Drink brewed tea to avoid tooth erosion

Today, the average size soft drink is 20 ounces and contains 17 teaspoons of sugar. More startling is that some citric acids found in fruit drinks are more erosive than hydrochloric or sulfuric acid—which is also known as battery acid. These refined sugars and acids found in soda and citrus juice promote tooth erosion, which wears away the hard part of the teeth, or the enamel. Once tooth enamel is lost, it's gone forever. There is a beverage that does not produce such irreversible results. When deciding between the many options available, the best thing to drink is brewed tea, according to a study in the July/August issue of General Dentistry, the clinical, peer-reviewed journal of the Academy of General Dentistry (AGD). more  

'Deranged calcium signaling' contributes to neurological disorder, UT Southwestern researchers find

Adiponectin is a metabolic link between obesity and bone mineral density

Researchers at the University of Toronto, Faculty of Medicine, Toronto, Canada, have discovered that adiponectin, a protein secreted from adipocytes, is a metabolic link that can explain, in part, the known positive relationship between obesity and both bone mineral density and reduced susceptibility to fractures. This study appears in the December issue of Experimental Biology and Medicine. Circulating adiponectin levels are significantly lower in obese humans and rodent models than in lean controls. It is known that excess body weight and elevated body mass index are strongly correlated with high bone mineral density, and that weight loss is associated with loss of bone mineral density and increased risk of fractures. However, the mechanism for this relationship is unclear. more
