Essay on Nutrition


Introduction
The article is discussing the different types of nutrients and their relative importance to athletes in particular to maintain their stamina and to effectively pursue their routine and carry out strenuous energy consuming activities. Some of the vital nutrients that a human body requires in order to carry out the vital processes of life include carbohydrates, proteins, fats, vitamins, water and trace elements.
Fundamental Nutrients and Requirements for Athletes
Some of the fundamental nutrients such as carbohydrates and fats are crucial as prime energy providing food substances to the body for example carbohydrates are required in the form of glucose so that it can be used for respiratory substances and as a prime energy requirement for red blood cells and brain cells of the human body. Fats are also important for energy serving processes whereas proteins are important for the repairing and synthesis of vital substances such as enzymes and some key hormones such as insulin and glucagon. The amount and percentage of these nutrients required so that it may constitute a balance diet of an individual are influenced by the profession that the person is involved with and the kind of work that he does. A person such as an athlete requires a constant and undisturbed supply of carbohydrates throughout the day in varying percentages in order to replenish the energy that he has lost in the form of sweat and strenuous activity during play.
Nutritionists estimate that they require up to 3-5 grams of carbohydrate/lb body weight, most importantly in order ensuring that the red blood cells are constantly supplied with glucose and these cells in turn facilitate the release of oxygen from hemoglobin. Apart from this 0.55-0.75 grams of protein are required by athlete in order to compensate for the wear and tear that takes place in their body during their game and also to ensure that the hormonal balance is not disturbed due to excessive dehydration taking place in the body. Fats on the other hand are consumed in the least amount as 0.5 gram/lb body weight, mainly because excessive intake of fats and cholesterol diet may facilitate the deposition of atheromatous plaque in blood vessels causing which in turn causes blockage of blood vessels reducing the amount of blood flow and increasing the chances of heart diseases suffering. (Robert, 1999)
Nutrition experts further suggest that they need to have a high diet of carbohydrate rich cereals, protein rich vegetables and low fat minerals as an essential part of their diet. Most athletes in order to raise their body and physical stamina level move towards mountainous regions of high altitude. This is because at high altitudes the atmospheric pressure or the partial pressure decreases as a result of which the depth of inhalation increases, the body responds to this change by increasing the number of red blood cell production in the body so that the concentration of hemoglobin and blood in the blood increases. It is further suggested that athletes require 0.75 grams/lb of body weight after 30 minutes of arduous exercise and another 0.75 grams/lb of body weight after two hours.
The American College of Sports Medicine advises athletes to consume over 16 ounce of energy fluid before exercise and 16 ounce of fluid after exercise. In addition to this they need to replace over 80% of their weight lost before next exercising session goes underway. (Ron & Burke, 2002)
Conclusion
In order to effectively pursue their career without suffering from any harmful diseases and health problems it is important that athletes strictly adhere to their formulated diet plans and take minor amounts of nutrients that may prove harmful to their health in the long-run, but scrupulously follow some of the essential nutrients that are required for the vital functions of their body.




erm� # i M XlN NATO or the US security forces.
The number of casualties is constantly on the surge with 2010 being the year registering the highest number of reported deaths of soldiers. Furthermore the operation has also fostered rifts in the civil and military relations of US which manifested itself in the retrenchment and axing of General McChrystal. Money and finance is constantly being pumped but the outcomes are nowhere to be seen.
Hence it is more or less a requirement and demand of time that NATO and US forces to devise cohesive strategies through the help of local population and the Afghan government devise a proper work plan structure through which they can ensure their proper withdrawal from the region and also shield themselves from the malignancy and defamation that the Red Army faced in 1979. (Morellie and Paul, 2009)
One of the initial steps that can be taken in this context is to establish and initiate negotiations with the rather diplomatic wing of Talibans.
