Based on the data of the investigation of nutritions with certain female dietetics junior college students and their families as subjects, the authors examined the types of frequency distribution of the volume of intake classified by food groups and by nutritional elements. The results were as follows:<BR>1. For the distribution types of the volume of intake classified by food groups, the groups found in the neighbourhood of the Pólya's distribution were cereals, potatoes, sugars, sweets, fruits, fish and shellfish, eggs, milk and dairy products, vegetables, mushrooms, seaweeds, and fancy drinks, while those found in the neighbourhood of the binomial distribution were oils and fats, and meats. Further, those found in the neighbourhood of Poisson's distribution were beans, coloured vegetables, and fruits. However, the normal distribution was not observable.<BR>2. The food groups showing a similar distribution to that observed in a national survey (1970: Toyokawa) were potatoes, beans, milk and dairy products, coloured vegetables, fruits, sweets, and seaweeds. Among these foods, potatoes fitted to Pblya's distribution, and agreed with the outcome of the national survey.<BR>3. Classified by the sex, the food groups found in the neighbourhood of Poisson's distribution both in men and wommen were sugars, fruits, meats, milk and dairy products, mushrooms, seaweeds, and fancy drinks. Oils and fats, beans, and coloured vegetables were found in the neighbourhood of Pólya's distribution for men, while the outcome for women was found in the neighbourhood of the binomial distribution.<BR>4. The cereals, which are the staple foods, were found in the neighbourhood of Poisson's distribution for men and in the neighbourhood of the binomial distributionin for women, whereas potatoes were found in the neighbourhood of the binomial distribution for men and in the neighbourhood of Poisson's distribution for women.<BR>5. In the distribution types of nutritional elements classified by the sex, energy, calsium, phosphor, and vitamin B<SUB>1</SUB> and B<SUB>2</SUB> were found in the neighbourhood of Pólya's distribution, and ashes were found in the neighbourhood of Poisson's distribution, both for men and women.<BR>6. As classified by the age, the neighbourhood of Poisson's distribution was shown more for the younger generation. For fish and shellfish, they were found in the neighbourhood of Pólya's distribution for adults while for youths they were found in the neighbourhood of Poisson's distribution.For meats, howerer, the outcome was reverse.<BR>7. It was noted that the significance of the mean as the representative value was restricted when observing the collective values, and therfore the authors' experiment to find out the distribution types from the frequency distribution classified by the volume of intake of food groups and nutritional elements, which led to the clarification of eating styles, appeared to be very significant.
