Here's the Skinny on Soup
With news that American health remains in general decline and more than one-third of adults are obese, consider this a public service announcement: Soup is the secret weapon against fat. Scientists have confirmed that soup keeps you fuller longer than other food.
After you eat a meal, the pyloric sphincter valve at the bottom of your stomach holds food back so that the digestive juices can get to work.
Water, however, passes straight through the sphincter to your intestines, so drinking water does not contribute to “filling you up”.
When you eat the same meal as a soup, the whole mixture remains in the stomach, because the water and food are blended together. The scientists’ scans confirm that the stomach stays fuller for longer, staving off those hunger pangs.
