Humans are the only organisms that prepare food by cooking. Does cooked food offer better nutrition than raw food?

Books
Use the Uni of Adelaide Library Catalogue to find books on this topic. If you find the books you want are on loan, you can make a request to recall the book, but even better would be to tell your lecturer who will then contact me to have the book placed in the Reserve Collection.

Journal Articles
I'm assuming that you have read the Library tutorial for science, and have a basic understanding of how to use electronic databases to find journal articles (covered in section 5 of the tutorial). If you haven't looked at this tutorial start your search for information by working through this now.

Before you use a database you should think about what you will search.
What are the main concepts in this question?
Write them down.

raw

cooked

nutrition

humans

Under each of these concepts write down any synonyms or alternative terms for each concept

raw	cook*	nutri*	human*
uncooked	steam*	bioavailab*
	boil*	availab*
	bake*	digestib*
	grill*	uptake
	fry*	absorb*

Are there other terms you could add to this grid?
how about fried, or baking

This should sort out most of the language requirements of your search.
Now you need to make sure that your search logic is correct.
The logic will sometimes be determined by the database you choose to search.

CAB Abstracts is a useful database to start with.

Logic
Join the terms that are in the same column of your logic grid with OR logic.
This means that your search will find for example, citations that include
raw or uncooked

Truncation
You can save yourself a bit of typing by using the truncation symbol *
Instead of searching for nutrition or nutrient or nutrients or nutritive etc you can use
nutri*
to get the same result.

Searching for Phrases
Searching for phrases will make your searches more specific.
Phrases need to be enclosed in double quotes
e.g. searching for "biological availability" finds the phrase, while searching biological availability will find citations that have both biological and availability included but not necessarily as a phrase.

You can get access to Biosis Previews by clicking on the Databases tab on the Library Home.

Next click on the Ecology and Evolutionary Biology link.

Scroll down the list of databases in alphabetical order to find CAB Abstracts .
Click on the link.

Enter your search terms from the first column of your grid into the top search for box.
Join the terms with or logic

raw or uncooked

Usually you'd search by Topic, and this will work for this search too, but there will be a lot of citations that aren't relevant turn up. To make this search more focused change Topic in the 'in' box to Title.

Type the terms from the second column of your grid into the second Search for box.
Change Author in the in box to Title.
When your results turn up raw or uncooked and one of the terms from the second column of your grid will be in the title.
This will focus your search.

Continue with the terms from the third column, remembering to change Publication Name to Topic in the in box.

To get a 4th Search for box click on Add Another Field >>

Add the terms from the 4th column of your grid,
Click on the Search button.

Click on Check full text options to see if the Library has particular articles.

Click on the title of an article to see more details.

Click on Related Records to find citations that may be similar.

Click on References to view the citations referenced by the article.

Click on the number after Cited by to view any articles known to cite the article you found.

Citations have hyperlinked numbers to the right.
Click on the number to see articles that refer to these citations.

If you need more help contact Mick Draper, but be warned that I will ask you if you have read the Library tutorial for Science, and what you have done to search for articles.
