Nutrition - Essay Example The Six Classes of Essential Nutrients Proteins, carbohydrates, water, lipids, minerals, and vitamins are the key essential nutrients for the human body. Proteins carbohydrates, water, and lipids are classified as macronutrients, while minerals and vitamins are classified as micronutrients (1). Insel et al, 2011, p.230, define proteins as â€Å"large molecules made up of amino-acids joined in various sequences†. Thus various kinds of proteins are present in the human body in various shapes. Based on their shapes the several kinds of proteins have specific roles within the human body. Some of them are enzymes, and speed up the many chemical reactions within the body essential to its survival. Some others act as hormones. Hormones may be viewed as chemical messengers within the human body. Yet other hormones go into the makeup of the antibodies of the human body to protect the human body from foreign substances and pathogens. Some other proteins act as pumps within the body to m aintain fluid balance. In this balance maintaining process they pump molecules across cell membranes and attract water. The acid base balance in the body is maintained by the action of proteins through the taking up or releasing of hydrogen ions, depending on the need. Finally, proteins act as transporters for many key substances like oxygen and the micronutrients to the targeted cells all over the human body. The essential nature of proteins to the human body is thus clear (2). Insel et al, 2011, p.146, define carbohydrates as â€Å"organic compounds that contain carbon (C), hydrogen (H), and oxygen (O) in the ratio of two hydrogen atoms and one oxygen atom for every carbon atom.† The main role of carbohydrates in the body is to act as a fuel for the cells in the human body. Even though the human body can use fats also for energy purposes, carbohydrates are the preferred source of energy, particularly for the brain, red blood cells, nervous system, fetus, and placenta. Carbo hydrates also contain fibres that make it easier for the passage of stools through the digestive system (2). Water is absolutely essential for the survival of the human body. The water content in the human body is responsible for up to 75% of the weight of the human body. The importance of water to the human body lies in it being a very good solute. In the human body water carries several dissolved minerals in the form of electrolytes. These electrolytes are maintained at a constant balance. The very existence of cells in the human body depends on the maintenance of the right balance of these electrolytes in water (2). Insel et al, 2011, p.182, describe lipids as â€Å"a broad range of organic molecules that dissolve easily in organic solvents like alcohol, ether, and acetone, but are much less soluble in water.† Three main types make up the lipids, which are triglycerides, phospholipids, and sterols. Lipids are an energy source for the body and when stored in the body as fat act as energy reserves in the body for use when there is a deprivation of carbohydrate supplies to the body (2). Ball 2004, p. 8, defines vitamins as â€Å"a group of organic compounds which are essential in very small amounts for the normal functioning of the body.† Vitamins as required for nutrition in the human body are thirteen in number and classifies into water soluble vitamins and fat soluble vitamins. The water soluble vit

Greeces Economic Crisis Research Paper Example | Topics and Well Written Essays - 1250 words

Greeces Economic Crisis - Research Paper Example 2-3). In a research paper of Cardiff Business School the researcher has concluded that the macroeconomic fundamentals like the inflation, the exchange rate arise for Greece which is more than the European average (Arghyrou and Tsoukalas, 2010, p.5). In a research paper of Capitalvia the researcher has opined that the economic situation of Greece and U.S.A. is similar as both of them are depending on the foreign investors for funding of the budget deficit. For the crisis the value of Euro would come down and the fact is that United States’ trade with EU is the highest. As a result the investor would lose confidence on U.S. economy and U.S. economy also would come down. According to this research though the U.S. investors’ investment is low in Greek bonds, if Greece would default the investors would lose money and U.S. economy gets hampered (Capitalvia, 2010, p.11-12). According to a research paper published by Konrad Adenauer Stiftung for improving the economy of Greece the euro countries are providing bridge loan and the tight austerity program introduced in Greece. As the countries are providing loan in a lower rate it is also necessary for them to tight the monetary policy in their countries. As a result the growth would be slow in those countries. As the Euro slow down, as an effect the dollar would go down. Then U.S. also has to tighten its monetary policy and as a result the economy would get hampered (Wagner and Machnowski, 2010, p.2). In a research paper of CEPS the researchers have compared the economic crisis of Argentina in 2001 and the crisis of Greece in 2011. Argentina has defaulted as there was lack of support from the outside of the country. Argentina has tried... The paper tells that the economy of the European Union is facing problem due to this crisis. As the investor is losing their confidence in Euro, the value of the currency is going down. As a remedial measure the governments of the European countries are providing bridge loan and as a result the countries have to tighten the monetary policies. The governments are providing monetary package to the banks which are in problem due to the crisis of Greece. In turn the bank interests come down and the world economy is facing certain problem. As the trade of U.S. is mainly with the European Union countries so the economic crisis of Greece would surely affect U.S. As the European countries are going to tighten their monetary policy for the economic crisis so certainly they would decrease their import and the main trading partner of Euro zone is U.S. The export would get hampered and the economic growth would not be much. As a result U.S. has to tighten its monetary policy and the overall econ omy of U.S. gets hampered. For the short term remedial measures the European Union countries have to provide loan in low cost to Greece and for long term remedial measures the European zone can take some policies like introducing common Euro bonds. The share of the capital would be as per the share of the countries and the interest rate would be provided by the countries would be like they are providing the interest rate they are providing in the domestic market. For the short term measures Greece should restructure its debt using some process like debt swap.
