<p align="justify">Eating a high-carb breakfast, which includes bread, cheese and milk, may help you make good decisions throughout the day, say scientists who found that people who consume a lean meal in the morning tend to accept unfair financial offers.<br /><br />Researchers said that people's decision-making was often influenced by the amount of carbohydrates and protein contained in their breakfast.<br /><br />The study participants were more likely to reject an unfair financial offer if they had filled up on carbs that morning. However, if they had eaten a lower-carb, higher-protein breakfast, they were more apt to accept such offers.<br /><br />According to Soyoung Park from the University of Luebeck, in Germany, after a high-carb breakfast people tended to have lower levels of an amino acid called tyrosine.<br /><br />Tyrosine is important in producing brain chemicals like dopamine - which is part of the brain's "reward system." Changes in tyrosine correlated with changes in people's decision-making, Park said.<br /><br />In the first, Park's team had 87 college students play an online version of the Ultimatum Game. The game gives players the opportunity to either accept or reject a clearly unfair financial offer from an opponent. The catch is, if the offer is rejected, no one gets any money. So when a player makes that choice, it's seen as a form of "social punishment" for the opponent.<br /><br />After playing the game, the students told the researchers what they had eaten that morning. It turned out that 53 per cent of people who had eaten a high-carb breakfast rejected unfair offers, compared with only a quarter of students who had eaten a lower-carb breakfast.<br /><br />The second phase included 24 men who came to the lab for a controlled breakfast before playing the Ultimatum Game. They also had blood samples drawn over several hours.<br /><br />On one day, the breakfast was 80 per cent carbs, 10 per cent protein: Bread with jam and cream cheese; milk and apple juice; and an apple and banana.<br /><br />On another day, the breakfast was 50 per cent carbs and 25 per cent protein: There was bread and jam again, but also ham, yogurt, milk and a bigger slab of cream cheese.<br /><br />The results were similar. The men were more likely to reject unfair offers after the high-carb breakfast.<br /><br />The test included only men, Park said, because there are gender differences in metabolism that might have interfered with the results.<br /><br />Even in the all-male group, people varied in their responses. Some still accepted unfair offers after having a high-carb breakfast, for instance. It would be interesting to figure out why some people were influenced by the breakfast switch, and others were not, Giliberto sai.</p>
