The dietary requirements necessary to maintain a healthy Essay

The dietary requirements necessary to maintain a healthy - Essay Example Digestion breaks down proteins into amino acids. Amino acids are of three categories – essential, nonessential and conditional amino acids. Essential amino acids are nine – â€Å"Histidine, Isoleucine, Leucine, Lycine, Methionine, Phenylalanine, Threonine, Tryptophan and Valine† – and can only be obtained from food intake. Nonessential amino acids are four – â€Å"Alanine, Asparagine, Aspartic Acid and Glutamic Acid† – and are made by the body by breaking down essential amino acids. Conditional amino acids are eight in number – â€Å"Arginine, Cysteine, Glutamine, Glycine, Ornithine, Proline, Serine and Tyrosine† – and are not viewed as essential. They are only needed in times of illness. There are many sources of proteins: all types of meat, all types of beans, nuts and seeds, soy proteins products, dairy products and eggs. Intake of proteins should be regulated. This is because a high level of proteins may overwork the kidney. Meat and eggs intake should also be watched as these products contain high levels of cholesterol. Accumulation of cholesterol in the body is a risk factor for heart disease. In severe deficiency of proteins, Kwashiorkor is likely to develop. The recommended daily intake of proteins is â€Å"2 to 3 ounces of cooked lean meat, poultry, or fish;  ½ cup of cooked dried beans; 1 egg, 2 tablespoons of peanut butter, or 1 ounce of cheese†. Carbohydrates Carbohydrates are very important as they provide the fuel to the body after being broken down to glucose which is oxidized to release energy. Carbohydrates are of two main types – complex and simple carbohydrates. Complex carbohydrates include starch and dietary fiber. Complex carbohydrates must be broken down to glucose for the body to utilize. Starch is contained in foods such as breads, cereals and vegetables. Dietary fiber is of two categories: soluble and insoluble fiber. Soluble dietary fibers include oatmeal, nuts and seeds among others while insoluble dietary fibers include brown rice, barley, fruits among others. Simple carbohydrates are those that naturally have sugars, for instance, fruits, milk products among others (Centers for Disease Control and Prevention 2012). Dietary fibers are recommended over refined meals. Removing the external cover of grains converts them into refined foods. The diagram below show the recommended amount of grams required daily (Centers for Disease Control and Prevention 2012).

Deficiency in carbohydrates in the body forces the body to burn fats and proteins to use as a source of energy (Centers for Disease Control and Prevention 2012). This deficiency therefore leads to malnourished people. However, in severe cases of carbohydrate deficiency, marasmus is likely to develop. Marasmus develops when there is severe malnutrition. Lipids Lipids are needed in the body to transport the fat soluble vitamins, supply energy and provide fatty acids. Lipids exist in various forms; if a lipid is a liquid at room temperature then it is called oil, if it is solid at room temperature t hen it referred to as fat. Lipids are hydrolyzed to release glycerol, fatty acids, diglycerides and monoglycerides. Fatty acids are particularly important in the

Visual analysis paper - Coursework Example Rococo or late Baroque style later came in the 18th century and impacted on art’s sculpture, painting, decoration and interior design. Giotto di Bondone’s â€Å"Madonna Enthroned† created in 1300 by an Italy using the Rococo technique and Garofalos "Madonna and Child in Glory" created in 1935 in Pinacoteca Capitolina are two distinct but closely related masterworks whose exploration can be quite enthralling. This paper shall candidly and comprehensively analyze the two artworks with the predominant aim of determining how similar or different they are in terms of style and the thematic implications or the messages that the artists envisioned to deliver to the audience. Giotto’s â€Å"Madonna Enthroned†, drawn on tempera on panel, patently indicates that the art was painted by an iconic painter, probably cultured and trained in Greek but working in Italy or for a western promoter. This can be derived from the way the artist blends byzantine with western elements in the entire masterpiece. The folds of the cloths are defined by a byzantine concord and the image’s composition is modeled on the Hodegetria, the virgin, who points at the child to show that he is the way, the truth and the light. Additionally, the son, Jesus, gives the Western signs of blessings. The halos on the side of the child are decorated with floral patterns that are popular in Italy. Moreover, the image has a 3-D view, particularly in the virgin’s thrown, to indicate western influence. The artist intentionally uses a virgin with archangels’ majestic regalia and red shoes in the elaborate throne to accentuate Mary’s role as the crowned hea d of Heaven. In the artwork, the golden background connotes the heavenly kingdom implying that the artist knew quite well how gold was treasured in the then community due to its economic value and its imperative role in determining one’s social and economic status.
