Scientists at Cambridge University have found, that it’s better not to make any decisions on an empty stomach, otherwise one risks to act utterly impulsively and ineffective. The reason of it is the fact, that hunger reduces serotonin levels in the body, which affects the rationality of the decisions one makes.
Maintaining an optimal level of serotonin is indispensable, if one has a very responsible job. The substance suppresses aggression and helps work more effectively. In order to make more rational decisions, one needs to include dairy products, meat, nuts, bananas, soy and fish into their diet.
