A nutritional guidance plan was evaluated using two groups of children totalling 23 in number and ranging from 0 to 5 years in age using the author's original nutritional formula. For the 1st group consisting 15 children, the nutritional guidance was given continuously throughout 5 years, while for the 2nd group of 8, the guidance was given only during the year from birth until they reached the age of one. Physical conditions of both groups at the age of 5 were then observed with the wholehearted cooperation from mothers. The regular diets under this plan were supplemented by a food substance assumedly containing a large amount of the essential elements, chlorella algae on an average of 0.2g/kg body weight, and also by 10-22ml/day of chlorella algae hot water extract. We compared combinations of foods with a standard diet to determine relative high or low amounts of nutritional intake, and then assimilated the resultant standard numerical values with the height, weight, development of teeth, etc. of the study groups. Comparison of merits and demerits of each individual's health condition revealed that the 1st group far surpassed the second group in their health conditions. All results were numerically evaluated.
