You asked us, "Why do we love junk food?"
A lot of money, strategy and effort go into designing junk food.
The goal is to make it cheap, convenient, and -- despite having little to no nutritional value -- to keep you wanting more.
It's typically high in things like salt, sugar and fat, which trigger pleasure centers in our brains, making us feel oh-so-yummy-good and encouraging us to keep eating.
See, our brains are relatively big and require a lot of energy to do their thing. So we evolved to love high-energy food.
Beyond the super high calorie count, junk food makers have a million tricks up their sleeves when it comes to making their products irresistible.
Like the melt-in-your-mouth quality that tricks us into thinking the calories have magically floated away.
Or boosting flavor just short of what's called, "sensory specific satiety" -- flavor that's so big, it overwhelms your brain and you end up not wanting anymore.
So despite knowing it's not good for us -- eating it is linked with things like obesity, diabetes, heart disease and even cancer -- junk food can be really hard to resist.
Food for thought, for sure.
