This question is asked of me all the time. My first thought is to say, "just do it", but I usually refrain because I understand the frustration and the yearning to eat what ever you want - hey, I'm human too.
I have an autoimmune condition and I am working on a plan to significantly reduce the chances of succumbing to disease processes that I have witnessed my dad, grandpa, grandma, mom, aunts and uncles develop as they aged.
I have a high motivation to stay healthy and active with a mind that works well into the next half of my life. That's the key - you have to keep you motivation constantly in front of you.
For some, the motivation is to stay away from bad things...for others, it is to move toward good things. Still others of us are motivated by a combination of both.
Autoimmune processes, like autoimmune thyroid (Hashimoto's and Graves), celiac disease, Parkinson's disease, multiple sclerosis, rheumatoid arthritis, diabetes and a host of others can be SIGNIFICANTLY affected by diet. Not only that but heart disease, peripheral artery disease or just being over-fat are directly related to diet.
The bottom line is you just have to find your motivation and keep that squarely in your mind....and speaking of that....use your mind, not your tongue or old habits to determine what you can or cannot eat any longer for your health's sake.
I was just on vacation to Jamaica for the first time. I can honestly say that both my wife and I were able to totally stay on our chosen health restoration/supporting diet while we were away. The picture at the beginning of the article was just one example of a breakfast I had. Whenever we went to a restaurant we would first browse the menu and determine things we could most safely eat and then we tweaked recipes with the help of the chef and our waiter or waitress. Restaurants these days are more than accommodating. Since we ate out every day (all inclusive) we also were sure to take our GlutenFlam enzymes to break down inadvertent gluten. When I eat out, I take 3 capsules just before I start eating.
I can say, it feels good to have some control of your health's destiny and to choose to be an active participant in the process of staying healthy. You can choose to do it too!
