IOM: Low Sodium Intake May Also Cause Adverse Health Effects
While multiple studies have shown that the average daily sodium intake for U.S. adults is far too high, lowering the intake too much could also lead to health problems, according to a new report from the Institute of Medicine. The average daily intake is 3,400 mg, or about 1.5 teaspoons. The Dietary Guidelines for Americans call for a maximum of 2,300 mg, and even 1,500 mg for certain demographics. However, there is also some evidence suggesting low sodium levels could be harmful to people such as those with mid- to late-stage heart failure. “These studies make clear that looking at sodium’s effects on blood pressure is not enough to determine dietary sodium’s ultimate impact on health,” said committee chair Brian Strom, George S. Pepper Professor of Public Health and Preventive Medicine at the University of Pennsylvania Perelman School of Medicine. “Changes in diet are more complex than simply changing a single mineral. More research is needed to understand these pathways.” Read more on heart health.
CDC Guidelines Help Cut Bloodstream Infections from Dialysis
Following the U.S. Centers for Disease Control and Prevention’s (CDC) prevention guidelines helped reduce overall bloodstream infection due to dialysis by 32 percent and vascular access-related bloodstream infections by 54 percent, according to a new study in the American Journal of Kidney Disease. There are approximately 37,000 bloodstream infections each year related to dialysis with central lines; in 2010 about 380,000 U.S. patients used hemodialysis for treatment of end-stage kidney disease, with 8 in 10 of utilizing central lines. "Dialysis patients often have multiple health concerns, and the last thing they need is a bloodstream infection from dialysis,” said CDC Director Tom Frieden, MD, MPH. “These infections are preventable. CDC has simple tools that dialysis facilities can use to help ensure patients have access to the safe healthcare they deserve.” Read more on prevention.
Study: Teen’s Use of Smokeless Tobacco Steady Over Past Decade
Despite a myriad of efforts to combat tobacco use by U.S. teens, their usage rate of “smokeless” tobacco products such as chew or snuff has remained steady since 2000, according to a new study in the Journal of the American Medical Association. The rate was 5.3 percent in 2000 and just barely lower in 2011, at 5.2 percent. While younger teens in the 9-14 age range have decreased their use, those in the 15-17 range have increased. The study suggests that the relatively low prices of smokeless tobacco products may be a contributor. About 9 million Americans used smokeless tobacco in 2012. Read more on tobacco.
