Dietary fiber suppresses cravings and makes you slim
Everyone knows cravings. The unpredictable appetite seizures can be harmless, but they can also have pathological causes. British researchers have now shown in a study how fiber can suppress cravings and ultimately make you slim.
Food cravings can have many causes
Everybody knows about food cravings, in which you get an overwhelming appetite for something sweet or cravings for chips. This can be caused by frustration, stress, hormonal disorders such as an underactive thyroid or metabolic diseases such as diabetes. Eating disorders can also be considered, and unrestrained appetite can also indicate excessive colonization with intestinal fungi (Candida albicans). The tips against cravings are as numerous as the possible causes. Now there is new advice: British researchers showed in an experiment that a breakdown product, which is produced during the digestion of fiber, acts as a natural appetite suppressant.
Healthy diet with lots of fiber
A high-fiber diet helps stimulate digestion and prevent constipation. The healthy fibers can even protect against colon cancer and lower the risk of a heart attack. Fiber is not only healthy, it also reduces hunger and thus contributes to a normal body weight. This effect is based on metabolic products that are released when indigestible carbohydrates are broken down. The increased production of propionate reduces the daily calorie intake. Because this substance dampens the activity of brain regions that are normally activated when appetite is stimulated, as British scientists have now shown.
Normalize disturbed eating behavior
As researchers from Imperial College London and the University of Glasgow report in the American Journal of Clinical Nutrition, a dietary supplement that increases the release of propionate in the intestine could help normalize disordered eating behavior. According to the information provided, the study participants received a milkshake that contained either inulin propionate ester or inulin. The activity of specific brain regions was later analyzed using functional magnetic resonance imaging. During these brain scans, subjects were shown high or low calorie foods.
It turned out that the participants reacted less strongly to the seductive images after the consumption of propionate than under pure influence of inulin. In particular, in parts of the brain's reward center, the scientists found comparatively low activity - in regions that had previously been linked to food cravings in earlier studies. In a further step, the test subjects were offered a pasta dish with which they could eat their fill. After all, under the influence of propionate, they left around ten percent more pasta.
Effective nutritional supplement
For the researchers, this is a clear indication that the dietary supplement is an effective appetite suppressant. Study author Professor Gary Frost, who led the investigation with Dr Tony Goldstone, said in a statement from Imperial College London: “Our results so far have shown that people who consumed this ingredient gained less weight - but we didn't know why. This study provides the missing particle in the puzzle. It shows that this supplement can reduce brain area activities that are related to food reward while reducing the amount of food they eat. "Co-author Claire Byrne said," If we consider inulin propionate esters Using nutritional supplements could reduce appetite for high-calorie foods. ”The same effect could theoretically also be achieved by eating a high-fiber diet without the artificial addition of propionate, but in order to produce a comparable amount of the appetite-suppressing breakdown product in the intestine, one would need around 60 grams a day consume of it. According to Frost, this amount would hardly be reasonable. (ad)
