Effect of Eating Habits on Personalities (Part 1)

Relationship between Food Preference and Personality Traits among School Children

Abstract

The purpose of the present investigation was to observe the effect of food preference on personality traits among school children. The results were as follows :
It was found that the food preference had to do with the emotional-, social-, active- and dominant-factor (except Agreeableness in boys, and Rhathymia, General Activity, Social Extraversion in girls), with some differences between boys and girls. The variances selected by variable appointment procedure of multiple regression analysis were 5 or 6, and they were mainly animal foods, potatoes, sweet pepper, seaweeds for boys, and the plant foods for girls. Their contribution ratios showed more than 80% of those estimated with all kinds of foods.
The estimation of discriminant functions with 5 or 6 variances made it possible to classify the samples into 2 groups (high score- and low score-group in each personality traits) with the misclassification ratios of about 17-31 % in range.
