Food Junkies Podcast

In this episode, Dr. Vera Tarman and Clarissa Kennedy welcome Dr. Barry C. Smith, a former food industry consultant and an expert in sensory perception, to discuss his transition from working with ultra-processed foods to advocating for healthier eating alternatives. Dr. Smith shares his journey from studying philosophy and sensory perception to becoming involved in the food industry, where he provided insights into how we perceive taste and flavor. He reveals the complexities of multi-sensory perception and how the food industry uses this knowledge to enhance the desirability of processed foods.

Dr. Smith delves into the interplay between our senses—taste, touch, smell, and even sound—and how these senses influence our eating experiences. He explains how texture and aroma can trick our brains into perceiving food as sweeter or more flavorful than it is, often leading to overconsumption. Dr. Smith also discusses his experiment of cutting out ultra-processed foods and its profound impact on his well-being, including reduced cravings and improved mood.

The conversation touches on the ethics of the food industry, the challenges of regulating ultra-processed foods, and the importance of informed choices for consumers. Dr. Smith offers practical tips on enhancing the sensory experience of whole foods, making them more enjoyable and satisfying.
