Environmental Exposure to Particulates May Damage DNA in as Few as Three Days (ScienceDaily)

Exposure to particulate matter has been recognized as a contributing factor to lung cancer development for some time, but a new study indicates inhalation of certain particulates can actually cause some genes to become reprogrammed, affecting both the development and the outcome of cancers and other diseases… More

 

BPA Chemical Leaches from Plastic Drinking Bottles into People (PhysOrg)

A new study from Harvard School of Public Health (HSPH) researchers found that participants who drank for a week from polycarbonate bottles, the popular, hard-plastic drinking bottles and baby bottles, showed a two-thirds increase in their urine of the chemical bisphenol A (BPA). Exposure to BPA, used in the manufacture of polycarbonate and other plastics, has been shown to interfere with reproductive development in animals and has been linked with cardiovascular disease and diabetes in humans. The study is the first to show that drinking from polycarbonate bottles increased the level of urinary BPA, and thus suggests that drinking containers made with BPA release the chemical into the liquid that people drink in sufficient amounts to increase the level of BPA excreted in human urine… More

 

“Super Size” Diet Increases Insulin Resistance (Science News)

Too much fast food could put people on a fast track to diabetes, a new study suggests.

Just one month on a fast food diet was enough to alter the ability of fat cells to respond to insulin, researchers from Linköping University in Sweden reported online April 30 in Molecular Medicine. The inability to respond properly to insulin, called insulin resistance, is a hallmark of type 2 diabetes… More

 

Excessive Cola Consumption Can Lead to Super-Sized Muscle Problems Warn Doctors (PhysOrg)

Doctors have issued a warning about excessive cola consumption after noticing an increase in the number of patients suffering from muscle problems, according to the June issue of IJCP, the International Journal of Clinical Practice.

“We are consuming more soft drinks than ever before and a number of health issues have already been identified including tooth problems, bone demineralisation and the development of metabolic syndrome and diabetes” says Dr Moses Elisaf from the Department of Internal Medicine at the University of Ioannina, Greece.

“Evidence is increasing to suggest that excessive cola consumption can also lead to hypokalaemia, in which the blood potassium levels fall, causing an adverse effect on vital muscle functions”… More

 

Valley People Seek Alternative Ways to Deal with Stress ( Fresno Bee )

Yoga studios, meditation classes and the offices of massage therapists and acupuncturists are crowded with folks who have lost jobs and homes – or worried about losing them – and who want some relief from the stress… More
