According to the National Institute of Health (NIH) "Brazil nuts may contain as much as 544 micrograms of selenium per ounce. They also may contain far less selenium. It is wise to eat Brazil nuts only occasionally because of their unusually high intake of selenium."
The reasons that selenium is so effective in cancer prevention are uncertain, although it has been speculated that it possesses anti-oxidant properties, "especially when used in conjunction with vitamin C, vitamin E and beta-carotene" and "works to block chemical reactions that create free radicals in the body (which can damage DNA and cause degenerative change in cells, leading to cancer)" (Black 2006). Selenium has also been found to prevent damaged DNA molecules from reproducing, thus preventing the development of tumors as well (Black 2006). This is supported by a University of Arizona-Cornell research team which linked low selenium levels in the blood to increased risk of precancerous neoplastic polyps in the colon (Lang 2010). A Cornell University study conducted in 1995 found that animals fed diets high in selenium had 50% fewer tumors than those fed diets of average selenium content.
However, more recent studies specifically focusing on the ability of...
Minerals According to Lutgen & Tarbuck (2011) "the properties of minerals include crystal shape (habit),luster, color, streak, hardness, cleavage, fracture, and density or specific gravity. In addition, a number of special physical and chemical properties (taste, smell, elasticity, feel, magnetism, double refraction, and chemical reaction to hydrochloric acid) are useful in identifying certain minerals. Each mineral has a unique set of properties that can be used for identification " (p.24). If, as
Minerals In the daily life of an Average American there are numerous materials one encounters which are extracted from minerals that are mined. For the purpose of example, the following materials will be discussed with specific investigation of the minerals mined to supply each of these materials. The materials are limestone, salt, plaster, copper, and graphite, each is encountered on a daily basis and are extracted from certain minerals that are
Mineral Water Deerside is a mineral water firm that is marketing a premium mineral water from the Republic of Georgia that has minerals known to contribute to colon and intestinal health. The high cost of bringing this water from Georgia to the United States, combined with its curative properties, necessitates a premium position in the market, so that that the high cost of shipping the water can be recouped in the
The reason behind the apparent shortage of minerals, and generally of all commodities (petroleum, natural gas, coal, and so on) is the corporate interest of using this artificial situation to enable the profit creation, for the company and its shareholders. The mining industry is estimated to possess raw materials for a maximum period of 20 years. Another example is platinum, subject again to Cohen's theory, that declares that 90%
Perrier Company and Ajax minerals. It discusses the factors that resisted the change in these organization. It also analyzes the effectiveness of the approach adapted by Ajax minerals to manage change resistance. In addition to that, this paper proposes ways through which these organizations can manage change in an effective manner. Ajax Minerals Ajax Minerals is a mining company in the United States of America. Even though the company is operating
Apex Minerals, Australia Mining can be an iffy science due to the fact that indicators of the ore, whichever ore happens to be the focus of the endeavor, can be misled. If this is the case then a mine may have to be abandoned or shafts excavated in new areas around the original to uncover what is known to be there. If the ore is coal, then it is probably
