The following thesis focuses on the issues regarding catering and food and its impact on health and life satisfaction of coalition soldiers during their deployment on a military operation in the Middle East area. Obviously, food is a part of our lifestyle and it is certainly an area affecting our life satisfaction, all the more affecting the life satisfaction of soldiers specifically in an armed conflict environment where they are exposed to higher stress conditions. Furthermore, life satisfaction is one of the variables influencing the work itself. And work influences our lifestyle and vice versa. It can be also said that life satisfaction influenced by the working environment also affects the health of soldiers. It turns out that work satisfaction has a very strong and lasting relationship with life satisfaction, as work is a central factor for most people, influencing their identity Firstly, it was necessary to find out and describe information from the area of catering of troops in field conditions and fighting food rations which can be provided to deployed soldiers. The authors’ fundamen-tal research question is how the catering and food in the military operational environment affects the life satisfaction and health of deployed soldiers. To obtain the data, a standardized method, Life satisfaction question-naire (authors: J. Fahrenberg, M. Myrtek, J. Schumacher and E. Brähler, 2001), was used. Food and catering play a very high role in our lifestyle, affects our health and furthermore, the quality of life in any situation. In life satisfaction, Danish soldiers have higher values, followed by American soldiers, and British men are the least satisfied during the foreign operation. The reasons for differences and their clarification corespondes with the last published “Happines Index” which is investigated annually by the United Nations agency.
