This is a real possibility. I might also add that by connecting to community food markets, you might have an additional venue whereby to sell some of your inventions and promote your concept to the wider community. Kudos!
I think you are bang on here! Most of the Ads relate to 'lifestyle' so my thoughts would be to create a sexy lifestyle that speaks to mainstream culture, but hits up on the 'you are what you eat' concept where beautiful means fresh. Are there any fresh food ambassadors? People to emulate that are REAL people that eat REAL food?
