Why do we love junk food?
Lexile

You asked us a question. "Why do we love junk food?"
 
A lot of money goes into making junk food. A lot of strategy goes into making junk good too. Effort also is a big part of making junk food.
 
The goal is to make it cheap. It needs to be easy. And even though it has little to no nutritional value it keeps you wanting more.
 
It is often high in things like salt and sugar. It also has a lot of fat. They start pleasure centers in our brains. Those make us feel oh-so-yummy-good. And they make us want to keep eating.
 
See, our brains are pretty big. They need 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. That is when it comes to making us really want their products.
 
Like the melt-in-your-mouth quality that tricks us. We think the calories have magically floated away.
 
Or boosting flavor just short of what is called, "sensory specific satiety."  It is flavor that is really big. It overwhelms your brain. And you end up not wanting anymore.
 
We know that it is not good for us. Eating junk food it is linked with many health problems. Some of those are obesity and diabetes. Heart disease and even cancer are also linked to junk food. But even with those problems junk food can be really hard to resist.
 
Food for thought, for sure.

    This is interesting. Until now, I've always wondered the reason for liking unhealthy, sugary things. What is it about healthy foods that are so unappealing to our brains?

      That is a good question... What if we mixed the two foods so we gain good and bad qualities at the same time, with the satisfaction of junk food!

    It takes a long time to make junk food because they have to make it taste good so you always want more.

    Junk food takes a lot of time to make because it takes a lot of effort into making candy and junk food and it takes time but the idea is to make it cheaper than it should be.

    One trick junk food makers use is the melt away in your mouth trick which makes people think that the calories have just melted away. One health problem that junk food can cause is cancer, another one is heart disease.
