Indicators of Hunger

To function properly, as a body, is necessary to maintain internal balance.  This process is performed consistently as a reflection of our body is called homeostasis.  A function in the body caused by the process of homeostasis is hunger.  When there is a lack of nutrients, makes our brain us feel hungry.  When we are thirsty, you can choose to drink to meet this need, but things are a little different than hunger.  We can choose to eat a variety of foods.

Our brains have been created with different ways to choose the type of food we need.  Some of them involve basic preferences that we are born with and other ways of understanding the mechanisms of learning they prefer for certain foods.

First, we talk about taste.  This element contains the specific taste and odor components.  People come into this world “programmed” with the native inclinations and objections to certain tastes.  This is demonstrated by the fact that babies react to the sweet taste of licking the lips and the bitter taste away from the head and shows a face of disgust.  Food speculation on our best available as naturally sweet and they made the food we encourage excessive consumption.  To explain this bias, researchers believe that the sweet taste is a label for foods that are an excellent source of calories.  Similarly, the label represents a bitter taste for bitter compounds that are generally poisonous plants.

Second, there is another way to develop preferences for certain tastes: the mechanism of individual and social learning.  Such a mechanism is activated when the setting is based on the consequences of eating something with a little taste.  When we experience positive and nurturing, we have developed a form of pleasure for the taste is determined by a process called classical conditional learning.

No matter what kind of food you eat is clear that we must eat to maintain energy balance in the body.  The cells in our body to burn fuel to produce the required amount of energy needed for the functioning of the body.  The exercise to determine the muscle cells burn more fuel to meet demands of metabolism.  When you read this, the neurons in your brain also uses energy to meet metabolic needs created when electrical impulses are formed and where neurotransmitters are produced.

The main source of energy for nerve cells is glucose.  This item can be found in fruits and other foods.  Glucose can also be made by the liver from other sugars or carbohydrates.

Another important thing about the indicators of hunger is psychological.  In a sense, hunger what we feel when we feel full.  Even if we have food in the stomach and intestines, or that our store has high calories in our body, we feel quite satisfied.  When they start to decline, seems hungry.  For satiety appeared to be a special process must be performed.  Only after having eaten something, chemicals in our stomach sends a message to the brain via the vagus nerve.  Then another signal is sent when the food when the duodenum.  In this case, the CCK hormone is released into the blood when it reaches the brain is detected by the fact that specializes receptors.This is demonstrated by an experiment where the hungry animals injection of the hormone CCK.  Within seconds, he stopped eating these animals, although it was only a few bytes, that he was satisfied.

Finally, the hunger feeling that occurs when the point of homeostasis is in imbalance.  This means that the body loses its inner balance, because the calories are necessary for the proper functioning of cells is very small.  At this point, we can choose from a wide variety of foods sufficiently effective to increase the amount of glucose to balance the nervous fuel cells.
