New scientific data question the long -term benefit of artificial sweeteners to control appetite and reduce calories. A study conducted by an international group of scientists and published by Science Alert has found that the use of superalose - one of the most common sugar substitutes - can lead to an increased feeling of hunger.
The study was attended by 75 adults who drank drinks with different types of sweeteners in the format of cross -experiment. When the participants consumed a drink with sucora, they had increased blood circulation in the hypothalamus - the area of the brain responsible for the regulation of appetite. This indicates the activation of food motivation, despite the absence of calories.
In contrast, after drinking a sucrose drink - ordinary table sugar - blood flow to the hypothalamus decreased, which coincided with a decrease in the feeling of hunger. The level of glucose in the blood increased sharply, activating the physiological signals of saturation. Two hours later, the participants who consumed sucrose reported much less hunger than those who drank the supersrillosis.
These results correspond to previous studies, including animals that have also demonstrated similar effects. Scientists suggest that the problem is a "rupture" between what the brain expects after a feeling of sweet taste, and what really happens to the body. Supralose, which is about 600 times sweeter than ordinary sugar, does not bear calorie value and does not cause a typical hormonal response of the body - in particular, does not contribute to the release of insulin or glucagogon -like peptide, which usually signal saturation.
Such mismatch can lead to the fact that the brain does not "believe" in the signals sent, causing increased appetite and even changes in neural ligaments. Scientists have also found that these changes have been more pronounced in overweight or obesity, which can have important consequences for weight loss strategies.
Additional studies are currently underway, in particular, to better understand how such sugar substitutes affect the brain of children and adolescents. The results obtained can have a significant impact on the recommendations for the use of artificial sweeteners, especially in food -oriented foods.
