| Outline of Final Research Achievements |
The aim of this study was to elucidate the effect of amino acid intake on age-related changes in intelligence among Japanese middle-aged and elderly.
First, we constructed the Amino Acid Composition Table of Food containing amino acid compositions in 1,745 food items. In the examination about the effect of the proline intake to the age-related changes of the “Information” scores over a 10-years, as for the middle-aged men and women, the high intake group of proline derived from animal food was significantly increased, compared to the low intake group. Also, the elderly women in the high proline intake group maintained their scores higher than others in the low proline intake group. On the other hand, no significant relationship was observed between the plant-derived proline intake and the “Information” score. Animal-derived proline intake may have some benefit on maintaining age-related changes in intelligence among the middle-aged and elderly.
