New research shows a high-fat diet damages the sense of smell and may have an impact on other human functions, Florida State University announced Monday.

The National Institutes of Health funded the study published in the Journal of Neuroscience. It showed that the high fat diet caused a loss of olfactory sensory neurons. It also reduced olfactory discrimination and disrupted odor-reversal learning.

Scientists were planning on conducting other studies to determine if exercise could slow down a high-fat diet's impact on smell.
