Why is junk food so good?
I think the reason junk food tastes so good is because of the amounts of sugar and fat. One would think that because healthy food is better for you it would taste better, but for some odd reason junk food is often much sore satisfying. A lot of junk food gets gross after prolonged consumption, for me, but for a snack it sometimes just seems like the perfect food to satisfy your hunger. Personally, when I go a week or so without eating sweets or junk food I dont crave it, but when I start eating it, I begin to crave it more often.
The tastes that you encounter while eating fast foods are far from natural. They are chemically enhanced to taste pleasing to our senses. This pleasure come from a perfect mixture of sodium, fat, and sugar. This mouthwatering combination that the fast food industry generates, releases certain chemicals in the brain that are gratifying and addicting. When people start eating these types of foods for a long period of time, and then stop, they get withdrawal like symptoms, and just continue to eat these unhealthy choices. People literally get addicted to fast food. Also, instinctually we crave things with fat and high calories. Back when the only thing people worried about was survival, they needed foods high in calories and fat to stay alive. Although we have evolved, our taste buds still crave these types of foods.
