Studies Linking Cancer, Nutrition Can be Tricky to Analyze
A new report in the American Journal of Clinical Nutrition casts doubt on many other reports linking certain foods to increases or decreases in cancer risk. When people worry about certain conclusions based on weak or misinterpreted evidence, that can take focus away from foods and actions with more evidence supporting their links—or lack of links—to cancer. The new research demonstrates the need to rethink how to analyze and report the science. "We have seen a very large number of studies, just too many studies, suggesting that they had identified associations with specific food ingredients with cancer risk," said John Ioannidis, MD, from the Stanford Prevention Research Center in California, to Reuters. "People get scared or they think that they should change their lives and make big decisions, and then things get refuted very quickly." Read more on cancer.

Study: Sleep Disorder Linked to Later Heart Problems
Treating the sleep disorder obstructive sleep apnea may help prevent heart issues such as high blood pressure, heart rhythm disorders, heart attack and stroke, according to new findings presented at the annual meeting of the European Association of Cardiovascular Imaging in Athens, Greece. Researchers found the sleep disorder causes the same sort of cardiovascular damage as that found in people with diabetes. "Patients should realize that behind snoring there can be a serious cardiac pathology and they should get referred to a sleep specialist," said Raluca Mincu, MD, of Bucharest, Romania, in a European Society of Cardiology news release. "If they are diagnosed with obstructive sleep apnea, they are at increased risk of cardiovascular disease and need to adopt a heart-healthy lifestyle to reduce that risk." Read more on heart health.

Study: People Who Think They Ate More Are Less Likely to be Hungry Later
Think you had a big meal? Even if you didn’t, simply thinking so can make you less hungry later, according to a new study in the journal PLoS One. Researchers from the University of Bristol in England secretly altered the amount of soup eaten by volunteers, with those thinking they had larger portions—even when they didn’t—less likely to be hungry several hours later. The findings could have a major impact on how to control portions and calorie intake. Read more on nutrition.
