Pros and Cons of Weight Reducing Diets Essay -- Health Nutrition Diet

Pros and Cons of W octet Reducing DietsThe article Health Advantages and Disadvantages of Weight-Reducing Diets A Computer Analysis and Critical Review outlines eight diets that were examined and how the researchers and doctors looked at the potential long term effects of each one. The diets examined were Atkins, Protein Power, Sugar Busters, Zone, ADA Exchange, High-Fiber Fitness, Pritikin and Ornish. The research team created formulas using computer software, menu plans with recommended snacks and looking at the food pyramid to estimate coronary heart disease (a disease of the heart and arteries that blocks blood flow to the heart). They found that diets high in protein and fat, protein being a complex organic molecule necessary for the proper functioning of an organism and low in carbohydrates, an organic compound that serves as a major power source, produce a greater risk for coronary heart disease and diabetes. Over 50% of Americans are overweight. This has led to the creation of many different diets. rough of these diets promote healthy eating and long-term weight loss while others are just fad diets with unsafe recommendations. It is suggested by expert panels that people should follow through about 30% fat, from which only 10% can be saturated fat (a fat of animal origin) and less than 300 mg. of cholesterin daily. Cholesterol is a white substance found in animal tissues that serves the cell membranes. The first thing the researchers did was to identify which diets were currently popular. They then looked at those diets that have been around for a long time. Each diet examined was different. The Atkins diet states that a high-fat ... ...tein Power diets are very high in total and saturated fat compared to current dietetical guidelines. Long-term uses of these diets for weight maintenance are likely to significantly increase cholesterol concentrations and risks for coronary heart disease. Diets that are higher in carbohydrates and fiber truly lower these risks. High fat diets do have short-term weight loss but the potential hazards for worsening the risk for heart disease and cholesterol problems override the short-term benefits.

Cottam Summary Report :: Archaeology Essays

Cottam Summary ReportDuring 1993 an archaeological evaluation was conducted at the Anglian commit at Cottam, North Humberside, under the auspices of the York ring Project, Department of Archaeology, York University. Fieldwalking was carried out in January and February, and Dr J.D.Richards and B.E.Vyner directed limited excavations during July and August. The purpose of this note is to provide an interim summary, in advance of the main publication which will come out of the closet in the Yorkshire Archaeological Journal in due course. The site lies on arable land high on the Yorkshire Wolds nigh 10 miles from the coast, in the parish of Cottam (NGR 49754667). It was sight in 1987 by metal detector enthusiasts and has subsequently been intensively worked, yielding a rich collection of predominantly Middle Saxon metalwork. The metalwork finds hit been systematically plotted, and published in the Yorkshire Archaeological Journal (Haldenby 1990, 1992 and forthcoming), although the l ocation of the site has hitherto been withheld as a contribution to its protection. To date the published finds include some 30 simple pins, 26 strap-ends, 8 lead spindle whorls, 40 iron knife blades, 14 ninth-century stycas, plus a Jellinge-style brooch and a Scandinavian bell. Two main concentrations of metal finds have become apparent, and these can be seen to be roughly coterminous with two concentrations of crop marks. The date range of the artefacts suggests that the site was in use for much of the 8th and 9th centuries AD. During April 1989 fieldwalking was undertaken for Humberside Archaeological Unit by Peter Didsbury and members of the East Riding Archaeological Society (Didsbury 1990), leading to the recovery of beast bone, prehistoric flints and Roman and medieval pottery, as well as Anglian pottery. The site at Cottam provides an opportunity to fill some of the gaps in our knowledge of activity in Yorks hinterland during the 8th and 9th centuries. From the surface find s it is apparent that it belongs to a new category of site in Humberside and Yorkshire producing rich Middle Saxon and Viking Age metalwork, which has not so far been excavated. The aim of the evaluation, therefore, was firstly, to establish the extent and survival of archaeological deposits secondly, to identify the sequence of 8th and 9th- century activity thirdly, to establish the relationship of the metalwork and the crop-marks and lastly, to go under the nature of the 8th and 9th- century activity. Fieldwalking confirmed the picture derived from the distribution of metal- detector finds of two concentrations of post-Roman activity, suggesting there was an Anglian nucleus towards the centre of the field, and a subsequent shift to the atomic number 10 during the Viking Age.
