According to very recent study published (Feb, 2008) in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine, as opposed to expected, vitamin supplements do not protect against lung cancer.
Rate of lung cancer development was analyzed over four years and its correlation with current and past vitamin usage, smoking, and other characteristics such as demography and medical history was explored.
Citing Dr. Slatore, the researchers of the published article: "Our study of supplemental multivitamins, vitamin C, vitamin E and folate did not show any evidence for a decreased risk of lung cancer." Also, Dr. Slatore says that the participants with increased intake of vitamin E had slightly higher risks of lung cancer.
Further information in the article: Long-Term Use of Supplemental Multivitamins, Vitamin C, Vitamin E, and Folate Does Not Reduce the Risk of Lung Cancer by Christopher G. Slatore, Alyson J. Littman, David H. Au, Jessie A. Satia, and Emily White published in American. Journal of Respiratory and Critical Care Medicine. 2008; 177: pp. 524-530. |

sbestos is a group of minerals with long, thin fibrous crystals. The word "asbestos" is derived from a Greek adjective meaning inextinguishable. The Greeks termed asbestos the "miracle mineral" because of its soft and pliant properties, as well as its ability to withstand heat.
Asbestos became increasingly popular among manufacturers and builders in the late 19th century due to its resistance to heat, electricity and chemical damage, sound absorption and tensile strength. When asbestos is used for its resistance to fire or heat, the fibers are often mixed with cement or woven into fabric or mats. Asbestos is used in brake shoes and gaskets for its heat resistance, and in the past was used on electric oven and hotplate wiring for its electrical insulation at elevated temperature, and in buildings for its flame-retardant and insulating properties, tensile strength, flexibility, and resistance to chemicals.
The inhalation of asbestos fibers can cause serious illnesses, including mesothelioma and asbestosis. Since the mid 1980s, many uses of asbestos are banned in many countries. (From wikipedia) |
