People hide 'fat detectors' in the nose

We use many methods, from counting calories, starch to analyzing indicators, to find out which foods are best. However, scientists discovered, a diet's best friend can be right in their nose.

Researchers from Monell Center (Philadelphia, USA) discovered that we can use the sense of smell to detect fat in foods. Because the smell is almost always detected before the team, the team believes that their work identified one of the first sensory properties that signaled whether a certain food contained fat.

As the nutrient that contains the most calories, fat has become a desirable energy source in most human evolution. Therefore, the ability to detect fat sources in food is believed to be an advantage for humans.

According to the journal PLOS ONE, scientists know, people use sensory signs to detect substance , but they are not sure exactly which senses have brought that ability. The team at the Monell Center said that the detection of fat through the use of the olfactory bulb would be beneficial in identifying remote food sources.

Although a previous study has identified, people can use scent to detect the amount of pure fat in the form of fatty acids, but it has not yet confirmed the ability to "sniff" fat saying they are in food. .

To find the answer to this skepticism, Monell scientists have conducted three experiments to see if humans can "smell" the amount of fat in milk. The results showed that volunteers were able to use the sense of smell to distinguish different fat content in this food.

That possibility has not changed in the people of both countries participating in the trial, in which the Dutch consume more milk daily than Americans. The team did not see any link between the weight of volunteers and the ability to "smell" fat.

The team concluded that humans have fat "detectors" right in the nose. This discovery can help people learn how to adjust their diet and reduce fat intake in the future.
