Why eating dessert is better than sweet snacks

I recently dove into an interesting book called Glucose Revolution, and one particular insight really caught my attention: it's better to eat dessert rather than indulging in sweet snacks, but why? 

🧁Surely eating sweet food as a snack or after a meal wouldn't make much of a difference to our health, right?🍭 

Well, we're mistaken! I've summarised some key points from the book that explain why this is the case, and I think you'll find it as intriguing as I did!
