Consumption of High-fat Foods May Lead to Loss of Sense of Smell

A new study has established an association between high-fat diet and its effects on the structural and functional changes occurring in the olfactory system of our bodies. The research has been undertaken by neuroscientists at the Florida State University to understand the effect of diet on human senses and functions that are not generally considered when the impact of obesity on our body is studied. 

This research is the first of its kind that shows a link between bad dietary choices and loss of smell. The research presents many possibilities for research on obesity and its effects on human senses. 

For the study, mice were fed diet with high-fat contents and were taught to correlate between a particular smell and a reward (water) for accurately judging the smell. 

The researchers found that the mice that were fed high-fat diet were comparatively slower in studying the association between the particular odor and the reward. In order to monitor the affect on sense of smell of the high-fat diet, the researchers introduced a new smell. The mice that were fed high-fat diet were not able to adapt rapidly to the change in smell. This clearly indicates a decline in the smelling capacity of the rodent. 

Researchers further plan to investigate whether the impact of high-sugar diet on human senses has the similar detrimental effects as has high-fat diet.
