Effect of Green and Black Teas Essay Example for Free

Effect of Green and Black Teas Essay Determining the efficiency of various types of teas and its components, and the binding of tea with lipoproteins as for prevention of the occurrence of coronary heart diseases, is the primary objective of the study. Based on established scientific researches, one of the components of tea called phenols, are responsible for producing the antioxidant attributes of tea. Further studies prove that both black and green teas have almost the same phenol content. Thus, their antioxidant strength is also the same, as gauged through the use of the phenol antioxidant index (PAOXI). Moreover, the study establishes the idea that a combination of tea catechins and lipoproteins produce stronger antioxidant qualities. (Vinson Dabbagh, 1998a) To accomplish the objective of the study, teas that were used for samples were prepared using the same process. These samples were then compared to other types of antioxidants and other beverages with phenolic content. Moreover, the teas were studied in order to find out the threshold for the production of antioxidant properties, and also the binding of antioxidants with lipoproteins. Vinson Dabbagh, 1998a) The results of the study revealed that green tea produces higher antioxidant activity than the black tea, the green tea and black tea were stronger antioxidants than other beverage samples, the PAOXI of both green and black teas do not exhibit significant differences in terms of antioxidant strength, and the lipoprotein binding for both teas remain the same. Moreover, the catechins found in teas were more effective than vit amins C, E and beta-carotene in binding with lipoproteins to complete oxidation. Therefore, teas are more efficient in lowering the risks of coronary heart diseases. Green teas were found to bind efficiently with lipoproteins of high amounts, and on the contrary, black teas were said to bind efficiently with lipoproteins of low amounts. (Vinson Dabbagh, 1998a) Secondary Source The discovery of the connection between oxidation and atherogenesis has incited research studies about the effects of antioxidants found in teas to lipoproteins. Moreover, studies conducted on flavonoids, which is one of the components of tea, and its contributory effects to the prevention of the occurrence of coronary heart disease, has led researchers to speculate that catechins that are found in tea might be instrumental in promoting health and wellness due to the antioxidant attributes produced by teas. (Vinson Dabbagh, 1998b) This particular research study aims to identify the efficiency of teas as a source of antioxidants as compared to other beverages with the same phenolic content, and the maximum threshold of the production of antioxidant mechanisms in teas. Moreover, research was conducted on the effects of binding antioxidant with lipoproteins to an individual with low antioxidant intake. (Vinson Dabbagh, 1998b) The results of the research reveal that catechins that are found in teas are more effective antioxidants as compared to other vitamins that claim to be a good source of antioxidants, such as vitamins E, C and beta-carotene. Moreover, the research also discovered that teas bore the most amount of phenolic content as compared with other beverages that were tested, and that among the tea samples that were tested, green tea bore the most amounts of phenolic content. In addition, antioxidant binding with lipoproteins was most efficient with black teas as compared to other teas, although there was not any significant difference as to the effect when comparing it to the results of other teas. (Vinson Dabbagh, 1998b) In conclusion, the research study reaffirmed the fact that teas are a great source of antioxidant and that they are effective in producing high levels of antioxidants that are needed by the human body. Therefore, an individual’s regular intake of tea prevents the onset of lipoprotein oxidation within the body. (Vinson Dabbagh, 1998b) Personal Opinion about the Topic The results of the study has proved the effectiveness of teas as a source of antioxidant, therefore supporting previous studies conducted about the relationship between catechins and phenolic acid that are found in teas and its binding with lipoproteins as instrumental in the lowering of risks caused by coronary heart diseases. If this is the case, then regular intake of green and black teas should be recommended to people who are at risk for coronary heart disease and should be recommended as part of the average person’s diet in order to avoid the occurrence of the said disease. Although plants where tea comes from are widely grown all over the world, and according to the study, tea is the most popular drink in the world, people still do not realize the importance of its content and the regular intake of tea as a protective instrument against coronary heart disease. Moreover, people are not aware that the beverage that they enjoy the most has health benefits that might save them from suffering heart diseases. Promotion and recommendation of teas that are based on research study results and information dissemination might help in encouraging people to drink tea as part of their diet in order to stay fit and healthy. Aside from advertising and promotional activities, the government should support or fund the horticultural industry in order to produce more sources for green and black teas. Not only will the people benefit from this, but the government will also gain profit for the tea industry and agriculture. Moreover, the government should look into the processes of preparing teas. As the research study suggests, that the amount of phenols within the tea leaves, which are said to be the ones responsible for producing antioxidants, are dependent on the weather and climate, age of the tea leaves that will be used, and the horticultural processes that the leaves underwent. Therefore, the government should further look into the processes from which tea leaves are produced. Desirable and specialized horticultural processes should be employed in growing plants in order to ensure the quality of tea leaves that will be grown from it. In order to accomplish this aim, the government should be able to conduct research studies that would prove to be instrumental in the efficient and productive growth of plants. Moreover, with further studies and in depth research, the government should fund the inclusion of teas in the diet of patients in the public health care system, especially those who are suffering from coronary heart diseases, patients who are at risk, and even all the patients in order to keep strong and healthy. However, further studies should be done independently in order to avoid judgments of researches that are tainted by underlying motives such as advertising. In the research study conducted by Vinson Dabbagh, it was funded by the Lipton Tea Company. Since the Lipton Tea Company is a business organization, which produced tea all over the world, I cannot help but think of the politics between business and advertising that is concealed in the research. Most especially because the results of the research promoted the efficiency of green and black teas among other beverages and its importance as a prevention scheme against coronary heart diseases. In order to invalidate speculations that might arise from the influence of Lipton Tea Company and the research, independent studies should be conducted by professionals and scholars alike from different fields related to the issue such as representatives from the health care industry, agriculture, government, universities, and scientists alike.
