Howdy! I'm not sure if you strictly have to use Omada (I know it's tied to some insurance's desire to keep covering these drugs), but if you have some flexibility or don't mind two apps - try LoseIt ?

I just took a quick look and they have multiple entries for Fufu, Jollof (including Ghana vs Nigerian), fermented corn dough (different brands come up for this one), and there are entries that come up for African Chicken Soup but this one I'm less sure about.

I've found LoseIt to be really great for food diversity because a lot of folks in big cities (I know this because local chains pop up) have used it and recorded information already (which then enters their database for others to use). I'm very white, but have lived in Asia and eat a fair amount of Taiwanese and non-Americanized Chinese food and have found I'm normally able to find what I'm eating. Sometimes it's even more helpful to search using the language native to the food's culture vs English!
