SCI 220 Human Nutrition Vitamin Case Study

SCI/220 Human Nutrition

Vitamin Case Study:

Consider the following scenario:

In the winter, Max is plagued with one cold after another. He generally does not take vitamin supplements but decided to explore the possibility of taking a vitamin C supplement to decrease the number of his winter colds.

Max began by completing a literature search, which revealed approximately 60 recent articles.

He selected the following two:

Study One: A double-blind study in which a control group of 50 individuals receiving a placebo was compared to an experimental group receiving a supplement of 1,000 mg of vitamin C per day for 4 months. Participants did not change their diet during the study. Each study participant recorded the appearance and disappearance of cold symptoms for the duration of the study. The results indicated no difference between the two groups regarding the number of colds they experienced.

Study Two: A double-blind study occurred in which 20 study participants were housed for 2 weeks in the metabolic ward of a nutrition research center. Ten received a placebo, and 10 received a supplement containing 1,000 mg of vitamin C. All subjects consumed the same amount of dietary vitamin C and spent 4 hours in the same room with an individual with a cold. The appearance, severity, and disappearance of cold symptoms were monitored by a physician. Results indicated that there was no difference between the vitamin-C group and the control group in terms of disappearance of cold symptoms; however, the vitamin-C group had milder colds that disappeared more rapidly.
