Chapter 9

A pregnant mother who has been eating more fish to obtain a good supply of n-3 fatty acids read a newspaper article indicating that all ocean fish are contaminated with mercury. She is concerned about the safety of her baby. Review the current advisory of the FDA (www.fda.gov and Box 9-4) regarding the consumption of fish by pregnant women. How would you advise her?
Find a print or Internet advertisement for a new dietary supplement or health remedy and identify the population to whom it is directed. Using the criteria in Box 9-5, evaluate this product. Does it appear to be helpful or harmful? How would you respond to a consumer seeking your advice on its use?

You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.

Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.

Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.

  • The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.
