The purpose of this study is to examine the use of blood chemical tests as health indices by studies on the changes of nutrient intakes. These figures are taken from 278 healthy males in Tokushima prefecture.
Appling multiple regression and factor analysis, we found the following results.
1. Dietary intakes of energy and sugar correlated significantly with hemoglobin content, hematocrit and whole blood specific gravity. These tests also correlated with primary factors (size factors) indicative of the whole range nutrient intakes. Hematocrit was most effected by nutrient intakes in the blood chemical tests.
2. Dietary intakes of energy, sugar, and vitamin C correlated significantly with serum GOT, GPT activity. Serum GPT activity was most effected by vitamin C intake.
3. ZTT values were effected by age, sugar and vegetable protein. High inverse correlation was observed between ZTT values and primary factors.
4. Total serum cholesterol correlated only with animal fat intake.
