Eat for Every Taste

I have a theory that's completely unproven. You tell me if you think there's something to it. My theory is that the more tastebuds a meal touches, the more likely you'll be satisfied with it. Creating a well-balanced meal might be more than adding up macros. It might mean striving for variety in both taste and texture: sweet, salty, sour, and savory in every meal.  Flavors balance each other and add to the robustness of the meal. 

Kind of like, "The quick brown fox jumps over the lazy dog" approach to diet (the whole alphabet in one sentence). Why not?

What meal can you think of that uses maximum tastes and textures?
