Lila,
We are ALL livid about these issues. From the food companies to the doctors who mislead us and gave us antibiotics to cure everything, we realize we've been had. Our government still is giving out bad advice about food. Thanks to people like Dr. Davis and their compelling arguments, this grass roots movement of no grains and no sugar is getting bigger and bigger.
As a people, we are learning to say "NO! I WILL NOT EAT SOMETHING THAT IS MAKING ME SICK!". We are walking with our pocketbooks. We are a passionate group because we feel better and are slowly reversing the health concerns/conditions with better diets which emphasize real food, not the chemical concoctions filling our supermarkets. No, we don't have to become diabetics. We don't have to take blood pressure or cholesterol drugs as we age. Sorry big pharma. Sorry Doctor. Learn to help me get better, not just drug me. No, my future is not as a crippled old lady with dementia and a suitcase of pills for my ailments.
Overall, that bag of popcorn you ate is just a minuscule percentage of your total food intake. Compared to your former diet, you have done remarkably well. It does take a while to reverse many years of eating habits. We are all working towards the same goal of wellness. Next time you go to the movies, your conditioned response of "must buy popcorn or candy" won't be the same.
