People with high BMI are sensitive to the smell of food, and the olfactory sense is too sharp to eat too much?

BMI (body mass index)People who are high are sensitive to the smell of food compared to people with low BMI and insensitive to smells other than foodUniversity of PortsmouthIt became clear by research of. BMI is an index obtained by dividing body weight (kg) by the square of height (m), with over 25 being overweight and over 30 being obese.

Fasting · fullOlfactionIt is the first time that this research examined the relationship between BMI and BMI.

Portsmouth University Psychology DepartmentLorenzo StaffordDr. initially started research to find out whether human smell is affected by whether it is hungry or satiety. Thesis isChemical SensesIt is published in the magazine.

It seems likely that you will be more sensitive to the smell of food so that you can get the food smell from afar and be able to take it to your meal, but 64 men and women aged 8 to 49 years old From the results of the tests conducted on the subject, it was unexpectedly apparent that the olfactory sense of people was sharp towards smells other than food when on an empty stomach, and it was more sensitive to food smells became.

Although the reason for this has not been elucidated yet, Dr. Stafford says that it can be thought of as a mechanism for detecting and refusing unnecessary food in order to maintain a proper energy balance.

64 male and female subjects underwent a test to sniff food-related smells and foods, respectively, on an empty stomach and full stomach. As a sample of the smell of food, a discrimination test (sniffing the odor of the food from the odorless sample) using the herb-based natural fragrance used in the food industry is carried out, and as a sample of a smell other than foodButanolUsingThresholdWe conducted a test (measuring the minimum odor concentration that can be perceived).


And further analysis of the findings revealed that people with high BMI are sensitive to the smell of food compared to those with low BMI and insensitive to smells other than food. Although obesity people 's olfactory sense is weak, it seems to have been suggested in various studies carried out so far, but as for the general smell, even if this applies, even if this is true for the smell of food obese people On the other hand, the sharp tendency is revealed for the first time this time.

Dr. Stafford says that a "fattening" person could also have an influence on the food intake of the olfactory acuity associated with food. "The portion that processes olfactory information in the brain (olfactory cortex)Feeding centerIt has been clear from a long time that it is connected with. However, the extent to which the olfactory cortex controls food intake has not yet been elucidated. I hope that this discovery will inspire further research in this field and will lead to people's weight management and usefulness at medical scene. "
