- a) Hypothesis
The article hypothesized that berries are important in fighting cancer.
- b) Experimental design
Based on the reading one of laboratory studies have been carried out to test the hypothesis. Also, various human studies have been performed to determine the significance of eating berries on people’s health. As the author writes, “some human studies have also suggested a benefit from berry consumption” (Parker-Pope).
- c) Results and Interpretations
One of the findings of a study carried out by researchers from Ohio State University was that black raspberries prevented esophageal, colon, and oral cancers from developing in rats. Another study on individuals with familial adenomatous polyposis found out that eating black raspberries reduced the chances of developing rectal tumors by 59 percent. Besides, article’s authors says that a study on two groups or rodents revealed that a powder of black raspberries that contained anthocyanin had the same level of effectiveness as the whole berries in relation to slowing down the development of cancer. Unlike the untreated rats, both categories of mice had 50 percent fewer chances of developing esophageal cancer. The researchers concluded that apart from the blueberries, most of the other fruits including raspberries, strawberries, blackberries, and elderberries contained cancer-prevention elements. The scientists also inferred that for human beings to ingest the same amount of berries as the rats used in the studies, they would have to consume approximately one pound of berries per day.
- d) Any theories developed that might be tested
One of the theories that could be tested was the effectiveness of the anthocyanin contained in the berries on cancer management. The researchers were also concerned about whether climatic changes and technological advancements may interfere with the amounts of the beneficial components found in the berries.
