Related to this question, I was wondering why nutrition group is limited to nutritionists and medical professionals. I think there is a need for anybody to ask questions about nutrition and get good answers. For instance, Stack Overflow is not limited to professional programmers only; Seasoned Advice is not limited to professional cooks only; Physics group is not limited to professional physicists only. What is the rationale to limit nutrition to professionals only? For instance, I am not a nutritionist or medical professional, can I support this group?
But I definitely agree that nutrition needs to be separate from fitness and exercise topics.

I think this process is taking too long. I recently learned that the co-founder of StackExchange Jeff Atwood started Discourse
a forum platform and I started a nutrition forum using it. If anyone is interested it is here: www.nomilkfor.me
StackExchange platform is not for discussion but for answers. I am not sure which format is better for nutrition. Discussion may be better. There is a satisfaction in finding out something on your own by discussing it with peers.
