Scented path to healthy eating: study reveals the influence of sweet odors on food preferences WUR odor eating habits publichealth scents foodpreferences
By Dr. Liji Thomas, MDJun 19 2023Reviewed by Lily Ramsey, LLM With growing rates of obesity and non-communicable diseases worldwide, much concern is centered on encouraging people to choose healthy foods as part of a balanced and adequate diet.
Energy-dense foods are always more available and accessible than healthy foods that have reduced levels of salt, sugar, and fat. Nonetheless, sweet snacks always get more visual attention and are chosen more frequently, irrespective of previous odor exposures. What did the study show? Surprisingly, odor exposure had no obvious effect on the choice of healthy or unhealthy foods. Overall, healthy foods tended to be chosen more often, regardless of prior odor exposure.
As expected, visual fixation was associated with food choices. People who fixed on a food product for a greater duration were more than 1.6 times more likely to choose it, while those who looked at it more often were 53% more likely to choose it.
