I don't know if this will help any, but I will give my two cents. I am finding almost everyone completely against being primal. I actually avoid saying I eat primal because no one gets it. I just tell them I don't eat wheat, grains, or any sugars. It seems to not have as much shock value I guess. Everyone in my family thinks its crazy also NOT to eat grains. My SO was the most resistant and always ALWAYS argued that grains and legumes should be eaten on a daily basis. It wasn't until he SAW the changes in me, that he started to believe. I don't really have much for health issues, and I don't know about you but maybe if you are around them a lot, they will see the changes too and start to wonder. If you are able anyway. I think its probably the best way to spread the primal word, but allowing others to see the changes in yourself.
It's not working on my mom yet though, I hope it does soon. She has severe osteoporosis, bone spicules in her spine, arthritis in her neck/back and constantly suffers from severe pain and nasty migraines. She recently got some quartizone shots in her neck, which is helping her neck a bit, but I really think that if she could try eating how I do for a week, she'd feel better.
My dad too, was told (by is doc) to eat more fruits ( not specifically berries, just all fruits) less red meat, more fish ( which is good) and more grains....sigh. He is type 1 diabetic and had a small TIA a few weeks ago. I think he could benefit from eating primal as well. Unfortunately, my parents are set in their way. ( you prob didn't need that whole story, but I couldn't help but throw it out there) Because I know how you feel about wishing your loved ones would adapt to your lifestyle.
