Why Do Some People Prefer ‘Sweet’ Over ‘Salty’ Foods?

Imagine your brain is like a detective, always trying to figure out what it needs. If you eat something sweet, like candy, the detective says, 'I feel happy!' But if you eat something salty, like chips, the detective might say, 'I need more water.' That’s why some people like sweet food better, their brain feels extra happy when they eat it.
