Original language description

The study aims is to examine relationship between tyrosine and phenylalanine intake at breakfast as precursors of dopamine, and scores on the Torsvall-?kerstedt Diurnal Type Scale and of mental health in Japanese infants aged 2-5 years. An integrated questionnaire was administered to parents of 1367 infants attending one of 10 nurserys governed by Kochi City or a kindergarten of Kochi University (775 answers for analysis: 56.7%).
