Eating is more than just the absorption of nutrients, as the saying goes, "Eating and drinking keeps body and soul together". The psyche also wants to benefit from the enjoyment of the food and not infrequently, the food intake serves as a balm for our soul. Read how food influences our soul.
So the body controls hunger and satiety
Food intake is governed by many different factors in our body. There are finely-controlled mechanisms that regulate hunger and satiety.
The focal point for the hunger and satiety is in our midbrain, the so-called hypothalamus. Here signals are received and messages are processed, for example about the degree of filling of the stomach and about the energy reserves in the body. Numerous messenger substances are involved in this regulation.
This complex regulatory system controls food intake so that we consume as much as our body needs. Saturation leads to the cessation of a meal and usually protects us from eating too much.
Satisfied and satisfied
The feeling of satiety after a meal fills us with satisfaction. If we listen to the signals of our body, we usually have a balance between energy intake and consumption and need not worry about our body weight.
However, if we constantly over-hear our hunger and satiety signals, there may be a disruption of regulation. People who often use diets often try to overcome the hunger signals and lose the natural perception of hunger.
Seduced by appetite
In addition to the information that the body sends, external stimuli in the hypothalamus are also processed. Visual impressions, such as the sight and smell of food, are conveyed to where appetite regulation takes place. The regulation of appetite plays an important role in the control of body weight. This can also cause problems:
- Often we can not tell if we are hungry or just hungry.
- If we let ourselves be seduced too often by appetite, the energy intake can quickly exceed the consumption and the bacon increases.
From the pleasures of the senses
Eating and drinking stimulate the senses. About our sensory perception, the food is something pleasant - especially of course by the sense of taste. The pleasurable melting of tenderly melting chocolate on the tongue is just one example.
The taste perception takes place predominantly on the tongue. About 7, 000 taste buds differ in the taste qualities sweet, sour, salty, bitter and umami (= tasty, the taste of glutamate).
Some taste preferences are innate
Some taste preferences and aversions are already with us from the cradle. Thus, the predilection for sweets and the aversion to salty and bitter foods is innate.
Already in the womb probably begins the taste training. Through the diet of the mother, the fetus receives taste experiences that shape his later preferences. We therefore eat some dishes with special enjoyment, others we reject.
In childhood, the learning of a specific eating behavior is added. This is decisively influenced by the family, but of course also by the food culture of a country. Whether we gleefully nibble a fresh lettuce leaf later or rather eat fries dripping with fat, seems to be anchored early.
