics of nutritionally significant vitamins and minerals.

2. Describe the functional role(s) performed by specific vitamins and minerals in cellular metabolism/tissue function.

3. Identify factors influencing the physiological requirements for specific vitamins and minerals.

4. Identify the scientific basis for establishing quantitative dietary recommendations for specific vitamins and minerals.

5. Identify the metabolic/physiologic/nutritional consequences of a) inadequate amounts of specific vitamins and minerals and b) excessive amounts of specific vitamins and minerals.

6. Identify significant examples of nutrient interactions as illustrated by specific vitamins and minerals.

Other Additional Objectives:

1. Identify relevant chemical properties of vitamins and minerals related to stability and/or biological activity.

2. Identify typical distribution of specific vitamins and minerals in body/body tissues.

3. Identify important/major food sources of specific vitamins and minerals.

4. Identify typical occurrence/distribution of specific vitamins and minerals in the U.S. food supply and in the diets of population sub-groups (e.g. infants/children; adolescent females/males; adult females/males; pregnant/lactating women; the elderly).

5. Define and distinguish between requirements, Dietary Reference Intakes (DRI), Recommended Dietary Allowances (RDAs), Adequate Intakes (AI), Estimated Safe and Adequate Daily Dietary Intakes (ESADDIs), and Daily Reference Values (DRVs) as applied to specific vitamins and minerals.

6. Recognize, evaluate and utilize primary research reports in the scientific literature as the foundation/support for critical analysis of the expanding knowledge base related to vitamins and minerals in human nutrition.

Attendance:

Class attendance is required. Attendance sheets will be distributed on a regular basis. Being late or leaving early without proper reason will be also counted as a partial absence.

Exams:

The exams will be combination of short answer (including definitions), multiple choice, and essay. Exams are cumulative, but emphasize material covered since previous exam. While primary emphasis may be given to material covered in lectures, test questions also draw on material covered in greater depth by the text and other assigned readings. Three of the four exams will be used in computing the final grade. Therefore, there will be no make-up exams nor will exams be administered at any time other than the regularly scheduled class period. (This applies to the final examination as well.) The final exam will be comprehensive. The final exam can be waived if a student achieves 92% or better on all four hour-exams.

Written Assignments:

The written assignments are designed to provide you with experience in interpreting nutrition research, relating different researchers' work, and writing your interpretations.

Abstracts (40 points each, due dates see calendar.)

Select two original research articles, other than the articles on reserve, published within the last five years, and dealing with a micronutrient topic. (In a research article the authors have collected and analyzed data themselves as opposed to reviewing other people's work or reporting opinions). The first abstract should be about a vitamin. The second one is about a mineral. Summarize the research article chosen using the following format. (250 words maximum and double space)

1. Start with the citation--Author(s), last names first, initials. Title of article. Journal name, year;volume No.:pages. . EXAMPLE: (Journal of the American Dietetic Association style)

1. Munoz JM, Sandstead HH, Jacob RA, Logan GM, Reck SJ, Klevay LM, Dintzis FR, Inglett GE, Shuey WC. Effects of some cereal brans and textured vegetable protein on plasma lipids. Am J Clin Nutr. 1979;32:580-592.

Note: Include every author and use the correct spacing and punctuation.

2. Purpose--why was the study done? This is generally made clear by the author(s) in their introduction. Again, use nutrition research articles (if the purpose is to discuss someone else's work then it is not a research article.)

3. The methods or procedures or measurements used--whom or what was studied (adults, men, rats, gerbils, etc.) and what was measured (weight/height, bone breaking strength, enzyme activity, etc.)?

4. Results--what was found. (e.g. when alcohol intake increased, cerebral ethanol increased correspondingly and cell destruction also increased.)

5. Conclusions--how did the author(s) interpret the results or what does the study mean?

6. Your evaluation--what is your opinion of the study? This is the only section that should include your own opinion. Was the study worthwhile? Do you think the author(s) might have done something more? Do you have any questions about what they did, why they did it, and/or how they interpreted the results etc.?

7. Include a copy of the original paper when you hand in your abstract. Make sure the pages are stapled together. If it is a printout from the Internet, make sure the article is completed with all tables, figures and references.

Please Note: Copies of Published Abstracts, Direct Copying of Sentences from the Text of the Article, or Other Forms of Plagiarism Will Receive No Points but Will Be Counted as Your Assignment. The completion of these two assignments should be independent from any work that you received from other courses.

NTDT401-080, Honors Section

Since the standards for Honors program are higher than the regular section, Honors students will be required to complete every requirement of a regular section student except the abstracts will be replace by a term paper. The option of dropping the lowest hour exam score is not available to honors, although your exams will be graded according to the same standards as those for the regular section students.

Term Paper (For Honors only 100 points)

The first step for this assignment is to choose a topic. The topic needs to be related to the course and needs to be narrow enough to fit into 10 to 12 pages but broad enough to have at least 10 good references. For example, "Calcium" is much too broad and "Calcium and bone density" is much to narrow. The best way to choose a topic is to browse through the journals you are using to find your abstracts and, of course, to think about an area of special interest to you. The assignment schedule is as follows and you are requested to propose the actual due days for each at the beginning of the second week of the semester.

1. Topic name, outline, references. Prepare a brief outline of the topic, as it will be developed for the paper and cite 5-10 references to show that sufficient information exists to do justice to your paper.

2. Ten annotated bibliographies of your references. These are similar to abstracts but they are much shorter. use the same citation format then in two or three sentences describe the major point of the article. These should form the basis of your paper.

3. The final paper. The Term Paper will be graded on:

Technique - grammar, punctuation, spelling

Concepts - your understanding of the topic

Style - flow of thought, level of discussion

Grading: (For Honors only. Note: all four exams will be counted)
