Why Women are More Susceptible to Eating Disorders. About 30 million people in the U.S. suffer from eating disorders, 20 million of them women. A study, published in the journal Cerebral Cortex online Oct. 13, 2016, showed that women are more likely than men to have negative feelings about their bodies. When observing their "obese" bodies--using a virtual reality headset--participants in the study experienced brain activity in the parietal lobe, the area of the brain associated with body perception, and activity in the anterior cingulate cortex, the brain area associated with processing subjective emotions, such as fear and anger. The research pinpoints the link between body perception and our emotional responses regarding body satisfaction, said lead author Dr. Catherine Preston, department of psychology, York University, UK.
Rising Trends in Consumption of Specific Supplements. American adults have increased their consumption of supplements such as vitamin D and fish oil, fueled in part by widespread media attention focused on those products, according to a study published in the Journal of the American Medical Association, Oct. 11, 2016. Intake of fish oil increased from 1.3 to 12 percent between 1999-2000 and 2011-2012; vitamin D use increased from 5.1 percent in the earlier period to 19 percent in 2011-2012. Data were obtained from the National Health and Nutrition Examination Survey, based on responses from nearly 38,000 U.S. adults between the periods 1999-2000 and 2011-2012. Researchers found that 52 percent of respondents reported using supplements in 2011-2012, the same number reported between 1999 and 2000. Highest use of supplements was among non-Hispanic white adults (58 percent vs. 29-52 percent of other ethnic groups), among women (58 percent vs. 45 percent of men), and highly educated people vs. those with less than a high school education (65 vs. 37 percent, respectively). Supplement intake also rose significantly with age; 72 percent of people over age 65 take supplements compared to 40 percent of people between ages 20 to 39.
