Internet Assignment 2 |
| Instructions:
Read the follow material and use the internet to obtain information. Answear the questions on a seperate text document such as MS Word, Notepad or Write then send it to me as an e-mail attachment at barry_bw@yahoo.com Assignment Two
Fortunately there are people out there in cyberspace, many times experts in their fields, who cruise the Internet, find the best, most useful, Websites, and put them all together in a subject directory for other people to use. |
| One example of this is The Food and Nutrition Information Center , a health information organisation dedicated to providing credible information, community, and services. They pride themselves in providing health news for the public, medical news for physicians, up-to-date medical reference content databases, and much more. |  |
|||||||||
| Let's look for mediterranean diet. Type your search words in the "Simplek Search" box on the FNIC Databases The data base is found on the write of the page |
|
|||||||||
| Your results will look something like this.
Click on a few of these and see what they have to say. Most of them are news articles, quoting reliable-sounding studies coming from highly respected medical journals. The authors are often health and medical journalists.
|
Unfortunately, details about research or trials is not given. One way
to check on the reliability of the article is to search again in Medline,
using any names mentioned in the article, or place of the study, or any
other key terms.
|
| As an example, I found an article that claims that a Mediterranean diet may help control diabetes. I can search Medline at ( http://www.medlineplus.gov/ ) for the phrase 'mediterranean diet', plus the term diabetes. | |
| The Medline search engine wants phrases entered with surrounding
quotation marks. Be sure to use the double quotes: "mediterranean diet".
Besides the phrase, I want to look for the word "diabetes". This is what
my search strategy will look like:
"mediterranean diet" diabetes I don't have to worry about capitalization, or the Boolean AND.
|
|
| And here is one of the first items on my result list. By
clicking on one of the author names, I can see a detailed summary of the
article.

Question Two:
Write a citation for any article in Medline that supports (or contradicts) the article you found in FNIC. Remember how we write citations:
And for multiple authors, we list all their last names and first initials. Each are divided by a comma, except for the last one, which comes after an ampersand:
Cicconetti P., Tafaro L., Tedeschi G., Tombolillo M.T., & Marigliano V.
Question Three:
Explain how this article supports the FNIC article. (Or how it contradicts the My WebMD article.)
| Let's look at another subject-specific site, the Nutrition Analysis Tool from the University of Illinois.( http://www.nat.uiuc.edu/mainnat.html ) Select Nats Var 2 from the right hand list. This brings up a site that lets you enter personal information about your age, gender, and the individual items of food that you've had to eat (for today or yesterday or last week), and then will analyze these foods for their nutrient content: calories, protein, fat, carbohydrates, fiber, calcium, iron, sodium, and many more nutrients. | ||
 |
||
| For each food that you enter, you'll be given a list of choices from the NAT database, with your food listed in several varieties (cooked, raw, juice, babyfood). Pick the one closest to what you ate, then pick the amount closest to what you ate. You'll end up with a list like this (with different food, of course): | ||
 |
||
| When you've entered in the food you ate for one complete day, click on Analyze Foods. From the Analysis Results Screen, answer these questions: | ||
Qusetion Four:
|
||
| You can save this table to a disk and add to it to keep track of your meals over the next week. Follow the directions on how to save. |
| Another online
resource for health information is the
Nutrition
Information & Resource Center website from Pen State
University.( http://www.psu.edu/) This site is a rating and review guide that attempts to solve the
two major problems Web users have when seeking nutrition information: how
to quickly find information best suited to their needs and whether to trust
the information they find there.
Pen sate
Nutrition Information & Resource Center tries to help you sort through the large volume of nutrition information
on the Internet and find accurate, useful nutrition information you can
trust.
Websites are reviewed by Pen State nutritionists, who apply rating and evaluation criteria based on currency and accuracy (10 points), depth of information (7 points), ease of use (5 points) and how often the site is updated (3 points), for 25 total possible points.

| If you click on the General Nutrition Information in the menu
on the left, you'll next see
a list of three databases dealing with nutrition websites . Do a key word
search for something you find interesting. Scroll down through the list until you find
a suitable reference. Click on it, and browse through their site.

Summary |
We have looked at three Internet sources of health-related
information:
We have also revisited Medline, which is probably the most reliable source of medical information available. You've also been introduced to the way Medline searches for phrases:
