Mother in Israel — Unfortunately the fact that you didn’t notice it doesn’t mean students in your seminary didn’t struggle with eating disorders. Anorexia in particular can go for a long time unnoticed, particularly if one is not looking for it. I was in seminary over 10 years ago, and recently found out that one of the girls in seminary with me who I was pretty friendly with was anorexic — I had absolutely no clue at the time, and I was somewhat familiar with eating disorders as we had a few girls in my high school with eating disorders that I knew about.
Bruklyn Jewess — I am not familiar with the research that you quoted, but what I have seen is that the sooner eating disorders are found and treated (and yes, this is a real, serious, and dangerous psychological illness that requires professional help), the better chance at recovery. Therefore educating people to notice the warning signs and get help for their relative/ friend/ student, etc. seems to serve a very important purpose. Particularly in seminary when girls are on their own and don’t have a parent around noticing what a girl is or isn’t eating, having friends who can pick up on these signs can be very helpful.
There is an organization called “Relief” that provides information and referrals targeting the frum community for mental health issues including eating disorders. I don’t know much about the organization, but their website contains a lot of information on these issues and may be helpful to someone with a concern. The site is reliefhelp.org
