Why do we want cookies or cake after a Meal? Is there something physiological that makes that happen? Max Planke, from the Florida Institute for Neuroscience, decided to find out. It was already known that there is a group of nerve cells, called the POMC neurons, that make us feel full after a meal. But what Planke discovered was that these same nerve cells are responsible for sugar cravings. After eating the sugar treat there is a release of opiate endorphins giving a satisfying feeling. When studying this process in mice it was discovered that the endorphin release happens just by anticipating the sugary treat! Scientists think understanding this process could help with obesity.
So, this explains what and why for dessert cravings but is there science in the dessert itself? Of course, there is because cooking is chemistry! Let’s bite into this by analyzing chocolate cake. To create the perfect moist soft chocolate cake the protein gluten in flour must be processed perfectly. When mixed with water the gluten is activating creating a web like structure that traps air bubbles. If you look at cake with a magnifying glass, you can see the results of those bubbles. When sugar and chocolate are added the sugar caramelizes adding flavor and texture. Then when butter or oil is added it inhibits the gluten formation. Once again, the amount of each ingredient is crucial to get the desired flavor and texture.
Between the ages of 2-4 children ask why repetitively. This is because the world around them has come into focus and they want to understand All Of It! That curiosity can be nourished by presence and wonder all through our lives. So, when you have a craving for that perfect chocolate cake after a wonderful meal, we know it’s because of the neurons in our stomachs and if you are curious why a chocolate cake from your grandma tastes best it is because she has repeated a recipe that is tried and true!
