Cholesterol and Blood Pressure Project

Evaluate and summarize 2 primary scientific papers regarding cholesterol or blood pressure.
The purpose of this part of the project is for you to utilize peer reviewed scientific journals to evaluate primary/original research papers. AND to be able to interpret the scientific results into terms that your future patients would understand (i.e., what is the take home message?)

For this part of the project, you will need to utilize the library database of scientific journal articles to:
a.    search for 2 primary research papers regarding one of the topics listed below,
b.    obtain a copy of the FULL paper (NOT just the abstract),
c.    read it, and
d.    summarize the research papers in a way that would make sense to the general public

You must use 2 different primary research papers (not review articles) as references.  Summarize your findings in 250-500 words (excluding references).  Cite all of your references using appropriate citation style such as APA, MLA, or AMA within the summary and your references at the end (see book references for examples).

IMPORTANT: Please use original words and be careful not to plagiarize. You must include your summary in this document AND post it on the ‘Cholesterol/BP project’ forum on the discussion board for full credit. If you have questions about what peer reviewed primary research papers are, please ask.  The purpose is for you to find two different papers that did an experiment on the same topic.  And give me your conclusions based on these two papers.  What is your take home message?

Topics to choose from:
•    Relationship between body fat percentage and lipid concentrations
•    Relationship between plant stanols and cholesterol concentrations
•    Effect of fish oils on heart disease
•    Effect of high simple sugar intake and lipid profiles
•    Relationship between weight loss and blood pressure

NUTR 3010: Cholesterol and Blood Pressure Project
Name:                                                                                   Student ID#:

Complete this project using the results from your lab testing appointment at the Nutrition Clinic Laboratory.  SCAN and attach your blood lipid profile and blood pressure lab results to your completed assignment. Assignments without lab results will be automatically marked down by 50%.

The following screening tests are required to complete this assignment:
1)    Blood Lipid Profile
2)    Blood Pressure

This assignment covers chapter 19 as well as nutrition basics from chapters 2, 3, & 4 in the book. The summary in Part 3 covers the module on “Using the Scientific literature”.
Record your results in the spaces provided and answer the questions below.  You will be evaluated on proper grammar, completeness, thoroughness, and accuracy. The goal of this project is for you to accurately determine and professionally interpret the results as if you were doing so for a patient. FOR ALL QUESTIONS: Explain your answer as if you were explaining this to a patient who did not know anything about these types of assessments. This assignment will likely take you more time to complete than the previous two assignments.  Allow adequate time to complete.

PART 1
1)    Report the results from your blood lipid profile (for those that were measured) and the recommendations for all values.
Your Results    Optimal or Desirable Range
Total Cholesterol (TC)
HDL
TC/HDL ratio
LDL    Not measured
TG    Not measured

2)    List 4 dietary factors that affect blood lipid concentrations and explain how each factor affects one of the cholesterol fractions.  (e.g.. high intakes of saturated fat increase TG levels) Do not list specific foods.

3)    If your TC concentration is too high, what dietary changes should you make to lower it? (List at least three different things. Do not include lifestyle changes (e.g. exercise)
If your TC level is within the recommended range, what dietary factors do you think contribute to your normal cholesterol?

4)    List two non-dietary factors (i.e. lifestyle factors) that can be altered to influence blood lipid concentrations.

5)    If TC concentration is >240 mg/dl the American Heart Association suggests implementing a Therapeutic Lifestyle Change (TLC) diet.  Outline the parameters of the TLC diet and calculate the amount of each nutrient that you should consume based on your IBW and Total Energy Requirements (from assignment 1).

TLC Diet     List recommended parameters        According to your Total Energy Requirements from the first assignment, translate the TLC recommendation parameters to meet your daily needs
Ideal Body Weight    j.
(% total energy)        Total Energy Requirements (kcal/d)    k.
Total Fat    a.        Total Fat    l. Kcal/d =                        g/d =
Saturated     b.        Saturated     m. Kcal/d =                        g/d =
Polyunsaturated     c.        Polyunsaturated     n. Kcal/d =                        g/d =
Monounsaturated     d.        Monounsaturated     o. Kcal/d =          g/d =
Carbohydrate    e.        Carbohydrate    p. Kcal/d =                        g/d =
Protein: % kcal    f.        Protein    q. Kcal/d =                        g/d =
Total Cholesterol     g.        Total Cholesterol     r.
Dietary fiber    h.        Dietary fiber    s.
Soluble fiber    i.        Soluble fiber    t.

Ex. If the TLC recommendations for total fat is 25-35% total energy intake (box a), and my total energy requirements (kcal/d) is 2200 (box l), then:
Step 1 convert percentages to calories: 2200 kcal x 25-35% = 550-770 kcal/d
Step 2 convert calories to grams: 550 kcal/9 kcal/g = 61 g/d and 770 kcal/9 kcal/g = 85.5 g/d
Note: Remember CHO and PRO have 4Kcal/gram and FAT has 9Kcal/gram
Therefore, box m would state the following: kcal/d = 550-770    g/d = 61-85.5 g/d

6)    Create a sample 1 full day menu that would fit the TLC guidelines. Your sample meal should meet your kcal requirements(± 100 Kcal), total fat (± 10g), saturated fat (± 5g), protein (±15g), carbohydrates(± 20g), fiber(within the range), and cholesterol recommendations (within the range) AND fit the food recommendations of the TLC guidelines.  Be sure to list daily total for kcal, total fat, saturated fat, protein, carbohydrates, fiber and cholesterol. Use the diet analysis software that came with your book, or the diet analysis program at http://ndb.nal.usda.gov. (3 pts)

(g)    CHO

PART 2
Now consider your blood pressure.
1)    Report your systolic and diastolic pressures below:
Systolic pressure:                                           Diastolic pressure:

2)    Hypertension, or elevated blood pressure, is defined as:
Systolic pressure:                                           Diastolic pressure:

3)    Explain the relationship between blood pressure and atherosclerosis. (What does high blood pressure do to the vessel to lead to atherosclerosis?)

4)    List/describe four dietary/lifestyle factors that can be altered to lower blood pressure.
