EFSA sets lower tolerable intake level for cadmium in food - 0 views

Matti Narkia on 28 Mar 09

The European Food Safety Authority's Panel on contaminants in the food chain has set a reduced tolerable weekly intake (TWI)[1] for cadmium of 2.5 micrograms per kilogram of body weight (µg/kg bw), based on an analysis of new data. The TWI is the level at which adverse effects are not expected. Average dietary exposure to cadmium for adults across Europe is around this level. Some population groups - vegetarians, children, smokers and people living in highly contaminated areas - can have a higher level of exposure up to twice the TWI. However, the Panel concluded that even for these groups the risk of adverse effects would be very low. The Panel concluded that current exposure to cadmium at the level of the population should be reduced.

Long-term ozone exposure may increase risk of death from respiratory causes - 0 views

Matti Narkia on 13 Mar 09

MedWire News: Long-term exposure to ozone is associated with an increased risk of death from respiratory causes, researchers have found.\n\nA two-pollutant model in the study, published in the New England Journal of Medicine, showed that levels of fine particulate matter less than 2.5 µm in diameter (PM2.5) were associated with death from cardiovascular causes, whereas increased ozone concentrations were associated with an increased risk of death from cardiopulmonary causes.

Vitamin D - Linus Pauling Institute at Oregon State University - 0 views

Matti Narkia on 25 Feb 09

Vitamin D is a fat-soluble vitamin that is essential for maintaining normal calcium metabolism (1). Vitamin D3 (cholecalciferol) can be synthesized by humans in the skin upon exposure to ultraviolet-B (UVB) radiation from sunlight, or it can be obtained from the diet. Plants synthesize ergosterol, which is converted to vitamin D2 (ergocalciferol) by ultraviolet light. Vitamin D2 is less active in birds than vitamin D3 and may also be less active in humans (2). When exposure to UVB radiation is insufficient for the synthesis of adequate amounts of vitamin D3 in the skin, adequate intake of vitamin D from the diet is essential for health.

SAN DIEGO, May 20 -- The effects of exposure to secondhand smoke in childhood may persist for decades, a researcher said here. In a large cohort of nonsmokers, early signs of emphysema were noticeable on CT scans among those who had lived with one or more smokers in childhood, according to Gina Lovasi, Ph.D., of Columbia University. Those signs -- a significant increase in the number of "air-like spaces" -- were not accompanied by any clinical symptoms, Dr. Lovasi said at the annual meeting of the American Thoracic Society.

Do you live in a big city or an area where you are sometimes forced to inhale car and truck exhaust? If so, you should strongly consider using a face mask, because exhaust causes arteries to lose their flexibility. Researchers writing in the journal Particle and Fibre Toxicology found that exposure to engine pollution resulted in arterial stiffness in a group of healthy volunteers.

This is because exciting new research indicates that vitamin D-whether produced in the skin as a result of exposure to ultraviolet radiation (from sunlight or sun lamps) or obtained from supplementation with cholecalciferol (vitamin D3)-may help cancer patients. However, the research is far from complete.

ScienceDaily (Feb. 10, 2009) - Vitamin D is significantly associated with muscle power and force in adolescent girls, according to a new study. Although vitamin D is naturally produced in the body through exposure to direct sunlight, vitamin D deficiency has become widely common in the United States. Vitamin D deficiency has been shown to have a significant negative impact on muscle and bone health, and can lead to conditions including osteoporosis and rickets.
