If nothing else: It's certainly useful that mother's milk tastes good to babies. Imagine what an evolutionary disadvantage it would be if it tasted bitter.

- arde 3y agoTo make it explicit for those who haven't tasted it, mother's milk tastes distinctly sweet (literally), in a way cow milk does not. So yeah, there's a probable purpose for sweet receptors. An interesting question is whether seeking sweet foods in modern adult life, which would probably not have been available in our evolution, guides us to a healthy diet.
