I think that for you, this may definitely be a factor. Everyone is so individual with this. On the issue of food additives in France, let me tell you that may be possible since the food for the average citizen there us pretty unexciting. I don't care if I ever see another baguette! LOL Their selection of vegetables and meats were limited since meat is very expensive. We did eat a lot less processed food and heavy oils like mayonnaise. I never did find any peanutbutter! The first thing we did when we got back to the states was go out for a good hamburger! I wish you good health; it is cheaper to eat at home anyway!
