Vitamin C Linked To Reduce Cataract

Jessica Sizemore

Summary of Article

A cataract clouds the lens of the eye, causing it to be opaque and reducing vision. Cataracts effect nearly 29.2% of older Americans and is the leading cause of blindness worldwide. Researchers have found that a person who's diet includes a large amount of Vitamin C has reduced their chance of getting cataracts by 20%. Researchers also discovered by this study that genetic factors were responsible for 35% of cataract regression and diet was responsible for 65% of cataract regression. Researchers believe that the reason large amounts of Vitamin C reduce cataract progression is because of the antioxidant properties found in Vitamin C. Researchers believe that the Vitamin C goes into the fluid inside the eye and gives the eye extra protection to prevent cataract progression. This study by these researchers only looked at Vitamin C intake through diet and not through dietary supplements. The most important finding was that Viitamin C intake from food seemed to protect the eye from cataract progression. While researchers are still unable to prevent cataracts from developing they have found a way to reduce cataract progression or delay their onset and keep cataracts from worsening by eating foods rich in Vitamin C.

Critique of Article

I want to start this critique by beginning with the author. After doing some research on Yvette Brazier I discovered that she does have a degree in journalism, but does not have a degree in anything medical or health science. However, since 2005, Ms. Brazier has worked at a technical college in the Health Science department teaching students and professors research, writing, and presentation skills. Since then, she has become qualified to be an Emergency First Responder. To me this is not enough of a background to make Ms. Brazier a credible source to write this article. I believe that Mr. Brazier may know some about health science and the medial field since she works alongside of people that do know a lot, but to me she is not an a credible author on this topic. I believe that an author with more of a medical or health science background would have made this article more credible.

Secondly, I want to critique this article because the research for the article was based off of studies in the United Kingdom (UK) and not in the United States. The reason I feel that this is not a good source of data is because Americans eat a completely different diet than they eat in the United Kingdom and we also live completely different lifestyles. For the data to have been more accurate studies should have been preformed on Americans. The American diet, for the most part, does not include may fruits or vegetables, which are key source of vitamins needed for our bodies. If they had done the studies on Americans they many have found that our bodies are so deprived of vitamins that may be increasing our intake of Vitamin C might not make a difference to the progression of cataracts. I obviously do not know what they would have found but I am just giving an example of what they could have found and then their theory would have been proven completely wrong.

I believe that the credibility of this article is not very high. The article is not supported by anyone other than the website that published it. The author has no background knowledge or education in the medical or health science field. The data that was used to support the theory was taken from participants in the United Kingdom and not in the United States, yet we still published the article for Americans to read. For this article to be more credible, there needs to be a lot more research done here in America and I believe that the results need to be supported by a multitude of medical doctors before I would consider it a credible theory.
