Memories are held within groups of neurons called cell assemblies. They fire as a group in response to a specific stimulus, such as recognising your friend's face.
The more neurons fire together, the more the interconnection of the cells strengthen. We experience the nerves' collective activity as a memory.
A diet high in saturated fats and sugars affects your blood pressure, cholesterol, and blood sugar levels. It also affects the parts of the brain that are important to memory.
