Good food is defined as foods that taste sweet, savory, fatty and salty. Some people sometimes claim to have a 'sweet tooth' or 'salt tooth' because it always wants to eat good food.
The desire of people to eat certain foods are delicious-called experts like cravings. This is something extraordinary sensation and makes people think how to get the food.
"It's important to remember that people eat not only because of hunger but also because of passion," says Professor Andrew Hill, head of academic unit of psychiatry and behavioral sciences at Leeds University.
Experts believe the emergence of a strong desire to eat the foods you want or craving, associated with chemicals in the brain and the needs of the body.
For example if you wanted to eat salmon because the body requires omega-3 fatty medium. When you want to eat tuna because the body is needed salt, when I want to eat meat because the body is needed protein.
The experts see a strong desire to eat good food is closely associated with behavioral cravings. When the cravings, the body sometimes does not want to know whether the stomach is full or not. So many people want to continue eating fooled again.
This is related to the release of certain hormones from the body especially stress hormones. Stress always arise in human life at any time and any age.
Crave explanation is more complex than just a hungry stomach. When an empty stomach, your body releases the hormone ghrelin that will communicate with the brain center hipotamulus. That way people came to know that it was time to eat.
If the hunger that is answered with a meal, then as a form of satisfaction with body releases the hormone leptin produced by fat cells and will be produced by the pancreas to release insulin.
Conversely when cravings then there are some chemicals in the brain that reacts. First is the release of dopamine, a chemical in the brain that is associated with concentration. Dopamine is going off when seeing or experiencing something new.
Dopamine is then going to work with other chemicals that opioids that provide a sense of pleasure or enjoyment. Cooperation of these two brain makes people want happiness and do it again.
As a result of two chemical reactions in the body, people will continue to look for good food and ignore the problems of nutrition and health food.
"People are programmed to enjoy fatty foods and sugar, and then the brain will tell us to look for food," said psychologist Dr Leigh Gibson of Roehampton University.
But the emergence of the desire to eat well, according to experts also strongly influenced also by the mental conditions associated with stress or unhappiness.
When under stress for example, people will look for sweet or fatty foods. This is because when the body will produce the stress hormone cortisol. If this hormone is out he will increase blood sugar levels, because more energy is needed.
That is why when under stress people tend to look for foods high in sugar like cakes and sweets.
But experts warn the desire for a good meal should be balanced with lots of movement and control of ourselves so as not excessive, so the food does not add up to the bad fats in the body.
