On April 16, 2007, BBC News reported the results of a study done by Dr. David Lewis of Mindlab International in the United Kingdom. Dr. Lewis found that eating dark chocolate had longer-lasting excitatory effects on the body than did kissing a romantic partner. From his statement, it is evident that Dr. Lewis:

Found Chocolate better and long lasting effect than kissing

Explanation: Dr. Lewis found chocolate better than kissing. From Dr. Lewis results reported by the British Broadcasting Corporation BBC it was observed that although kissing increased the excitatory ( excitation) like a burst in energy level of the heart it didn't have a long lasting effect, unlike the Chocolate which increased the heartbeat of the individuals from 60beats/ minutes to about 140 beats/ minutes. This observation was recorded from the Tests carried out on individuals.

The question is incomplete, but according to what was posed, dark chocolate generates, upon ingestion, the release of endorphins that are neurotransmitters that promote the stimulation of pleasure or happiness.

Explanation:

It is proven that dark chocolate also has a lower fat content, therefore it favors the circulatory system more and does not generate a fat reserve like milk chocolates.

On the other hand, the endorphins generated by eating the chocolate and mainly bitter not only interferes at the nervous level, but it was also proposed and found that the presence of endorphins improves the immune system, and blood pressure by promoting the release of nitrous oxide.

They are endogenous opioid peptides, that means that they are manufactured by our body.
