It is everyone's impulse to want to help others and that is commendable. After years and years of doing this, I finally realized that people usually have to discover these things for themselves. So now all I do is talk about it if the topic comes up and how it works for me and I find it interesting. I try not to approach it as recommendations for other people, that can backfire. I read a quote that stuck, forgot whom it was by.... "Preach not to others what they should eat, but eat as becomes you, and be silent"
just my 2cents
