It Is in the Misuse of Words

The two most common research techniques are to randomly select a nationally representative sample and conduct either a phone or written survey of the subjects. A few researchers select individuals for their survey, but another common technique is to select a random sample of Physicians and interview them about their patients.

The researchers used purposive sample but did not give any explanation as to why this choice sampling was made. It is essential to describe the sampling process in a research where this facilitates the reader to distinguish any bias in the whole sampling process. In studies using participants, the process of how to select, access, inform and retain research participants requires considerable thought. Sampling is a key issue, because it is

3. Vitamin E: A group of compounds; resistant to heat and visible light; unstable in presence of oxygen and ultraviolet light; stored in muscles and adipose tissue. Functions: an antioxidant; prevents oxidation of Vitamin A and polyunsaturated fatty acids; may help maintain stability of cell membranes. Sources: Oils from cerel seeds, sald oils, margarine, shortenings, fruits, nuts, and vegetables. Excesses: Nausea, headache, fatigue, easy bruising and bleeding. Deficiencies: rare, uncertain effects.

In multiple places in within the article the authors use definitive language, but they provide no statistic to back it up. You have to be careful when you are using definitive language, because, in society, there are bound to be outliers; people who do not fit into definitive statements.

To understand why the public’s health is in a precipitous decline it’s best to first look into the case of nutritional deficiency; are we getting all the vitamins and minerals our bodies require? One of the core issues is the misinformation on what a vitamin really is and why one should be concerned about this. The Food and Drug Administration has a firm stance that these synthetic vitamins

As you stated the authors mention that caution should be utilized when the results are interpreted. The research methods of questionnaires and self-reporting,

Beta –carotene toxicity cases are rampant among smokers. Physicians advise active smokers to avoid these supplements as their intake results in increase risk of lung cancer. Scientists have asserted that metabolites elements present in the Beta-carotene substances destroy retinoic acids that repress cancer growth in the lungs (Gutiérrez, & Gonzalez, 2010). In addition, metabolites catalyze proteins responsible for cell division hence activates the growth of cancerous cells. It is for this reason that smokers are prohibited from taking Beta-carotene substances. Thus, Beta-carotene supplements are best suited for diabetic patients and vitamin A deficient individuals.

The authors relied heavily on two studies to create their argument. The first study mentioned was the Pinto et al article. In this study, "Pinto and colleagues (5) assessed the

Your body is in a constant battle against infection, diseases and the formation of free radicals. However, there's a secret weapon that can help you fight against these things: antioxidants! Antioxidants are elements such as vitamins A, C and E that counteract the damage caused by free radicals and help protect your healthy cells. Free radicals are the molecules that contain unpaired electrons, which make them highly reactive. In this form, they can cause damage by attacking healthy cells, and when these cells grow weakened, you become more vulnerable to disease.

Cancer. We all know someone who has suffered from it or has passed away because of it. Cancer now affects one in every three people, and is the second highest cause of death in the United States. For decades, the medical community has been on the hunt for a cure for cancer, and have been subjected to intense ridicule from the public because of a lack of progression toward a possible cure. In recent years, many scientists, doctors, researchers, and the general public have come to believe that the cure for cancer is being suppressed because of this lack of progress. Those who say it is suppressed claim that the drugs used to treat cancer actually cause cancer, making a patient sicker and sicker. As a result, the patients are forced to spend

The participants of clearly the individuals from three separate cohorts, however the researchers do no specify if all individuals in each of the three cohorts are sampled or if only a portion of them participated in the research. This is an important issue that needs to be addressed by the researchers, although the number and sex of participants from each cohort is reported, the differences in sampling selections could present a significant difference in the conclusions obtained from the research data.

These studies only included undergraduate students, therefore consisting mainly of young adults. This raises questions on whether results can be generalised to those in all age groups.

We live in a society in which we are in a state of constant fear of diseases. From when we are young we are taught repeatedly to wash our hands before every meal and to eat an apple daily. Moreover, we are catechized on a regular basis to bundle up so we do not catch a cold or pneumonia. Likewise, our doctors advise us to visit them annually to make sure we don’t have deficiency related disorders such as scurvy or anemia. What if there is a vitamin that could aid in preventing the aforementioned illnesses? Would it not be worth a try? Consider this an introduction to vitamin C! Details on this “wonder vitamin” are elaborated in the subsequent paragraphs!
