Abstract
Twenty female college students were divided into two groups and the subjects were given two types of test diet for 7 days. One diet was free from vegetables, fruits and/or potatoes and the other contained twice as much vegetables as usual dormitory foods. Daily nutrient intakes of the subjects in each group were calculated throughout the experimental period. Vitamin A, ascorbic acid, iron and crude fiber intakes in the vegetable-free group were significantly less than those in the vegetable-rich group. Blood ascorbic acid concentrations decreased significantly in the vegetable-free group, while that in the vegetable-rich group remained constant or slightly increased during the experimental period. Serum iron concentrations decreased in the vegetable-rich group. Result of blood analysis, counts of erythrocytes and leucocytes, 1evel of hemoglobin, hematocrit, MCV, MCH, MCHC and serum total protein were not affected by the different vegetable intakes. Some of the vegetable-free group comPlained of being lethargic, of being constipated or developing a rough skin, while most of the vegetablerich group were in good condition throughout the experimental period.
