I lived in France for four years. I loved the local food and miss it dearly now. That being said, when I would return from extended trips to the US (eating lots of sugary food), it would take about 3 to 4 days for my system to get fully used to the French cuisine again. Their food is different in the way it is processed. The sugar and flour are visibly different (and recipes are not the same). Not saying one is better than the other, but I wouldn't want to be the one on the hook for half of the team (who have no experience to tell how they are going to react) having digestive issues.
