Basically, junk food is a category of food high in calories, salt, and processed sugar and is often deep-fried. Salted and sugary snacks like chips, candy, sweets, desserts, and fast/street food like burgers, Pani puri, samosa, and pizza (depending on nutrients and how it is prepared) are mostly the food choices that one has today’s life.

This kind of food seems cravingly delicious, but you are not doing any favor to your body by eating those low nutritional unhealthy food. Instead, you are doing the opposite. It is harmful because of the adverse effects it has on your well-being.
Research says, watching ads about processed foods encourages people to eat more of them. It actually activates the reward system in the brain when one eats it on a daily basis, in the same way as addictive drugs (cocaine & alcohol). So, the more you eat, the worse your body gets, but you feel satisfied like any other drug.
Manufacturers consider two factors while preparing these kinds of foods; the first is “sensation” while eating, which includes its smell, taste (sweet, salty, spicy, etc.), and crunchiness. The second factor is the nutrients in it, which are very few, but they add the perfect blend of fats, proteins, and carbohydrates that excites our brain and makes us want to eat more often. (2)
