(June 25, 2009 - Insidermedicine) From New York - According to research in the Journal of Pediatrics, chemicals found in common plastic products may be linked to low birth weight. In a study of 201 newborns, researchers found that those with the highest levels of a phthalate called DBP in their cord blood were 3.5 times more likely to have low birth weight. Phthalates provide flexibility and durability in personal care products, children's toys, and medical devices.

From South Carolina - According to research in the International Journal of Sport Nutrition and Exercise Metabolism, a plant compound may enhance fitness and endurance in nonathletes. In a study of 12 healthy college students, researchers found that supplementation with a purified form of quercetin, which is found in several fruits and vegetables, led to significantly higher increases in peak oxygen consumption and endurance compared to placebo.

And finally, from Sydney - According to research in the British Medical Journal, bone scans may be useless during early osteoporosis drug therapy. In a study of nearly 6,500 post-menopausal women undergoing bisphosphonate therapy, researchers found that bone mineral density scans produced such a wide range of results, that the information was not useful. The researchers conclude that BMD scans during drug therapy may be misleading.
