Urban Gardeners May Be Unaware of Harmful Soil Contaminants
In their quest to consume healthier foods, urban gardeners may actually be unaware of the presence of soil contaminants and how to deal with the issue, putting both gardeners and consumers at risk, according to a new study in PLOS One. Potential contaminants include heavy metals, petroleum products and asbestos, which can result when urban soil is near pollution sources, such as industrial areas and roads with heavy traffic. “Our study suggests gardeners generally recognize the importance of knowing a garden site’s prior uses, but they may lack the information and expertise to determine accurately the prior use of their garden site and potential contaminants in the soil,” said Keeve Nachman, PhD, senior author of the study and director of the Food Production and Public Health Program with the Johns Hopkins Center for a Livable Future. “They may also have misperceptions or gaps in knowledge about how best to minimize their risk of exposure to contaminants that may be in urban soil.” Read more food safety.
Study: 1 in 10 U.S. Adults Have Diabetes
Nearly one in 10 U.S. adults had diabetes in 2010, nearly double the percentage a little more than two decades ago, in 1988, according to a new study in the Annals of Internal Medicine. The study determined that 21 million American adults—or 9.3 percent of all American adults—had either type 1 or type 2 diabetes in 2010. As many as 95 percent of diabetes cases are type 2 cases. "This study also highlights that the increase in diabetes really tracks closely with the epidemic of obesity,” said Elizabeth Selvin, the study's lead author and an associate professor of epidemiology at the Johns Hopkins Bloomberg School of Public Health. “The diabetes epidemic is really a direct consequence of the rise in obesity.” However, the report did find that cases of undiagnosed diabetes were down, indicating new screen techniques are effective. It also found that overall blood sugar control was improved. Read more on obesity.
U.S. Health Care Costs Climbed 3.2% in 2013, to $329.2 Billion
The cost of new medicines, price increases on some branded drugs and patent expirations helped cause the first rise in the overall cost of health services in the United States in three years, according to a new report from IMS Health Holdings Inc., a health care information company. Americans spent a total of $329.2 billion on health services in 2013, up from 3.2 percent from 2012, which had seen a 1 percent decline. However, the report noted that expanded use of cheaper generic drugs—86 percent of all prescription drugs—did help costs from rising even higher. Read more on access to health care.
