There is a lot of information out there. Some of it good, some of it bad. These are some of my favorite resources and I'll be adding more as I find them.
Paleolithic Diet
This is the site that really got me thinking about the link between nutrition and my disease. It has a ton of information and Mark often references actual scientific studies.
Robb has a lot of good information and tends more towards "sciency" explanations.
A great site that offers up a 30 day super clean eating challenge. I highly recommending doing a Whole30 and joining their forums.
Paleo Recipes
Melissa has a ton of great recipes as well as good everyday advice. She also deals with a chronic condition.
George always posts great recipes and usually has some awesome giveaways going on.
Nom Nom Paleo
A good resource for paleo recipes. Some of her recipes are a little bit fancier regarding cooking techniques, but you learn a lot.
This is a great resource for hiking trails around Vancouver.
J-pouch and Colitis
A lot of good information about living with a j-pouch and they have a good forum as well.
