Which snack is unhealthy?

I'm curious to know, which snack among the many options available is considered unhealthy? Are we looking at high-sugar snacks like candy or chocolate bars? Perhaps it's the deep-fried, fatty options like potato chips or onion rings? Or could it be the snacks loaded with preservatives and artificial ingredients, like many convenience store options? Is there a specific reason behind why this snack is deemed unhealthy, and what potential health risks does it pose? Understanding the answer to this question can help individuals make more informed choices when it comes to their snacking habits.
