I love your idea with the perceptions about healthier version of traditional meals and exchanging multi-food cultures. But there exists some problems. First, TV show can only attract the minority who have much time to watch TV and who love watching TV very much, such as housewifes; but this would probably not attract people who work very busily which occupy quite large percentage of society. After work, they seems like not willing to touch digital appliances like smart phones and computers anymore, so it may not be possible for them to watch TV show after work. What they want is to relax; and when they want to get any information, they will just type some specific words, and search it on the internet. So, we can observe that TV is not popular in this group. How about uploading this show online?
Also, people who work busily actually do not have much time and energy to watch programme. So, it would be much better to make the show shorter, e.g. 15-20 minutes.
Perhaps if we change these two principles, the show may attract more people, and may spread the message of healthy and multicultural meals successfully in the future.
Last but not least, these just our suggestions, and refinement still does not finish, please feel free to comment. Thank you :)
