Researchers from Inserm (National Institute for Health and Medical Research) have discovered a link between obesity and a second brain responsible for regulating digestive functions, called the “enteric nervous system” (ENS).
The work, published in the scientific journal The Journal of Physiology, show how certain nutrients have the ability to disrupt the functioning of this ENS. This “mini brain”, similar to “a network of neurons, located in the digestive tract [est chargé de contrôler] digestive functions “, explains neurobiologist Raphaël Moriez of Inserm, interviewed by AFP. This dysfunction of the enteric nervous system could contribute to the development ofobesity. >> More information on obesity and overweight in our special report
The dangers of eating too rich
In the eyes of scientists, food rich in fat and sugar, such as sodas and pizzas. The researchers observed, by experimenting with mice, that a diet that was too fatty and sugary could decrease the loss of neurons, usually seen over time. Problem, when these neurons are present in too large a quantity, the stomach empties too quickly and reduces the signals of satiety. In other words, by accelerating gastric emptying and by increasing the desire to eat, a diet too much calories would promote obesity. >> To read also: How to start the Weight watchers method
“We believe that by preventing the natural evolution of the enteric nervous system over time, the diet high in fat and sugar would prevent the digestive tract from adapting to a corresponding diet in adulthood and maintain its corresponding youthful phenotype. at a period of life when food intake is maximum “, specifies one of the researchers. And to conclude: “In the long term, the prevention of digestive neurodegenerative pathologies, even of the central nervous system, could be modified by nutritional approaches”. One more reason to favor a balanced diet. >> To read also: 5 deviations that do not (not grow too much)
