While the sense of smell may not be the first thing that people long to improve on their bodies, recent studies have shown that there is a special hormone that may improve a person’s ability to sniff out certain foods. The hormone is called ghrelin, and it is not necessarily a recent discovery in the medical world. For a long time now, researchers have known that there was a correlation between ghrelin and hunger. This hormone has also been said to be linked to food storage. Now, however, researchers have found that it may also play a part in the way people smell food around them. Here is a synopsis of some of the research scientists have gone through over the years.
The study was conducted by a group of scientists at the University of Cincinnati. Their research showed that ghrelin can increase a person’s ability to smell certain foods and know what they are. The study also suggested that the hormone may be a factor in the body’s ability to link food smells to the regulation of body weight and metabolism. This study was published in the April 13th issue of “Neuroscience,” and it has sparked some conversations in the medical world.
Researchers tested humans and rats to make a determination about the link between ghrelin and food smells. Throughout the study, researchers found that increased levels of ghrelin in the body helped participants pick up on certain food smells and subsequently determine what the foods were. This research can help members of the scientific community better understand the human body and the way it works in certain situations.
Some studies separate from this one have also shown that people can smell better when they get hungrier. It may be easy to assume that the desire that spawns from hunger helps people target smells better, but the truth is that ghrelin may play a big role in that. Ghrelin is, after all, a hunger inducing hormone, so high levels of ghrelin may indirectly lead to an enhanced sense of smell. This is breakthrough research that puts a whole new perspective on the way scientists see the human sense of smell.
In the future, researchers plan to look into just how ghrelin affects the sense of smell on a molecular level. The studies related to that discovery will have to come at a later date, but for now it is nice to see that researchers are gaining a better understanding of the human mind and nose. Developments like this may actually lead to medical advances in the future, but the studies are in their infancy at this time. More research will be coming in the years to come.
