Abstract
Effects of vegetable oil intake on red cell physical properties and blood flow condition were evaluated. The study was done on two groups of volunteers taking either soybean oil (6 volunteers) or palm oil (another 6 subjects) for a period of eight weeks. The continuous effects were followed up after continuing the vegetable oil intake for another four weeks. Significant reduction in red cell deformability was demonstrated by laser diffractometry in both groups. The palm oil had greater extent in causing reduced red cell deformability as early as four weeks after the oil intake, whereas, such effect was shown in eight weeks after the soybean oil intake. The reducing effect of red cell deformability by palm oil intake was more obvious than that by the soybean oil intake as indicated by the fall of deformability index from the control by 47.6 per cent in palm oil and 21.9 per cent in the soybean oil group. The decrease still persisted and could be investigated on the four weeks' followup. The hematologic parameters measured by the laser-based instrument, the H*1 analyser were all within the normal ranges in both groups. However, the group taking soybean oil showed decreasing hemoglobin levels, which may be a physiological response to facilitate blood flow condition. The platelet volume was increased in both groups, indicating the possibility of adjustment of thrombopoiesis in the subjects although no clinical indication related to this finding was shown. In conclusion, intake of vegetable oil had an effect on red cell deformability. Soybean oil had an advantage over palm oil in having less effect on reducing the red cell deformability.
