MILK WARS UPDATE Kraft Foods has agreed to stop running ads encouraging people to "burn more fat" and lose weight by consuming more dairy products. That message and similar ones from General Mills, Dannon and other food makers have provoked legal action by the Physicians Committee for Responsible Medicine, which labeled the ads deceptive. The group dropped Kraft from its lawsuit following the company's announcement.

Researchers are divided on what role dairy products might play in childhood overweight and obesity, which have risen over the past two decades as milk consumption has dropped. One large study this year found that children who drink more than three servings of milk a day are more likely to be overweight. But other studies have produced conflicting evidence.

BAD TIME FOR A HEART CRISIS Heart attack sufferers who arrive at hospitals on nights and weekends wait longer for a lifesaving artery-clearing procedure than patients who arrive during business hours. The extra wait for an angioplasty increases patients' risk of death by about 7 percent, found a study of 68,000 patients in the Journal of the American Medical Association.

Guidelines advise that patients receive an angioplasty within 90 minutes of entering a hospital. The study showed that four out of 10 patients waited more than two hours.

Experts said the findings were troubling because two-thirds of heart attack patients show up at hospitals at night or on weekends. More after-hours staff members are needed in cardiac catheterization labs, the study authors said.
