A new CDC study that says America's obesity rates are actually climbing was something of a gut punch for health advocates and for anyone concerned about the country's long-term health care costs. It's bad news, especially in light of the fact that Americans' diets have been improving, ever so slightly, as tastes change, schools have stricter standards, restaurants offer healthier options and food makers reformulate their products. The prevalence of obesity was found to be higher among non-Hispanic whites, non-Hispanic blacks, and Hispanic adults and youth than among non-Hispanic Asian adults and youth.

The European Union's food regulator, meantime, may have found that glyphosate is unlikely to cause cancer, but the EPA is still looking at the widely used herbicide's health effects. The agency is in the process of a regular reassessment of the chemical with the aim of issuing draft human health and ecological risk assessments in the next several months. A final decision on the ongoing use of the pesticide is expected in 2017, after federal wildlife services ensure the agency's conclusions won't result in harm to any endangered species.
