What is the Connection Between Food and the Brain?

• Just like a car needs fuel, the human body, including the brain, requires energy to function. Your body receives this energy by breaking down glucose molecules with the help of oxygen. The glucose enters your bloodstream and reaches various organs, the brain, and cells, providing them with the energy required to perform their tasks. That is why the brain chemistry gets affected due to an inadequate supply of glucose in controlled eating, malnourishment, starvation, etc.

• Now if you are wondering why human beings feel happy, satisfied, sleepy, and irritated, as per the food they consume, it is so because your brain is connected to the food you consume especially, a channel of message transmitters, also known as neurons, between your stomach and brain. This channel of neurons is also known as the gut-brain axis. Therefore, your brain receives the status of your food consumption from the food inventory of the human body (stomach) and further passes on the signal to make you feel hungry, irritated, low, etc.
