This study was purported to investigate relationship between food intake and running ability in junior high school boys. Total number of foods taken per week, physical fitness, motor ability and running ability were measured several times for three years on the same subjects of a junior high school.
　The conclusions were revealed as follows:
　1) Boys who took 50-60 kinds of foods per week were most frequent among junior high school boys.
　2) No differences in physique, physical fitness and motor ability were found between the boys taking 60 or more kinds of foods and the boys taking 50 or less per week.
　3) The extreme upper group in food intake was inferior in skinfold measurement and superior in physical fitness and motor ability to the extreme lower group.
　4) No significant relationship was found between the number of food intake and running ability.
　5) The investigation of food intake itself seemed to be effective as a diet education.
