French fries, burgers, Chips and Fried food: The Western cuisine is dominated by fatty, unhealthy food offered.
Since many of these Snacks and meals are as good as at any time and anywhere, it is very hard for many people to permanently.
Morbid obesity is increasing
The result: The number of Overweight people is increasing steadily in recent years.
A dangerous Trend, because: Also from the obesity resulting in chronic diseases such as Diabetes and cardiovascular diseases to take accordingly.
But why attack so many people on a regular basis to the grease-dripping Bite? The connection between high-calorie meals and Obesity should be the most finally, be aware of.
A statement of approach has probably found a study on mice, conducted by researchers at the Max-Planck-Gesellschaft (MPG).
In their work on the portal ‘science direct’ to be published, the scientists focus primarily on the metabolic processes of the organism.
To be more precise: you wanted to find out what nerve stimulate cells eating such unhealthy foods.
Increased activity of certain neurons
The experimental gefüttern animals with a fat-containing food, and then examined.
Already after three days, in which the animals received this high fat feed, were able to determine, the researchers increased the activity of so-called Nozizeptin neurons in Parts of the brain region of the Hypothalamus.
In a subsequent Experiment, the researchers remote the mice exactly these neurons.
The result: The animals no longer überfraßen to the high-fat food. The normal feed was eaten by the mice as well as in an appropriate amount.
Excessive eating habits by activated neurons
In further experiments, the researchers genetically observed changes in mice in which the activity of the neurons by light was control.
“The activation of these brain cells has led to an excessive food intake in the animals,” explains the first author of the study, Alexander Jais,in a press release.
Because it is through this activation of the other neurons, which regulate the feeling of satiety will be inhibited. As a result, the animals take in more food than you need to saturation, actually.
Explanatory approaches for the people
Of course, it must be observed in the present study, the Experiments were only performed on mice and the test results of one-to-one are therefore not transferable to humans.
Nevertheless, could deliver according to the researchers, this “individual activity of the Nozizeptin neurons” important insights to the question of why some people take only as much food as your body requires.
“We are constantly of fat – and carbohydrate-rich foods surrounded, and our brain is wired so that we eat these high-calorie foods especially like to”, is Jais to bear in mind.
The Health risk mitigate
If this urge could be terminated after the energy-rich food, can perhaps be treated the unwanted excessive caloric intake better.
Because of the steady rise in obesity-related diseases and the associated health risk factors, better control, it is first important to understand the control of metabolism fundamentally.
