Subsistence Strategies From Four Discrete Categories ...

I would like to address topic A, regarding the placement of subsistence strategies into four discrete categories: hunting and gathering (foraging), horticulture, pastoralism, and agriculture. While this quick categorization of human subsistence behavior has benefits to introduce these concepts, it falsely assumes that each behavior exists independently and ignores their location on a continuum, often blending from one strategy into the next. In this essay I will introduce each subsistence strategy, show examples of it and finally show ways that even among groups of people who would seem to fit the archetype of each behavior they often adopt strategies of others in a sort of mixing and matching process, especially in times of duress. First, I would like to discuss the strategy of hunting and gathering, the sole strategy until twelve thousand years ago. Hunting and gathering is a form of subsistence dependent upon wild plants and animals for the majority of the calories of the diet. Wh ile its name underscores the importance of hunting in this lifestyle, this is misleading as the majority of caloric needs in societies practicing this strategy are met by gathering wild edible plants and berries. Due to the dependence upon naturally occurring sources of food, which are not always found in the same abundance as in agricultural cultivation, hunter-gatherers are usually found in bands of less than fifty people and in areas with low population density.

Sandra Cisneros and Hughes Analysis - 1575 Words

Discrimination has and always will be controversial, whether it is because of sex or color of skin it will always be around. Writer inspiration seems to come from firsthand accounts and experiences, at least that is the case with Sandra Cisneros, a Chicana writer, and Langston Hughes, and African American poet. When reading their stories the reader can identify how different life experiences have influenced and inspired them to write the way they do. Analyzing Sandra Cisneros and Langston Hughes, and pieces of their writing will demonstrate how similar their writing is, how minority discrimination, and cultural circumstances effect and shape different pieces of their respective writings. This paper will highlight similarities, differences†¦show more content†¦Whereas for Hughes, he strived to connect and unite enslaved, black people. The similarities in both authors are the cultural obstacles they had to surpass to be the successful writers they became. A deeper examination of Cisneros’ famous short story, â€Å"Woman Hollering Creek† will highlight the liberation of those barriers. In this particular short story Cisneros speaks about the main character, Cleofilas, and her struggle with her abusive husband, Juan Pedro. Cleofilas had to live in a society where the women were simply there to assist their husbands, and God forbid she second guessed him. Living and struggling with the everyday battle of stereotypes, she decided to leave her husband at the end of this short story. This all developed the strong independent female role Cleofilas took on by the end of the story. The main character was forced to believe by her family and her husband that she wasn’t worth anything without a man; this made her doubtful of her abilities and her human capital. In the interview by Martha Satz, Cisneros says, â€Å"I think many of my stories come from dealing with straddling two cultures, and certainly its something Im going to deal with in futu re stories† (Cisneros 30). Here, Cisneros agrees that her stories have to do with the endless topic about coming from two cultures and the stereotypes it brings along. From firsthand accounts the Mexican American culture is embraced by â€Å"machismo†, or that male superiority. â€Å"Woman Hollering Creek†

