By Andrew M. Seaman (Reuters Health) – More people in the U.S. are on gluten-free diets even though the proportion of Americans with celiac disease held steady from 2009 to 2014, according to a new study. Despite the fact that gluten-free diets are not known to provide any health benefits for the general population, some people believe they benefit from going gluten-free, said lead author Dr. Hyunseok Kim, of Rutgers New Jersey Medical School in Newark. “People may believe a gluten-free diet is healthier, and the diet is trendy,” Kim said.
