Opiod

Homeostasis maintain processes in our body. It means body create its own balance to survive. If homeostasis is in danger, it send a signal to the “control center”. In homeostatic the “control center” is the brain. The “control center” take a proper response to that signal and send signal back to the effector (muscle, organs). After that the changes occurs to correct the balance, with positive or negative effect. This also works when people are hungry. People feel hungry because brain send signal to the stomach. It’s not like our stomach is hungry, it feels hungry because brain send that king of signal. People eat when they are hungry and stop when they are full. But our brain can’t send the signal ”I’m full” back because of palatable food(food including sugar, fat and salt).This is happening during consuming fast food. Instead of sending signal “I’m full” back to stomach, food activate the region of brain that is called reward center. The reward center is responsible to feel feelings like happiness, excitement. Because of that people eat more and more to feel that “happiness”. After when signal was sent to the “reward center” it’s released “opiod”. Opiod is very similar to the drug called opium. Opium is used to produce heroin and other drugs. Opium makes our body feel great and we want to eat more and more to feel that pleasure. That’s why food containing a lot of sugar, fat and salt will make people come back to feel that happiness.
