| Abstract: | Habitual consumption of moderate amounts of fish is associated with reduced mortality from coronary heart disease. However
the beneficial effects of fish enriched diet seem contradictory, due to the susceptibility of the PUFAs in them to oxidation.
It is also acclaimed that vegetarians in general, have a lower serum total cholesterol and LDL-cholesterol and a better antioxidant
status. This contradiction was the basis for the study, where the validity of the above finding was tested in a general population
consuming a vegetarian or predominantly fish diet as a regular dietary habit. The oxidant status and the lipid profile of
23 vegetarians and 22 fish eaters was studied by estimating the plasma lipid peroxides measured as malondialdehyde (MDA) and
the lipid parameters viz. Total Cholesterol (TC), HDL-Cholesterol (HDL-C) and triglycerides (TG). Statistical analysis was
carried out to compare the MDA values and the lipemic status between the two groups. MDA was also correlated with the various
lipid indices among the study groups. None of the compared and correlated values was statistically significant, although certain
altered trends were seen. From this study, it may be concluded that oxidant status and lipid profile does not vary significantly
in the two groups, suggesting that neither a vegetarian diet nor a fish diet has a definite benefit over the other. |
