But food sciences are, other than maximizing the utility of food, also largely focused on finding the point where food tantalizes but doesn't satisfy so that at a very base level people who eat a processed food are physiologically induced to eat more of it without ever getting enough.
"The difference between a watermelon and something processed by a large company is that, for the latter, those foods are altered in ways to make them literally irresistible. This happens when companies use a combination of salt, sugar and fat to create foods that overstimulate the taste buds — and yet are designed to never quite leave you feeling satisfied. Even though saturating foods in salt, sugar and fat fuels the obesity epidemic — and does not necessarily provide consumers with the best culinary experience — it guarantees that customers will keep coming back for more by overstimulating one's feeling of taste pleasure in exactly the right ways. Since the companies' view their foremost responsibility as being to their shareholders, that is in itself a good enough reason to continue preparing foods with excessive salt, sugar and fat."
