I came across this article today in the Toronto Star, a Canadian paper about eating disorders and genetics. Although this area of research has become more known and accepted, I think it's still important to emphasize, especially when socio-cultural headlines dominate the media. This article gives a nice outline into how the studies evolved and what researchers are looking for today.
This spring, a large National Institutes of Mental Health sponsored study will wrap up. This specific gene study analyzes samples of DNA from families who have two or more members with anorexia. I'm interested to see the outcomes of this study as it could shed more light into the role genetics play in eating disorders and its development.
