Nutrition Information: Fact or Fiction?
Multiple Choice Questions
1. A researcher observes that first-grade children who only eat foods sweetened with honey
seem to behave the same as first-grade children who eat foods sweetened with cane sugar.
After making the observation, the research decides to conduct a study to explore whether
eating honey has any affect on school-age children's behavior. The researcher wants to follow
the basic steps of the scientific method. Now that he's made the observation, his next step will
be to
A. form at least two basic conclusions about behavioral problems that affect children who eat
sweeteners such as honey.
B. analyze information about the general dietary practices and common behavioral problems
of first-grade children.
C. ask a group of peer reviewers for their help in designing a single-blind study involving the
dietary practices of children.
D. develop a question that's based on his observations of the children's behavior and their
intakes of sweeteners such as honey.

2. A medical researcher asked 50 people with painful, arthritic knees to rub a cream that
contained vitamin E on their knees for two weeks. At the end of the two weeks, she asked the
subjects whether their knee pain improved, stayed about the same, or worsened during the
treatment period. All 50 subjects reported improvement in their knee pain. Based on this
information, which of the following statements is true?
A. The results of this study prove that rubbing a cream that contains vitamin E on arthritic
knees is a good way to relieve knee pain.
B. The researcher should find a peer-review group to analyze her findings about the vitamin
E-containing cream as a treatment for knee pain.
C. The results about the benefits of using a vitamin E cream for knee pain are questionable,
because the researcher didn't have a control group.
D. The researcher shouldn't report her findings, until she uses a single-blind study to test the
vitamin E-containing cream.

5. A scientist conducts a study to determine the effects of the mineral cadmium on the weight
of mice. She adds 5 mcg of the mineral to the daily diet of 100 4-week-old laboratory mice.
Every week, the researcher weighs and records the weight of each mouse. At the end of the
study, the scientist notes that 3 mice died, 40 mice lost weight, 40 mice gained weight, and the
remaining 17 mice didn't gain or lose weight during the 12-week period. Based on this
information, what would you tell the researcher about her findings?
A. The findings are very interesting and provide scientific proof that cadmium causes weight
loss.
B. The findings are not meaningful because of the way the scientist designed her study.
C. The findings are biased because the scientist used mice instead of humans in her study.
D. The findings are newsworthy and important enough to be published in a peer-reviewed
nutrition journal.
