NEW YORK (Reuters Health) - The intestines, not the stomach, are responsible for this feeling, opening the way to fight obesity, according to a new study.
Researchers from the United States found in a new study that it is the intestine, not the stomach, that sends a signal of feeling full to the brain, and instructed the body to stop eating.
The researchers said in their study published in the journal "Cell" on cell research that there are nerves in the intestines record the intestinal diastole and send a nerve signal to the brain, adding that the results could explain the reasons for the success of stomach reduction in weight reduction.
The study indicates that the human body measures the quantity and quality of food, and accurately regulates the volume of food we eat, and the time when you should stop eating.
Although food is important to human life, "we do not yet understand" exactly how the body stops hunger, said study author Zachary Knyat of the University of California.
The researchers pointed out that many of the nerve fibers in humans participate in the transmission of a sense of satiety, and these signals are transmitted through a central cerebral nerve known as the vagus nerve to the brain.
Scientists have developed through this study what can be described as a map of nerves in the stomach and intestines, relying on the biological and anatomical characteristics of the nerves, and showed them through experiments on mice that the nerve fibers in the intestines control food, where stimulation of these nerves in mice Hungry to stop eating.
Although the nerves that record the diastole of the stomach inhibit the desire to eat, this effect was not as strong as the nerves that measure the diastole of the intestine, and this says lead researcher Ling Bai "This was somewhat unexpected, because according to the belief that decades ago, It is the stomach that records the volume of food, while the hormone receptors in the intestines measure the energy content of this food.
The research raises the question of the extent to which receptors can be directed to contribute to the fight against obesity, while the researchers believe that the study may provide in the future an explanation for the reasons behind the success of stomach reduction in obese people "but this is only a prediction must be validated," according to nicknames .
Obesity damage
Obesity raises the risk of many diseases, such as diabetes, high blood pressure, heart failure, heart attacks, back pain and arthritis, said German nutrition expert Annette Saberski.
Other illnesses include shortness of breath, snoring, sleep apnea, severe sweating, and depression.
To avoid these risks, Sabersky advises to address obesity through a healthy diet low in sugars and fats, while avoiding what is known as "emotional eating", ie eating in the event of sadness or stress. A: No
Along with diet modification, exercise should also be maintained at a rate of 150 minutes per week, especially endurance sports such as walking and swimming, with muscle-strengthening exercises as well.
