A couple of points for your consideration.
1) Most here are not doing SCD. I have no idea but I would think about 10 % (just a blind guess).
2) Some think it really helps (Like me) and others not so much
3) You need to read Breaking the VIcious Cycle and in it it says that if you are not going to be fanitically compliant not to bother
4) The site below is a link to what is legal and what is not
I agree with you 100%. "I might as well take care of my diet and how can it be bad." I have never eaten so healthy. And even though I eat a lot, I have dropped from 205 to 162 and this is when I have been on prednisone and entrocort and a couple of other steriods.
I hope some of the other folks here both supporters and those that do not think this helps responds to your post so you get both sides of the story.
Take care and let us know your decision
