Any addictive food usually has a main 3 ingredients fat, sugar, and salt (F.S.S). Any example of addictive food has these three ingredients F.S.S. For example Oreos are made up of all of those ingredients so you won't stop eating. Some foods are not even made up of real food, for example in the video it shows the at you can make a cheese flavor enhancer without the cheese! You just have to mix F.S.S and some proteins to make it. The makers of this product use fake cheese so that they don't have to pay so much for real cheese. The food scientist’s make it so that there is a chemical reaction that comes from your tongue to replicate something that it is not.When we eat food, a “reward system” in our brain lets out chemicals such as the neurotransmitter dopamine. when we eat an addictive food it releases this chemical. This chemical gives us pleasure. so when we eat more and more of the is food our dopamine levels go down. This will make you think that is bad for food companys, no it is quite the opposite. you will crave the taste that we had when our dopamine levels were 100%.
