But suppose a person is not hungry and still he sense any food, will it metabolize food substance present in body related to tasted food or not?
Furthur, will this effect be more (i.e.more secretions) in case smaller/dissolved molecules of any food is tasted insted of raw food?
Kumar, your body is basically a big chemistry laboratory, with lots of chemical reactions going on every minute of every day. That's what keeps you alive--those chemical reactions going on in your body.
And one of the chemical reactions that takes place is the one that gives your body energy to walk around. Your body does this by digesting food. The food gets digested, the proteins and carbohydrates get processed into energy for your blood and your muscles to use to keep you alive.
Now, your body never shuts down from doing this. If your body ever stopped doing this, you would be what we call "dead".
So since your body never shuts down from doing this, it always needs a reliable fuel source, 24/7. We call this fuel source "food". If no food gets put into your body, your body doesn't simply shut down its chemical reactions and stop trying to digest food--no, what your body does is start using its own resources to get some fuel for its chemical reactions. The first place your body looks for some fuel is in its own fat. If you don't put "food" into your body, it will start burning its own fat to get fuel for its chemical reactions.
After it has used up all the fat, it will start burning its own muscle tissue to get fuel to make its chemical reactions go. It won't stop doing this. If it stops doing this, you become what we call "dead".
Now--none of this has anything to do with whether the body sees, or smells, or tastes "food". This process all keeps on going whether or not the body sees, or smells, or tastes "food". If the body isn't given "food" to use for fuel, it will start using its own fat and muscles for fuel.
It also doesn't have anything to do with whether the person is "hungry" or not--the body keeps right on with the digestive process. Your body keeps trying to digest food and send energy to itself 24/7. Always. Constantly. It never stops. It doesn't care whether you're "hungry" or not, it doesn't care whether you see or smell or taste some "food"--your body is still always working away at "digestion" and making energy to keep itself going.
Is this making sense to you? Your body is a big chemical factory that started the moment you were conceived in your mother's womb, and it won't stop until the day you die. It doesn't care whether it sees or smells or tastes "food", it doesn't care whether you're "hungry" or not--it's still going to keep right on doing those chemical processes that give it energy.
What is your point here?
Your brain cannot control the process of digestion. You cannot tell your body, "Stop trying to find and digest food." It's automatic, your body does it all by itself, it's not up to you.
Yes, the amount of digestive secretions put out by your body vary in relation to what kind of food you send down there--if you send down something really greasy, your gall bladder is going to send out more bile to help digest that fat, whereas if you eat some fat-free crackers, your gall bladder doesn't have to put out so much bile.
But what's your point?
Pls read the following links:-
Three of those links do not work; they are giving me a "Cannot Find Web Page".
And your Google search link just searches for the string "Ce...le Search" which makes no sense.
