FDA Takes Another Step to Reduce Consumption of Trans Fats
The U.S. Food and Drug Administration has taken another step to reduce American’s consumption of trans fats with a preliminary determination that partially hydrogenated oils (PHOs) are not “generally recognized as safe” for use in food. PHOs are the primary dietary source of artificial trans fat in processed foods. Up next is a 60-day comment period to collect more information and input on exactly what it would take for food manufacturers to reformulate products so that they do not include PHOs. “While consumption of potentially harmful artificial trans fat has declined over the last two decades in the United States, current intake remains a significant public health concern,” said FDA Commissioner Margaret A. Hamburg, M.D. “The FDA’s action today is an important step toward protecting more Americans from the potential dangers of trans fat. Further reduction in the amount of trans fat in the American diet could prevent an additional 20,000 heart attacks and 7,000 deaths from heart disease each year—a critical step in the protection of Americans’ health.” Read more on food safety.
Lack of Light Disrupts Sleep Cycles During Hospital Stays, Increases Patient Discomfort
Hospital stays may be even more uncomfortable for most patients than necessary because of an overall lack of adequate light, according to a new study in the Journal of Advanced Nursing. The small study found that lower levels of daytime light exposure were connected to worse mood, as well as more fatigue and pain, in patients. The poor light interfered with their bodies’ ability to adopt a normal sleep-wake cycle. Researchers found the lowest levels of daytime light exposure were tied to worse mood and more fatigue and pain among patients, compared to those whose rooms were better-lit during the day. "Until now, no one has looked at the associations among light and outcomes such as sleep, mood and pain experienced in the hospital," said Esther Bernhofer, lead author of the study and a nurse researcher at the Cleveland Clinic's Nursing Institute. "This study forms a basis for testing future lighting interventions to improve sleep-wake patterns, mood and pain in hospitalized adults.” Read more on mental health.
Study: No Link Between IVF, Increased Risk of Cancer in Kids
Despite years of concerns, a new study on in vitro fertilization (IVF) found no link between the conception technique and an increased risk of cancer in children. The findings were published in the New England Journal of Medicine. Researchers analyzed data on more than 106,000 children born through assisted reproduction between 1992 and 2008, finding the risk of them developing cancer was "the same as naturally conceived children," according to lead researcher Alastair Sutcliffe, MD, a specialist in general pediatrics at the University College London. More than 5 million children have been born through IVF since the first successful birth in 1978. "This study is extremely reassuring and should relieve anybody's anxiety about IVF," concluded Lawrence Grunfeld, MD, an associate clinical professor of obstetrics, gynecology and reproductive science at the Mount Sinai Icahn School of Medicine, in New York City.
