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.
