Many will say that the best way to endorse a food product is by showing off how people really enjoy eating it. Yeah, many of the big companies will use celebrities to promote a brand because they can afford it but they also incorporate other means to attract attention.
The most sincere and effective means to catch the interest of the common people, without intimidating them too much, is to use non-celebrity everyday people that you would normally just pass by along the streets on your way to work or school. Models could be dressed up to look like the kids next door, but somehow people can distinguish the real ting from the make believe.
If you use unfamiliar characters that do not do commercials professionally, you would be more convinced to identify with the character. You will somehow feel that it is not totally forced and scripted. Besides, great food reflects naturally on the faces of people after their dining experience.
