A recent study showed that food is more satisfying if it is described as "tasty" rather than "healthy." This means your family will be less hungry overall if you choose the right words when describing your meals.
As CEO of Whole Foods Market, I believe that great organizations have great purposes. The highest ideals humans aspire to should be the same ideals that our organizations have as their highest purposes.
While it's true that taste is subjective, I've never heard a convincing argument that it's better to dislike a food than to like it. It is certainly more fun to like things, and it is often far more convenient.
