A study involving adults in Italy suggests that healthier eating patterns may be linked to a better sense of smell. Researchers analyzed data from 6,690 participants in the CHRIS study, assessing their ability to identify 16 different odors and comparing results with dietary habits. Greater adherence to healthy diets, including those rich in fruits and vegetables, was associated with better odor identification and lower odds of hyposmia, a reduced sense of smell. In contrast, an unhealthful plant-based diet was linked to poorer olfactory function. The study was cross-sectional, meaning it cannot establish cause and effect. Further research is needed to determine whether improving diet can help preserve the sense of smell.
