This article provides astonishing findings about a study done by cancer biologist Susan Erdman, Eric Alm, and team. The study was experimental, and it looks at the effects of prebiotic yogurt on obesity. The experiment done on a male mouse showed increased fertility and masculine behaviors. They biologists were following results of a long term study done by the Harvard school of public health. The study was, therefore, biased as they did not know whether the previous study was credible enough. According to the results obtained by the Harvard school of health, more than any other food, yogurt helps preclude age related weight gain (Dolgin, 2012). They decided to do their experiment on mice. They took 40 males and females and gave them junk food and supplemented half of all diet groups with vanilla yogurt. Taking 40 subjects from both sexes was a good thing. This is because the results expected could have been due to other nutrients. In addition, a large number of subjects helps to evidently ascertain whether the results are attributable to the associated cause. The core objective of this study was to check the effects of prebiotic diet on overweight and related complications such as cancer (Dolgin, 2012).
In the previous study, done by the Harvard school of health, prebiotic yogurt help reduce weight related to age. With this in their minds, you would expect this study by the Erdman and team to be biased since they know the results. However, to our surprise these researchers were able to notice other entertaining aspects that we did not anticipate. According to their results, yogurt eating mice were extraordinarily shiny (Dolgin, 2012). They did not expect these results as their only objective was to explore the effects of prebiotic yogurt on age related weight gain. Another positive thing about these researchers is that they continued finding out whether there are more changes. Using both cosmetic rating scales histology techniques, the researchers found out that the mice had active follicle density that was ten times of other mice, consequential to luxuriantly silky fur (Dolgin, 2012). This was not the end of this experiment; the researchers also spotted something unique in all male mice. All yogurt eating male mice projected their tests outward, which according to the researchers, endowed the mice with a “mouse swagger”. They then decided to measure the male’s testicles. They found out that yogurt eating mice testes were heavier when compared to those mice fed with typical diet alone. They were also heavier than those of other junk eating males but not supplemented with yogurt (Dolgin, 2012). This change in testes size also helped the mice during mating, and found out that the masculinity paid off. In mating, yogurt eating mice inseminated faster and produced more offspring when compared to control mice. For the yogurt eating female mice, they gave birth to larger offspring and dissuaded them with great success (Dolgin, 2012).
After the experiment, Alm and Erdman concluded that prebiotic microbes found in the yogurt van help animal become healthier and leaner and improve their sexual machismo. In my own opinion, these results are good and based on evidence. The researchers were able to do more than three experiments I order to ascertain that probiotics milk improves masculinity (Dolgin, 2012). These results could also have implications for human fertility. In order to find more on this issue, Jorge Chavallo (Harvard nutritional epidemiologist) did an experiment to check out the association between semen quality and yogurt intake in men. The findings were consistent with the previous study that we have seen in the mice (Dolgin, 2012).
In my opinion, I think that this study was done well, and the researchers were not biased. The researchers did not limit themselves in only finding the effects of prebiotic yogurt on age related weight gain. Another positive thing about this experiment study is that it came up with more results not anticipated. For instance, we did not expect the researchers to do any more experiment other than effects of yogurt on weight gain. However, there is one thing that is contradicting in this study. The core objective of the experiment study was to find out the effect of prebiotic yogurt on age related weight gain. When the researchers found out other results that they did not project, they forgot there objective. When you read the results of the study, there is nowhere the researchers have talked about these effects of prebiotic yogurt on age related weight gain. On the contrary, the researchers only concentrated on the new results. They concentrated on effects of yogurt on mice such as incredible shiny, testes projected outward and faster insemination. In the discussion of the results, the researchers still do not mention the effects of prebiotic yogurt on age related weight gain that can cause cancer. Instead, they only concluded that prebiotic microorganism found in yogurt help animals healthier and leaner (Dolgin, 2012).
