Stomach MRI images combined with functional fMRI of the brain activity have provided scientists new insight into how the brain listens to the stomach during eating. Research from Wageningen University in the Netherlands shows - for the first time - real time data of the brain, the stomach, and people's feelings of satiety measured simultaneously during a meal, in a study to be reported this week at the annual meeting of the Society for the Study of Ingestive Behavior, held in Porto, Portugal. The researchers collected data from 19 participants during two separate sessions with different consumption procedures and found that a simple change like drinking more water can alter messages from the stomach interpreted as fullness by the brain. This new research approach can be used to investigate the interplay between satiety feelings, volume of the stomach and activity in the brain.

In the experiment, participants drank a milk-shake on an empty , which was followed by a small (50 mL) or large glass of (350 mL). MRI images were used to see how the different amounts of water affected stretching of the stomach: the large glass of water doubled the stomach content compared to the small glass. Together with this larger volume subjects reported to have less hunger and felt fuller.

This novel approach - combining information obtained simultaneously from MRI images of the stomach, feelings reported by the subjects, and scans - can offer new insights which would otherwise have been unknown, for example that activation in a brain area called the mid-temporal gyrus seems is in some way influenced by the increased water load in this experiment. The Wageningen University scientists developed the combined MRI method as part of the European Nudge-it research project, which seeks to discover simple changes that promote healthier eating. They will use it to search for a brain signature that leads people to decide to stop eating, to determine how strategies like water with a meal can be effective at feeling fuller sooner.

"Combining these types of measurements is difficult, because MRI scanners are usually set-up to perform only one type of scan. We've been able to very quickly switch the scanner from one functionality to another to do this type of research" says Guido Camps, lead author of the study. "In conclusion, we've found that simply adding water increases stomach distension, curbs appetite in the short term and increases regional ."

What can we conclude from this? Coke, Pepsi, Cool-Aid, Gatorade, etc.... , all of which full of artificial chemicals that only "mimic" natural ones are toxic poisons to the Human Body because not only do they compete with natural organic materials for lock-and-key receptor stimulus-response "fitness" that are pro-Human life during operations of the digestive-metabolic System, but they also accumulate throughout the Human Body to trigger certain "unnatural processes" that ultimately give rise to the many diseases, illnesses, and ailments that plague Human Beings in industrialized societies such as Western Nations where Cancer, Auto-Immune Allergies, Stroke, Heart Disease, Diabetes, and a host of other curses as opposed to agricultural societies whose organic Foodstuffs are still greatly very much connected to the Fundamentals of the Planet's natural Ecological Bio-Mass Life-Support Systems.

It's a great research! It only confirms the correspondence between how God-engineered Nature is organized to normally sustain Biological Life: Body-water composition estimated at 75-80% and how Water is the basic fundamental Source-and-Keeper of Life! It is in the same way that Earth-core is Iron molten magma and our red-blood is also structured around Iron-based hemoglobin without which chronic anemia sets-in. Likewise, as Nitrogen, Carbon, Hydrogen, and Oxygen are the four basic elements perfused throughout our Organic Foodstuffs, then it follows that -- not to totally deride the benefits of Technological Industrialization but rather aiming for its improvement -- these four elements will also permeate all materials necessary for supporting-and-sustaining Human Life, such as Proteins, Vitamins, Minerals, Enzymes, and Phospho-Lipids.
