Summary
This episode explores why we dislike certain foods and whether tastes can be learned and changed. Experts from McGill University and BBC World Service discuss how food preferences are shaped by both genetics and learned experiences, and reveal techniques like 'masking' that can help people overcome food aversions.
Insights
- Food dislikes stem from both genetic factors (how we taste/smell) and learned behaviors, making them potentially changeable
- Negative food experiences create lasting associations that trigger avoidance behaviors, but these can be overcome with exposure
- Masking technique—pairing disliked foods with liked foods—helps people discover foods aren't inherently unpleasant, just culturally unfamiliar
- Neophobia (fear of new things) is a real psychological barrier to trying new foods, but can be addressed through gradual exposure
- Cultural and conceptual perceptions of foods (e.g., eating insects) often matter more than actual taste in determining acceptance
Trends
Growing interest in behavioral food science and taste psychology in dietary interventionsShift from viewing food preferences as fixed to understanding them as learnable and changeableIncreased focus on overcoming neophobia through exposure therapy and masking techniques in clinical nutritionRecognition that cultural food biases are learned rather than innate, enabling cross-cultural food acceptanceEducational approach to food aversion management in clinical and parental settings

Quotes
"Our food dislikes learned or genetic, hardwired in some way. Both. So there's many reasons why you can dislike a food."
Dr Dana Small•Mid-episode
"One of the really good techniques that we might use is something called masking where you dip a food that you don't like into something that you do like."
Claire Thornton-Wood•Mid-episode
"If you had eaten prawns in the past and you had become unwell from eating them, you'd have what you call a dodgy prawn. There's a good chance that you might actually associate that with eating the prawn."