Omega 3 Fats in the Diet for Child Health- myassignmenthelp.com

Question: Discuss about theOmega 3 Fats in the Diet for Child Health and Nutrition. Answer: Omega 3 - Facts and Benefits to live a Healthy Life Fats are one of the most important components of any healthy diet that maintain various body functions of a living organism. Health benefits of Omega-3 and Omega-6 are endless, that enable it to be incorporated in every prescribed diet chart. In order to discuss the omega-3, the fatty acid is another essential concern. Since 19th century Fish oil has been used in England and other European countries for its variety of health benefits. A healthy amount of fish oil consumption has been proven highly beneficial in Greenland. It has been identified that high amount of fish oil consumption has significantly reduced the frequency of heart disease among citizens. Henceforth, numerous natural resources that can be incorporated into daily diet chart in order to maintain the healthy amount of omega-3 consumption instead of using medicated supplements. Classifications of Omega-3 Omega 3 fatty acids are extremely important for health, while it cannot be produced within the human body. Therefore, the classification of Omega- 3 has to be identified. Two of the most commonly founded components are Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA). These acids are not easily found in the fish sources like sardines and salmon (Calder 2015). In addition, the last one is Alpha-linolenic acid or ALA, which can be found in the plant sources like seeds and nuts. In spite of available sources, supplementations are often used in daily life for fulfilling the Diet gap. However, the best way is to consume Omega-3 rich food rather than the supplements. It has been researched that Human body is capable of converting ALA into EPS and DHA. It is true that EPA and DHA is most preferable but those who cannot consumer fish they can add seeds and nuts in their meal for fulfilling their diet gap (Kang, Grodstein, and Manson 2015). In this context, people might have a quest ion that Do Omega-3 Food items make any difference? Nutritional study on Omega-3 sources Identify the natural resources of omega-3 fatty acid is crucial to make a healthy diet plan. Mackerel, Shad, Salmon, whitefish and Bass are the massive source of Omega-3. In these sources, the amount of fatty acid ranges from 1567 mg to 3367mg. Vegetarians also have the opportunity to fulfil their needs through consuming ALA-rich vegetables. These vegetables are Chia Seeds, Flaxseed, broccoli, Hemp Seeds, Grape leaves and Spinach. In this case, the fatty acid amount is ranged from 961 mg to 8543 mg (Koh 2017). Therefore, there is the maximum amount of sources, which could be added to the daily diet to maintain healthy well-being. Previously it was believed that the nutrition rich diet of omega 3 could be the cause of healthier and longer life. Plant sources could be adequate, but maximum fatty acid amount and antioxidants could be lost during the purifying process. These factors are still in the debate, but now the topic is to deal with nutrient-dense diet, where Omega 3 is required. In order to address this question, the issues and consequences regarding the deficiency of Omega-3 fatty acid have to be clarified. Importance of Omega-3 The term malnourished is primarily considered to be a cause while, people are unwell, pale and underweight. However, this conception is not necessary for all cases. The absence of vital nutrients from the regular diet can lead to severe health consequences. For the Australian malnourish and overweight is not a new factor. In this context, Omega-3 acids play the crucial role in the brain development (Meyer 2016). Omega-3 also maintains the cardiovascular health by lowering blood pressure, cholesterol, and plaque in the arteries. Omega-3 has a significant anti-inflammatory impact, which could lower the risk of possible chronic diseases regarding bones and tissues health. For men required amount is 160 mg, and for adult women, this amount is 90 mg. Omega-3 also prevents diabetes Stabilizing blood sugar levels and insulin. During lactating and pregnancy state Omega-3 is a very important component. According to various studies in Australia, Omega-3 has been identified for improving variou s mental conditions, such as depression, anxiety and others (Grant et al. 2013). Omega-3 is also used to treat various digestive disorders like ulcerative colitis. As reported by the National Heart Foundation recommends the consumption of Omega-3 food at least twice a week to avoid such health issues in future (Srednicka-Toberet al. 2016). According to various cancer research and studies conducted globally, Omega-3 has been also found to reduce the risk of cancer. Moreover, omega-3 is a widely used component for improving the skin conditions and appearance. Omega-3 supplements and the diet gap Omega-3 is present less amount in the plant foods.It is important for the vegetarians to understand the requirement of Omega-3 rich diet in their body. It is true that the plant food source contains little amount of ALA, a shorter chain of Omega-3 (Nguyen et al. 2014).They can take hemp seeds, flaxseed, chia and walnuts. These sources are equally beneficial as the direct sources, but there is much variation among people to maintain their dietary needs. Therefore, they can take supplements to fulfil their requirements as per the advice of a dietician, doctor or other health professional. There is no proper side effect of these supplements, but medical advisers have to prescribe those as per the required level (Patrick and Ames 2015). Otherwise, the excessive consumption of the same can lead to severe health consequences. Omega 3 and Omega 6fatty acids are essential and integral part of the diets but it should be consumed in balance. Excessive intake of supplement could be the cause of imbalanced nutrient status or other side effects. Therefore, consuming essential components like omega-3 fatty acids can be consumed through various natural resources instead of using the medicated supplements. Health implications Omega-3 fatty acids are related to the optimal function of the neuron, and it improves nerve transmission. In many cases, research studies have suggested that this acid can boost the level of dopamine and serotonin (Saberet al. 2017). These hormones are required to decrease the depression level. In the various clinical trials, people have been treated with Omega-3 fatty acids, and a positive result is displayed for reducing the risk of depression. It also benefits the skin. Psoriasis is the type of skin disease that causes acute inflammation, scales and redness. In this case, Omega-3 can suppress this issue of skin inflammation. New research studies explain why it is important to recognise the impact of Omega-3 in cancer cells. There is also epidemiological evidence, which displays that men are at lower risk of Prostate cancer through consuming more fish. Omega-3 supplementation is useful for resolving the issues of other inflammatory diseases like ulcerative colitis, rheumatoid arth ritis as well as Crohns disease. From this discussion, it can be said that Omega-3 deficiency is a major issue that could create serious concerns about the health like depression and other disorders. In Australia, a huge number of patients are experiencing such problems due to excessive use of Omega-3 supplements instead of incorporating omega-3 consisting foods in their regular diet plan. They can fulfil their dietary gap with the help of the plant and supplement sources. However, the proper advice is required to resolve the issues of imbalance of Omega-3 because it creates inflammation issues. Therefore, natural diet is safe rather than the supplementary products. Natural resources of omega-3 can be included in regular diet chart to reduce the risk of obesity, cardiovascular disease and diabetes. Everyone who wants to have a healthy life has to consume the omega-3 fatty acids and other omega groups maintaining the accurate ratios as per the guidance of an expert.

Turners Syndrome Essays (227 words) - Syndromes, Cytogenetics

Turner's Syndrome Turner's Syndrome Turner's Syndrome is a common disease in females that affects many body systems. It affects about out of 2,000 females. This genetic disorder is characterized by the lack of sexual development at puberty. Although the exact cause of Turner's Syndrome isn't know, it is believed that the disorder may result from an error during the division of a parent's sex cells known as meiosis. Turner's Syndrome is a defiency in the amount of genetic material on the X-chromosome, one of the two-sex chromosomes. In some cases of Turner's Syndrome, one X chromosome is missing from the cells. In other affected females, both X chromosomes may be present, but one may have genetic defects. One other case of Turner's Syndrome, some cells may have the normal pair of X chromosomes while other cells do not. An examination of genetic material, usually by a blood sample, can confirm the diagnosis. This condition may first be recognized in the newborn baby, in the adolescent or rarely in the adult. Some signs and symptoms include infertility, a low hairline, webbed neck, and usually kidney and heart malformations. There are other problems associated with Turner's Syndrome such as learning difficulties, skeletal abnormalities, heart and kidney abnormalities, infertility, and thyroid dysfunction. There is a treatment for Turner's Syndrome. Recent studies show that much of the growth defiency in people with Turner's Syndrome can be restored by injections of human growth hormone. Medicine Essays
