Chocolate is rich in flavonoids, a class of antioxidant that helps to improve blood flow (and thus brain health) by regulating cholesterol and lowering blood pressure. High cocoa content in dark chocolate is best.

Dark chocolate boosts endorphines, the ‘feel good’ chemicals in the brain. These endorphines bind to opiate receptors in the brain, leading to a feeling of euphoria, similar to what a runner experiences during their ‘runners high.’ It is also highly concentrated in a brain boosting amino acid known as tryptophan, which is a precursor to seratonin, the neurotransmitter of happiness and positive mood.
