Eating a lot of fat reduces the sense of smell

(Scientists from the University of Florida) claim that eating a high-fat meal can reduce the sense of smell.

They discovered an inexplicable link between unhealthy meals and 'big changes in the structure and function of the olfactory system, helping us smell'.

The team found that the link between obesity and body functions does not always go together.

For the first time, they discovered a 'sustainable link' between unhealthy diets and a decline in olfactory ability, 'opening up many prospects for obesity research' , said Dr. Nicolas Thiebaud. .

Mr. Thiebaud and Professor Debra Ann Fadool conducted the study. Their study was published in the Journal of Neuroscience.

The researchers also said that because the sense of smell is used to guide food choices, if its ability or strength is hampered by unhealthy foods, it can lead to a vicious cycle. , gradually forming 'poor eating behavior'.

People have fed rats with fat foods for 6 months, while also teaching them to recognize flavors by rewarding them.

Mice with a high-fat diet were slower to learn than normal rats. They cannot quickly adapt to new flavors.

'What's more, when mice fed high-fat diets were replaced with a controlled diet, during that time, even when they returned to their weight and content. chemically in the blood as usual, but still has reduced olfactory ability , "Ms. Fadool said.

'These mice have only 50% of neurons involved in coding the odor signal'.

The team is also working to see if a high-sugar diet can have such a negative impact on the sense of smell.
