(July 31, 2009 - Insidermedicine) From London - According to research in the American Journal of Clinical Nutrition, organically produced foods may be no more nutritional than conventionally produced foods. In a review of 50 studies, researchers found no difference in nutrient content between organic and conventional foods. Organic foods are those grown on farms that limit pesticide and herbicide use in crops, and drug use in livestock.

From California - According to research in the American Journal of Respiratory and Critical Care Medicine, atmospheric ozone levels currently considered safe under federal regulations can impair lung function in healthy individuals. In a study of 31 adults, researchers found that inhalation of 70 parts per billion ozone for 6.6 hours led to a significant reduction in the volume of air that participants could forcibly exhale.

And finally, from France - According to the International Agency for Research on Cancer, tanning beds are a high cancer risk. Citing case-control studies and a meta-analysis, researchers have raised the classification of tanning beds into the highest-risk cancer category. Research has shown that those who begin using tanning beds before age 30 have a 75% higher risk of cutaneous melanoma than the general population.
