Have you ever thought of how attractive and alluring the mere sight of junk food and mouth-tempting delicacies are?
As per an interesting study, the mere sight of delicious food is sufficient to trigger ghrelin-the hunger hormone which is responsible for controlling appetite.
A link is set up on seeing or smelling delicacies and food and there is a stimulation of the appetite centre. This study is first of its kind to establish a link between the sight of food and hunger arousal.
Experts are of the opinion that the soaring advertisements of food items are responsible for fuelling the epidemic of obesity.
Axel Steiger of the Max Planck Institute of Psychiatry in Munich said, “We have proven something scientifically for the first time that people have always known: the mere sight of delicious food stimulates the appetite.
Thus, the pervasive presence of appetizing food in the media could contribute to weight increase in Western populations.”
Details of the Study:
The researches carried out an experiment to get an idea in the interaction between ghrelin and delicious food.
Healthy males were enrolled for the study.
The participants were shown the attractive images of delicious food and irresistible eatables.
The blood levels of the participants were then examined by the researchers. The levels of the metabolism hormones such as ghrelin, leptin and insulin were assessed.
The study showed that the levels of ghrelin increased considerably confirming the fact that the pictures of mouth-watering food. On seeing the pictures of food the participants started feeling hungry.
Petra Schüssler, the study authr mentioned, “The findings of our study demonstrate, for the first time, that the release of ghrelin into the blood for the regulation of food consumption is also controlled by external factors.
Our brain thereby processes these visual stimuli, and the physical processes that control our perception of appetite are triggered involuntarily.”
She further said, “This mechanism could prompt us to eat a piece of cake just two hours after breakfast.
We recommend that, where possible, individuals with weight problems should preferably avoid looking at images of appetizing food.”
