Dutch study: Eating more eggs can be nice

you want to know what to eat that will make you more generous? That's a very common food -- eggs.a Dutch study has shown that eggs contain an essential amino acid that is an important ingredient in the brain's production of serotonin, the Sunday Independent reported. Serotonin mainly affects human emotions and social interactions, and people who secrete more will be friendlier and more willing to cooperate with others. The study suggests that by increasing the number of eggs ingies, people may be more kind.the Leyden Institute in the Netherlands invited
32,
people to participate in the experiment, half of which were given tryptophan powders equivalent to
3,
eggs, and the other half were controlled by powders without special content. The team later asked participants to donate a portion of the
10,
euro (about
70,
yuan) reward to charity, and found that people who took tryptophan donated an average of
1
euros (about
7,
yuan), twice as much as the normal group.
