Why will some people (quite a few) refuse to 'think outside the box'? As in, blindly obeying the government and media pronouncements about what we should eat, and refusing to see the validity of the research re a plant based diet? What is it about many people that they feel so threatened? Are they just generally close minded about most things?
My personal opinion in living with a similar situation is that it isn't about boxes or blindly obeying at all. It is much more about feeling threatened that they might not be able to live the way they want and enjoy the food they enjoy. That is definitely the case in my house and with many of my friends and relatives. My husband often tells me "but I am not sick like you are." Then he offers up examples of people that eat the SAD that lived a long and 'healthy' life. My husband loves food. Most people I know... LOVE food. Few are willing to change. Most would rather just take a pill and eat what they want. (in my experience)
I have shared movie after movie with family members, book after book... tons of information and my own example of healing... yet... they just smile and say "that is great for you, but I am not doing it." And some of them are very, very sick. Some have died.
I am learning to just do what I need to do for me and to quit focusing on anyone else. It has been a bumpy road for me. I still speak and share as I go along... that will never stop, but I don't put nearly as much energy into worrying about the health of others anymore. People can be very set in their ways and unfortunately, from what I see... they rarely make changes until the have to, and even then they would rather be medicated and live with a treatment plan.
