Thanks. That's very helpful.
For Dr. Warshawski on Zoom, how do the nature of marketing and the profit margins or the business of sweet, salty and fatty foods prey on our most prevalent biases towards those foods? I'm asking you a bit of an anthropological question, I suppose, because as humans we have an evolutionary bias towards those foods. How do those big companies, such as chips, chocolate and sweet beverage companies, prey on that?
